程式可能會無法釋出系統資源。
Explanation
程式可能會無法釋出系統資源。

資源洩漏至少有兩種常見原因:

- 錯誤條件以及其他異常情況。

- 不確定程式的哪一部份負責釋放資源。

大部分的 Unreleased Resource 問題都會導致一般軟體可靠性問題,但是如果攻擊者蓄意觸發資源洩漏的話,攻擊者就可能會藉由耗盡資源集區的方式來發動 Denial of Service 攻擊。

範例:在正常情況下,以下程式碼會執行資料庫查詢,處理資料庫傳回的結果,然後關閉分配的 SqlConnection 物件。但是,如果在執行 SQL 或處理結果時發生異常,SqlConnection 物件將不會關閉。如果這種情況時常發生的話,那麼資料庫將會用盡可用指標,並且無法再執行任何 SQL 查詢。


...
SqlConnection conn = new SqlConnection(connString);
SqlCommand cmd = new SqlCommand(queryString);
cmd.Connection = conn;
conn.Open();
SqlDataReader rdr = cmd.ExecuteReader();
HarvestResults(rdr);
conn.Connection.Close();
...

Abstract
當加密的資料儲存在磁碟上,或者如果多次使用金鑰,則使用串流密碼是很危險的。
Explanation
串流密碼容易受到「金鑰重複使用」攻擊,也稱為「欺騙性密碼本」攻擊。此類型的弱點發生於多次使用同一金鑰時,因為可以輕鬆地透過 XOR 運算密碼文字的兩個字串,並將金鑰設為 Null,從而只留下透過 XOR 運算的純文字。由於人類語言以特定方式設定格式,因此,通常可以輕鬆復原原始的兩則訊息。
若要阻止上述攻擊,將需要使用全新的初始化向量 (IV),所以串流密碼不適用於儲存加密的資料,因為這表示:
1) 使用磁碟磁區做為 IV:
此方法不安全,因為每次需要修改儲存的資料時都要求重複使用同一 IV。
2) 使用會將全新 IV 對應到磁碟磁區的複雜系統:
此方法難以維護。這樣的方法需要持續進行更新 IV、需要是使用者不可讀取的,且加密文字需要佔用比未加密純文字更多的磁碟空間。

鑒於以上兩點,使用串流密碼而非區塊密碼來儲存加密資料是不利的。串流密碼的另一個問題是,其不提供驗證,因此容易受到「位元翻轉」攻擊。某些區塊密碼 (如「CTR」) 也容易受到這些攻擊,因為其功能類似於串流密碼。

範例 1:以下程式碼會建立串流密碼,此串流密碼用於以常數 IV 加密資料,並將其儲存在磁碟上:


import (
"crypto/aes"
"crypto/cipher"
"os"
)
...
iv = b'1234567890123456'
CTRstream = cipher.NewCTR(block, iv)
CTRstream.XORKeyStream(plaintext, ciphertext)
...
f := os.Create("data.enc")
f.Write(ciphertext)
f.Close()


Example 1 中,由於 iv 已設為常數初始化向量,因此容易受到重複使用攻擊。

Abstract
如果加密的資料將儲存在磁碟上,或者如果多次使用金鑰,則使用串流密碼是很危險的。
Explanation
串流密碼容易受到「金鑰重複使用」攻擊,也稱為「欺騙性密碼本」攻擊。這意味著,如果多次使用同一金鑰,則可以輕鬆地透過 XOR 運算密碼文字的兩個字串,並將金鑰設為 Null,從而只留下透過 XOR 運算的純文字。由於人類語言以特定方式設定格式,因此,通常可以輕鬆地恢復原始的兩條訊息。
由於需要使用全新的初始化向量 (IV) 來阻止上述攻擊,這意味著串流密碼不適用於儲存加密的資料,因為這表示:
1) 使用磁碟磁區做為 IV:
此方法不安全,因為每次需要修改儲存的資料時都要求重複使用同一 IV。
2) 具有會將全新 IV 對應到磁碟磁區的複雜系統:
此方法難以維護,因為需要持續進行更新、需要是使用者不可讀取的,且加密文字需要佔用比單獨的未加密純文字遠遠更多的磁碟空間。

鑒於以上兩點,出於儲存加密資料的目的使用串流密碼而非區塊密碼是不利的。串流密碼的另一個問題是,其不提供驗證,因此容易受到「位元翻轉」攻擊。某些區塊密碼 (如「CTR」) 也容易受到這些攻擊,因為其行為方式類似於串流密碼。

範例 1:以下程式碼片段會建立串流密碼,然後此串流密碼用於以常數 IV 加密資料,並將其儲存在磁碟上:


from Crypto.Cipher import AES
from Crypto import Random
...
key = Random.new().read(AES.block_size)
iv = b'1234567890123456'
cipher = AES.new(key, AES.MODE_CTR, iv, counter)
...
encrypted = cipher.encrypt(data)
f = open("data.enc", "wb")
f.write(encrypted)
f.close()
...


Example 1 中,由於 iv 已設為常數初始化向量,因此容易受到重複使用攻擊。

Abstract
停用檢視狀態訊息 Authentication 檢查 (MAC) 可讓攻擊者能夠修改 View State。
Explanation
在 ASP.NET,檢視狀態是一種在回傳 (postback) 間持續網路表單狀態的機制。檢視狀態中儲存的資料不受信任,因為沒有防止重複進行攻擊的機制。當停用檢視狀態訊息 Authentication 檢查時,信任檢視狀態將更為危險。停用此項檢查,會讓攻擊者對檢視狀態中儲存的資料任意進行變更,並製造對信任檢視狀態的程式碼的攻擊機會。攻擊者可使用這種錯誤來破解 Authentication 檢查或修改項目定價。
範例:以下程式碼停用檢視狀態訊息驗證檢查。

Page.EnableViewStateMac = false;

Abstract
識別的方法將資料寫入加密設定可能不足的檔案。
Explanation
資料保護 API 設計為允許應用程式宣告何時可以存取金鑰鏈中的項目以及檔案系統上儲存的檔案。這適用於大多數的檔案和資料庫 API,包括 NSFileManager、CoreData、NSData 和 SQLite。開發人員可以藉由將四種保護類別之一指定給某個指定資源,指示基礎檔案系統使用衍生自裝置 UID 和使用者密碼兩者的金鑰,或是使用完全以裝置 UID 為基礎的金鑰,對該資源進行加密 (以及何時自動對其進行解密)。

資料保護類別針對 NSFileManager 定義,而常數則應該被指派為與 NSFileManager 執行個體相關聯之 NSDictionary 中的 NSFileProtectionKey 金鑰值,以及可以透過使用 NSFileManager 函數 (包括 setAttributes:ofItemAtPath:error:attributesOfItemAtPath:error:createFileAtPath:contents:attributes:) 建立檔案或修改其資料保護類別。此外,相對應的資料保護常數會針對 NSData 物件定義為 NSDataWritingOptions,以便可以做為 options 引數傳遞到 NSData 函數 writeToURL:options:error:writeToFile:options:error:NSFileManagerNSData 的各種資料保護類別常數定義如下所示:

-NSFileProtectionComplete, NSDataWritingFileProtectionComplete:
資源會以加密格式儲存在磁碟,當裝置處於鎖定狀態或者正在開機時,將無法進行讀取或寫入。
可用於 iOS 4.0 及更新版本。
-NSFileProtectionCompleteUnlessOpen, NSDataWritingFileProtectionCompleteUnlessOpen:
資源會以加密格式儲存在磁碟。當裝置處於鎖定狀態時,可以建立資源,但是一旦關閉資源,就無法再次開啟,直到裝置解除鎖定。如果在解除鎖定時開啟了資源,則可以如常繼續存取資源,即使使用者鎖定了裝置也無妨。
可用於 iOS 5.0 及更新版本。
-NSFileProtectionCompleteUntilFirstUserAuthentication, NSDataWritingFileProtectionCompleteUntilFirstUserAuthentication:
資源會以加密格式儲存在磁碟,只有在裝置開機之後,才能存取資源。在使用者首次解除鎖定裝置之後,您的應用程式可以存取資源,即使使用者之後鎖定了裝置,還是可以繼續存取。
可用於 iOS 5.0 及更新版本。
-NSFileProtectionNone, NSDataWritingFileProtectionNone:
資源沒有與其相關聯的特殊保護。任何時候都可以讀取或寫入資源。
可用於 iOS 4.0 及更新版本。

所以,雖然以 NSFileProtectionCompleteUnlessOpenNSFileProtectionCompleteUntilFirstUserAuthentication 標記檔案將會使用衍生自使用者密碼和裝置 UID 的金鑰為其加密,但是在某些情況下資料還是保持可存取的狀態。因此,使用 NSFileProtectionCompleteUnlessOpenNSFileProtectionCompleteUntilFirstUserAuthentication 時應該仔細進行檢閱,以確定是否保證提供進一步的 NSFileProtectionComplete 保護。

範例 1:在以下範例中,只有在使用者開啟裝置並首次提供密碼後 (直到下次重新開機),所指定的檔案才受到保護:


...
filepath = [self.GetDocumentDirectory stringByAppendingPathComponent:self.setFilename];
...
NSDictionary *protection = [NSDictionary dictionaryWithObject:NSFileProtectionCompleteUntilFirstUserAuthentication forKey:NSFileProtectionKey];
...
[[NSFileManager defaultManager] setAttributes:protection ofItemAtPath:filepath error:nil];
...
BOOL ok = [testToWrite writeToFile:filepath atomically:YES encoding:NSUnicodeStringEncoding error:&err];
...
範例 2:在以下範例中,只有在使用者開啟裝置並首次提供密碼後 (直到下次重新開機),所指定的資料才受到保護:


...
filepath = [self.GetDocumentDirectory stringByAppendingPathComponent:self.setFilename];
...
NSData *textData = [textToWrite dataUsingEncoding:NSUnicodeStingEncoding];
...
BOOL ok = [textData writeToFile:filepath options:NSDataWritingFileProtectionCompleteUntilFirstUserAuthentication error:&err];
...

Abstract
識別的方法將資料寫入加密設定可能不足的檔案。
Explanation
資料保護 API 設計為允許應用程式宣告何時可以存取金鑰鏈中的項目以及檔案系統上儲存的檔案。這適用於大多數的檔案和資料庫 API,包括 NSFileManager、CoreData、NSData 和 SQLite。開發人員可以藉由將四種保護類別之一指定給某個指定資源,指示基礎檔案系統使用衍生自裝置 UID 和使用者密碼兩者的金鑰,或是使用完全以裝置 UID 為基礎的金鑰,對該資源進行加密 (以及何時自動對其進行解密)。

資料保護類別定義於 NSFileManager,而常數則應該被指派為與 NSFileManager 實例相關聯之 Dictionary 中的 NSFileProtectionKey 金鑰值,以及可以透過使用 NSFileManager 函數 (包括 setAttributes(_:ofItemAtPath:)attributesOfItemAtPath(_:)createFileAtPath(_:contents:attributes:)) 建立檔案或修改其資料保護類別。此外,相對應的資料保護常數會針對 NSDataWritingOptions 列舉中的 NSData 物件定義,以便可以做為 options 引數傳遞到 NSData 函數
writeToFile(_:options:)
NSFileManagerNSData 的各種資料保護類別常數定義如下所示:

-NSFileProtectionComplete, NSDataWritingOptions.DataWritingFileProtectionComplete:
資源會以加密格式儲存在磁碟,當裝置處於鎖定狀態或者正在開機時,將無法進行讀取或寫入。
可用於 iOS 4.0 及更新版本。
-NSFileProtectionCompleteUnlessOpen, NSDataWritingOptions.DataWritingFileProtectionCompleteUnlessOpen:
資源會以加密格式儲存在磁碟。當裝置處於鎖定狀態時,可以建立資源,但是一旦關閉資源,就無法再次開啟,直到裝置解除鎖定。如果在解除鎖定時開啟了資源,則可以如常繼續存取資源,即使使用者鎖定了裝置也無妨。
可用於 iOS 5.0 及更新版本。
-NSFileProtectionCompleteUntilFirstUserAuthentication, NSDataWritingOptions.DataWritingFileProtectionCompleteUntilFirstUserAuthentication:
資源會以加密格式儲存在磁碟,只有在裝置開機之後,才能存取資源。在使用者首次解除鎖定裝置之後,您的應用程式可以存取資源,即使使用者之後鎖定了裝置,還是可以繼續存取。
可用於 iOS 5.0 及更新版本。
-NSFileProtectionNone, NSDataWritingOptions.DataWritingFileProtectionNone:
資源沒有與其相關聯的特殊保護。任何時候都可以讀取或寫入資源。
可用於 iOS 4.0 及更新版本。

所以,雖然以 NSFileProtectionCompleteUnlessOpenNSFileProtectionCompleteUntilFirstUserAuthentication 標記檔案將會使用衍生自使用者密碼和裝置 UID 的金鑰為其加密,但是在某些情況下資料還是保持可存取的狀態。因此,使用 NSFileProtectionCompleteUnlessOpenNSFileProtectionCompleteUntilFirstUserAuthentication 時應該仔細進行檢閱,以確定是否保證提供進一步的 NSFileProtectionComplete 保護。

範例 1:在以下範例中,只有在使用者開啟裝置並首次提供密碼後 (直到下次重新開機),所指定的檔案才受到保護:


...
let documentsPath = NSURL(fileURLWithPath: NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0])
let filename = "\(documentsPath)/tmp_activeTrans.txt"
let protection = [NSFileProtectionKey: NSFileProtectionCompleteUntilFirstUserAuthentication]
do {
try NSFileManager.defaultManager().setAttributes(protection, ofItemAtPath: filename)
} catch let error as NSError {
NSLog("Unable to change attributes: \(error.debugDescription)")
}
...
BOOL ok = textToWrite.writeToFile(filename, atomically:true)
...
範例 2:在以下範例中,只有在使用者開啟裝置並首次提供密碼後 (直到下次重新開機),所指定的資料才受到保護:


...
let documentsPath = NSURL(fileURLWithPath: NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0])
let filename = "\(documentsPath)/tmp_activeTrans.txt"
...
BOOL ok = textData.writeToFile(filepath, options: .DataWritingFileProtectionCompleteUntilFirstUserAuthentication);
...

即使 iOS 裝置上的所有檔案 (包括未明確指派有資料保護類別的檔案) 都以加密格式儲存,指定 NSFileProtectionNone 也會導致使用完全以裝置 UID 為基礎的衍生金鑰進行加密。如此一來,在裝置開機的任何時候 (包括以密碼鎖定時或正在開機時),此類檔案都會處於可存取的狀態。因此,使用 NSFileProtectionNone 時應該仔細進行檢閱,以確定是否保證使用較嚴格的資料保護類別提供進一步的保護。

範例 1:在以下範例中,指定的檔案未受保護 (在裝置開機的任何時候均可存取):

desc.structural.swift.insecure_storage_lacking_data_protection
Abstract
允許使用者輸入來控制用於檔案系統作業的路徑,可讓攻擊者任意覆寫系統上的檔案。
Explanation
Path Manipulation:開啟並展開 Zip 檔案而沒有檢查 Zip 項目的檔案路徑時,發生 Zip Entry Overwrite 錯誤。

範例 1:以下範例會從 Zip 檔案解壓縮檔案,然後以不安全的方式將檔案寫入磁碟。


public static void UnzipFile(ZipArchive archive, string destDirectory)
{
foreach (var entry in archive.Entries)
{
string file = entry.FullName;
if (!string.IsNullOrEmpty(file))
{
string destFileName = Path.Combine(destDirectory, file);
entry.ExtractToFile(destFileName, true);

}
}
}


Example 1 中,沒有先驗證 entry.FullName,就對此項目中的資料執行讀/寫作業。如果 Zip 檔案原本是放置在「C:\TEMP」目錄中,而 Zip 項目名稱包含「..\ 片段」,且應用程式是在所需權限下執行,則會任意覆寫系統檔案。

Abstract
允許使用者輸入來控制用於檔案系統作業的路徑,可讓攻擊者任意覆寫系統上的檔案。
Explanation
Path Manipulation:開啟並展開 Zip 檔案而沒有檢查 Zip 項目的檔案路徑時,發生 Zip Entry Overwrite 錯誤。

範例 1:以下範例會從 Zip 檔案解壓縮檔案,然後以不安全的方式將檔案寫入磁碟。


ZZArchive* archive = [ZZArchive archiveWithURL:[NSURL fileURLWithPath: zipPath] error:&error];
for (ZZArchiveEntry* entry in archive.entries) {
NSString *fullPath = [NSString stringWithFormat: @"%@/%@", destPath, [entry fileName]];
[[entry newDataWithError:nil] writeToFile:newFullPath atomically:YES];
}


Example 1 中,沒有先驗證 entry.fileName,就對此項目中的資料執行讀/寫功能。如果 Zip 檔案原本是放置在 iOS 應用程式的「Documents/hot_patches」目錄中,Zip 項目為「../js/page.js」,將會覆寫 page.js 檔案。此舉進而會允許攻擊者插入可能會導致執行程式碼的惡意程式碼。

Abstract
允許使用者輸入來控制檔案系統作業中的路徑,可讓攻擊者任意覆寫系統上的檔案。
Explanation
Path Manipulation:開啟 Zip 檔案並解壓縮檔案而沒有檢查 Zip 項目的檔案路徑時,發生 Zip Entry Overwrite 錯誤。

範例 1:以下範例會從 Zip 檔案解壓縮檔案,然後以不安全的方式將檔案寫入磁碟。


...
$zip = new ZipArchive();
$zip->open("userdefined.zip", ZipArchive::RDONLY);
$zpm = $zip->getNameIndex(0);
$zip->extractTo($zpm);
...


Example 1 中,沒有先驗證 f.Name,就對此項目中的資料執行讀/寫功能。如果 Zip 檔案位於 Unix 機器的「/tmp/」目錄中,Zip 項目為「../etc/hosts」,並根據必要的權限執行應用程式,將會覆寫系統 hosts 檔案。此舉會允許從機器將流量送到攻擊者所要的任何位置,例如,返回攻擊者的機器。

desc.dataflow.python.path_manipulation_zip_entry_overwrite
Abstract
允許使用者輸入來控制用於檔案系統作業的路徑,可讓攻擊者任意覆寫系統上的檔案。
Explanation
Path Manipulation:開啟並展開 Zip 檔案而沒有檢查 Zip 項目的檔案路徑時,發生 Zip Entry Overwrite 錯誤。

範例 1:以下範例會從 Zip 檔案解壓縮檔案,然後以不安全的方式將檔案寫入磁碟。


import better.files._

...

val zipPath: File = getUntrustedZip()
val destinationPath = file"out/dest"
zipPath.unzipTo(destination = destinationPath)
範例 2:以下範例會從 Zip 檔案解壓縮檔案,然後以不安全的方式將檔案寫入磁碟。


import better.files._

...

val zipPath: File = getUntrustedZip()
val destinationPath = file"out/dest"
zipPath.newZipInputStream.mapEntries( (entry : ZipEntry) => {
entry.extractTo(destinationPath, new FileInputStream(entry.getName))
})


Example 2 中,沒有先驗證 entry.getName,就對此項目中的資料執行讀/寫功能。如果 Zip 檔案原本是放置在 Unix 機器的「/tmp/」目錄中,Zip 項目為「../etc/hosts」,並根據必要的權限執行應用程式,將會覆寫系統 hosts 檔案。此舉轉而會允許從機器將流量送到攻擊者所要的任何位置,例如,返回攻擊者的機器。

Abstract
允許使用者輸入來控制用於檔案系統作業的路徑,可讓攻擊者任意覆寫系統上的檔案。
Explanation
Path Manipulation:開啟並展開 Zip 檔案而沒有檢查 Zip 項目的檔案路徑時,發生 Zip Entry Overwrite 錯誤。

範例 1:以下範例會從 Zip 檔案解壓縮檔案,然後以不安全的方式將檔案寫入磁碟。


let archive = try ZZArchive.init(url: URL(fileURLWithPath: zipPath))

for entry in archive.entries {
let fullPath = URL(fileURLWithPath: destPath + "/" + entry.fileName)
try entry.newData().write(to: fullPath)
}


Example 1 中,沒有先驗證 entry.fileName,就對此項目中的資料執行讀/寫功能。如果 Zip 檔案原本是放置在 iOS 應用程式的「Documents/hot_patches」目錄中,Zip 項目為「../js/page.js」,將會覆寫 page.js 檔案。此舉進而會允許攻擊者插入可能會導致執行程式碼的惡意程式碼。

Abstract
應用程式無法在以 URL 為基礎的程序間通訊 (IPC) 呼叫中驗證呼叫 URL。
Explanation
第三方應用程式或 webview 使用某個 URL 與您的應用程式通訊時,接收應用程式應先驗證呼叫 URL,然後再執行進一步的動作。接收應用程式可以選擇是使用 UIApplicationDelegate application:didFinishLaunchingWithOptions: 還是 UIApplicationDelegate application:willFinishLaunchingWithOptions: 委派方法來開啟呼叫 URL。

範例 1:UIApplicationDelegate application:didFinishLaunchingWithOptions: 委派方法的以下實作無法驗證呼叫 URL 並且總是處理不可信賴的 URL:

Abstract
此方法將未經驗證的輸入寫入 JSON。此呼叫可讓攻擊者將任意元素或屬性注入 JSON 實體。
Explanation
JSON Injection 發生於:

1. 資料從一個不可信賴的來源進入程式。


2. 資料會寫入 JSON 串流。

應用程式通常使用 JSON 來儲存資料或傳送訊息。JSON 用於儲存資料時,通常視為快取資料,可能會包含敏感資訊。JSON 用於傳送訊息時,通常會與 RESTful 服務搭配使用,並且可以用於傳輸敏感資訊,例如驗證憑證。

如果應用程式從未驗證的輸入建構 JSON,則 JSON 文件和訊息的語義便可能會更改。在相對不具惡意的情況下,攻擊者可能會注入外來的元素,而造成應用程式在剖析 JSON 文件或要求時拋出一個異常。在更嚴重的情況下,例如涉及 JSON Injection,攻擊者可能會插入外來元素,而允許對 JSON 文件或要求內的營運關鍵值執行可預測的操作。在某些情況下,JSON Injection 可能引發 Cross-site scripting 或 Dynamic code 評估。

範例 1:以下 C# 程式碼使用 JSON.NET 從使用者控制的輸入變數 usernamepassword 將非特殊權限使用者的使用者帳戶驗證資訊 (這類使用者具有「default」角色,而具特殊權限之使用者具有「admin」角色) 序列化為位於 C:\user_info.json 的 JSON 檔案:


...

StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);

using (JsonWriter writer = new JsonTextWriter(sw))
{
writer.Formatting = Formatting.Indented;

writer.WriteStartObject();

writer.WritePropertyName("role");
writer.WriteRawValue("\"default\"");

writer.WritePropertyName("username");
writer.WriteRawValue("\"" + username + "\"");

writer.WritePropertyName("password");
writer.WriteRawValue("\"" + password + "\"");

writer.WriteEndObject();
}

File.WriteAllText(@"C:\user_info.json", sb.ToString());


然而,因為 JSON 序列化是使用 JsonWriter.WriteRawValue() 來執行的,所以將不會驗證 usernamepassword 中的不可信賴資料以逸出與 JSON 相關的特殊字元。如此便允許使用者任意插入 JSON 金鑰,進而可能變更已序列化之 JSON 的結構。在此範例中,如果密碼為 Evil123! 的非特殊權限使用者 mallory 在依設定 username 變數值的提示進行輸入時,將 ","role":"admin 附加至其使用者名稱,則產生並儲存到 C:\user_info.json 的 JSON 將會如下所示:


{
"role":"default",
"username":"mallory",
"role":"admin",
"password":"Evil123!"
}


如果此序列化的 JSON 檔案接著會使用 JsonConvert.DeserializeObject() 還原序列化為 Dictionary 物件,如下所示:


String jsonString = File.ReadAllText(@"C:\user_info.json");

Dictionary<string, string> userInfo = JsonConvert.DeserializeObject<Dictionary<string, strin>>(jsonString);
Dictionary 物件中 usernamepasswordrole 金鑰產生的值將分別是 malloryEvil123!admin。如果未進一步驗證還原序列化的 JSON 值是否有效,應用程式將會錯誤指派「admin」權限給使用者 mallory

Abstract
此方法將未經驗證的輸入寫入至 JSON。攻擊者可能將任意元素或屬性插入 JSON 實體。

...
func someHandler(w http.ResponseWriter, r *http.Request){
r.parseForm()
username := r.FormValue("username")
password := r.FormValue("password")
...
jsonString := `{
"username":"` + username + `",
"role":"default"
"password":"` + password + `",
}`
...
f, err := os.Create("~/user_info.json")
defer f.Close()

jsonEncoder := json.NewEncoder(f)
jsonEncoder.Encode(jsonString)
}


由於程式碼使用字串串連執行 JSON 序列化,所以將不會驗證 usernamepassword 中的不可信賴資料以逸出與 JSON 相關的特殊字元。如此便允許使用者任意插入 JSON 金鑰,進而可能變更已序列化之 JSON 的結構。在此範例中,如果密碼為 Evil123! 的非特殊權限使用者 mallory 在輸入自己的使用者名稱時附加了 ","role":"admin,則產生並儲存至 ~/user_info.json 的 JSON 將會如下所示:


{
"username":"mallory",
"role":"default",
"password":"Evil123!",
"role":"admin"
}

如果未進一步驗證還原序列化的 JSON 值是否有效,應用程式會在無意間指派「admin」權限給使用者 mallory

如果應用程式從未驗證的輸入建構 JSON,則 JSON 文件和訊息的語義便可能會更改。在相對不具惡意的情況下,攻擊者可能會注入外來的元素,而造成應用程式在剖析 JSON 文件或要求時拋出一個異常。在更嚴重的情況下,例如涉及 JSON Injection,攻擊者可能會插入外來元素,而允許對 JSON 文件或要求內的營運關鍵值執行可預測的操作。在某些情況下,JSON Injection 可能引發 Cross-site scripting 或 Dynamic code 評估。

範例 1:以下 JavaScript 程式碼使用 jQuery 在值來自 URL 的位置中剖析 JSON:


var str = document.URL;
var url_check = str.indexOf('name=');
var name = null;
if (url_check > -1) {
name = decodeURIComponent(str.substring((url_check+5), str.length));
}

$(document).ready(function(){
if (name !== null){
var obj = jQuery.parseJSON('{"role": "user", "name" : "' + name + '"}');
...
}
...
});


此處將不會驗證 name 中不可信賴的資料,以逸出與 JSON 相關的特殊字元。如此便允許使用者任意注入 JSON 金鑰,進而可能變更已序列化之 JSON 的結構。在此範例中,如果非特殊權限使用者 mallory","role":"admin 附加至 URL 中的名稱參數,JSON 會變成:


{
"role":"user",
"username":"mallory",
"role":"admin"
}


這會使用 jQuery.parseJSON() 進行剖析並設定為純物件,這表示 obj.role 現在會傳回 "admin",而不是 "user"

Abstract
此方法將未經驗證的輸入寫入 JSON。此呼叫可讓攻擊者將任意元素或屬性注入 JSON 實體。
Explanation
JSON Injection 發生於:

1. 資料從一個不可信賴的來源進入程式。


2. 資料會寫入 JSON 串流。

應用程式通常使用 JSON 來儲存資料或傳送訊息。JSON 用於儲存資料時,通常視為快取資料,可能會包含敏感資訊。JSON 用於傳送訊息時,通常會與 RESTful 服務搭配使用,並且可以用於傳輸敏感資訊,例如驗證憑證。

如果應用程式從未驗證的輸入建構 JSON,則 JSON 文件和訊息的語義便可能會更改。在相對不具惡意的情況下,攻擊者可能會注入外來的元素,而造成應用程式在剖析 JSON 文件或要求時拋出一個異常。在更嚴重的情況下,例如涉及 JSON Injection,攻擊者可能會插入外來元素,而允許對 JSON 文件或要求內的營運關鍵值執行可預測的操作。在某些情況下,JSON Injection 可能引發 Cross-site scripting 或 Dynamic code 評估。

範例 1:以下 Objective-C 程式碼會從使用者可控制的欄位 _usernameField_passwordField,將非特殊權限使用者的使用者帳戶驗證資訊 (這類使用者具有「default」角色,而具特殊權限之使用者具有「admin」角色) 序列化為 JSON:


...

NSString * const jsonString = [NSString stringWithFormat: @"{\"username\":\"%@\",\"password\":\"%@\",\"role\":\"default\"}" _usernameField.text, _passwordField.text];


然而,因為 JSON 序列化是使用 NSString.stringWithFormat: 來執行的,所以將不會驗證 _usernameField_passwordField 中的不可信賴資料以逸出與 JSON 相關的特殊字元。如此便允許使用者任意插入 JSON 金鑰,進而可能變更已序列化之 JSON 的結構。在此範例中,如果密碼為 Evil123! 的非特殊權限使用者 mallory 在輸入 _usernameField 欄位時,會將 ","role":"admin 附加至其使用者名稱,則產生的 JSON 將會如下所示:


{
"username":"mallory",
"role":"admin",
"password":"Evil123!",
"role":"default"
}


如果此序列化的 JSON 字串接著會使用 NSJSONSerialization.JSONObjectWithData: 還原序列化為 NSDictionary 物件,如下所示:


NSError *error;
NSDictionary *jsonData = [NSJSONSerialization JSONObjectWithData:[jsonString dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingAllowFragments error:&error];
NSDictionary 物件中產生的 usernamepasswordrole 值將分別是 malloryEvil123!admin。如果未進一步驗證還原序列化的 JSON 值是否有效,應用程式將會錯誤指派「admin」權限給使用者 mallory

範例:以下 python 程式碼使用來自 URL 的不受信任值更新 json 檔案:


import json
import requests
from urllib.parse import urlparse
from urllib.parse import parse_qs

url = 'https://www.example.com/some_path?name=some_value'
parsed_url = urlparse(url)
untrusted_values = parse_qs(parsed_url.query)['name'][0]

with open('data.json', 'r') as json_File:

json.dump(data, json_File)

{
"role":"user",
"username":"mallory",
"role":"admin"
}

JSON 檔案現在遭到使用惡意資料篡改,使用者擁有「admin」而不是「user」的特殊存取權

此方法將未經驗證的輸入寫入 JSON。此呼叫可讓攻擊者將任意元素或屬性注入 JSON 實體。
Explanation
JSON Injection 發生於:

1. 資料從一個不可信賴的來源進入程式。


2. 資料會寫入 JSON 串流。

應用程式通常使用 JSON 來儲存資料或傳送訊息。JSON 用於儲存資料時,通常視為快取資料,可能會包含敏感資訊。JSON 用於傳送訊息時,通常會與 RESTful 服務搭配使用,並且可以用於傳輸敏感資訊,例如驗證憑證。

如果應用程式從未驗證的輸入建構 JSON,則 JSON 文件和訊息的語義便可能會更改。在相對不具惡意的情況下,攻擊者可能會注入外來的元素,而造成應用程式在剖析 JSON 文件或要求時拋出一個異常。在更嚴重的情況下,例如涉及 JSON Injection,攻擊者可能會插入外來元素,而允許對 JSON 文件或要求內的營運關鍵值執行可預測的操作。在某些情況下,JSON Injection 可能引發 Cross-site scripting 或 Dynamic code 評估。

範例 1:以下 Swift 程式碼會從使用者可控制的欄位 usernameFieldpasswordField,將非特殊權限使用者的使用者帳戶驗證資訊 (這類使用者具有「default」角色,而具特殊權限之使用者具有「admin」角色) 序列化為 JSON:


...
let jsonString : String = "{\"username\":\"\(usernameField.text)\",\"password\":\"\(passwordField.text)\",\"role\":\"default\"}"


然而,因為 JSON 序列化是使用字串內插補點來執行的,所以將不會驗證 usernameFieldpasswordField 中不受信任的資料以逸出與 JSON 相關的特殊字元。如此便允許使用者任意注入 JSON 金鑰,進而可能變更已序列化之 JSON 的結構。在此範例中,如果密碼為 Evil123! 的非特殊權限使用者 mallory 在輸入 usernameField 欄位時,會將 ","role":"admin 附加至其使用者名稱,則產生的 JSON 將會如下所示:


{
"username":"mallory",
"role":"admin",
"password":"Evil123!",
"role":"default"
}


如果此序列化的 JSON 字串接著會使用 NSJSONSerialization.JSONObjectWithData: 還原序列化為 NSDictionary 物件,如下所示:


var error: NSError?
var jsonData : NSDictionary = NSJSONSerialization.JSONObjectWithData(jsonString.dataUsingEncoding(NSUTF8StringEncoding), options: NSJSONReadingOptions.MutableContainers, error: &error) as NSDictionary
NSDictionary 物件中產生的 usernamepasswordrole 值將分別是 malloryEvil123!admin。如果未進一步驗證還原序列化的 JSON 值是否有效,應用程式將會錯誤指派「admin」權限給使用者 mallory

Abstract
網域範圍過大的 Cookie 將使應用程式容易受到來自其他應用程式的攻擊。
Explanation
開發人員通常會將 Cookie 設為在基礎網域 (如「.example.com」) 內啟用。這會將 Cookie 揭露給基礎網域及任何子網域上的所有 Web 應用程式。由於 Cookie 通常具有敏感資訊 (如階段作業識別碼),因此在應用程式間共享 Cookie 可能會使一個應用程式中出現弱點,進而對另一個應用程式造成危害。

範例:
想像您已在 http://secure.example.com/ 部署安全的應用程式,且當使用者登入時,應用程式以網域「.example.com」設定階段作業 ID Cookie。

例如:

HttpCookie cookie = new HttpCookie("sessionID", sessionID);
cookie.Domain = ".example.com";


假設您在 http://insecure.example.com/ 有另一個較不安全的應用程式,且它含有 Cross-Site Scripting 弱點。 任何已向 http://secure.example.com 驗證的使用者在瀏覽 http://insecure.example.com 時,會造成向 http://secure.example.com 暴露其階段作業 Cookie 的風險。

除了讀取 Cookie 之外,攻擊者還有可能使用 insecure.example.com 來自行建立路徑範圍過大的 Cookie,藉此執行可從 secure.example.com 覆寫 Cookie 的 Cookie Poisoning 攻擊。

Abstract
網域範圍過大的 Cookie 將使應用程式容易受到來自其他應用程式的攻擊。
Explanation
開發人員通常會將 Cookie 設為在基礎網域 (如「.example.com」) 內啟用。這會將 Cookie 揭露給基礎網域及任何子網域上的所有 Web 應用程式。由於 Cookie 通常具有敏感資訊 (如階段作業識別碼),因此在應用程式間共享 Cookie 可能會使一個應用程式中出現弱點,進而對另一個應用程式造成危害。

範例 1:
想像您已在 http://secure.example.com/ 部署安全的應用程式,且當使用者登入時,應用程式以網域「.example.com」設定階段作業 ID Cookie。

例如:

...
NSDictionary *cookieProperties = [NSDictionary dictionary];
...
[cookieProperties setValue:@".example.com" forKey:NSHTTPCookieDomain];
...
NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];
...


假設您在 http://insecure.example.com/ 有另一個較不安全的應用程式,且它含有 Cross-site scripting 的弱點。任何已受 http://secure.example.com 驗證的使用者在瀏覽 http://insecure.example.com 時,會造成向 http://secure.example.com 暴露其階段作業 cookie 的風險。

除了讀取 cookie 之外,攻擊者還有可能使用 insecure.example.com 來自行建立過大範圍的 cookie,藉此執行可從 secure.example.com 覆寫 cookie 的 Cookie 下毒攻擊。

Abstract
網域範圍過大的 Cookie 將使應用程式容易受到來自其他應用程式的攻擊。
Explanation
開發人員通常會將 Cookie 設為在基礎網域 (如「.example.com」) 內啟用。這會將 Cookie 揭露給基礎網域及任何子網域上的所有 Web 應用程式。由於 Cookie 通常具有敏感資訊 (如階段作業識別碼),因此在應用程式間共享 Cookie 可能會使一個應用程式中出現弱點,進而對另一個應用程式造成危害。

範例 1:
想像您已在 http://secure.example.com/ 部署安全的應用程式,且當使用者登入時,應用程式以網域「.example.com」設定階段作業 ID Cookie。

例如:

...
let properties = [
NSHTTPCookieDomain: ".example.com",
NSHTTPCookiePath: "/service",
NSHTTPCookieName: "foo",
NSHTTPCookieValue: "bar",
NSHTTPCookieSecure: true
]
let cookie : NSHTTPCookie? = NSHTTPCookie(properties:properties)
...


假設您在 http://insecure.example.com/ 有另一個較不安全的應用程式,且它含有 Cross-Site Scripting 的弱點。任何已受 http://secure.example.com 驗證的使用者在瀏覽 http://insecure.example.com 時,會造成向 http://secure.example.com 暴露其階段作業 cookie 的風險。

除了讀取 cookie 之外,攻擊者還有可能使用 insecure.example.com 來自行建立過大範圍的 cookie,藉此執行可從 secure.example.com 覆寫 cookie 的 Cookie 下毒攻擊。

Abstract
顯示系統資料或除錯資訊有助於攻擊者瞭解系統並制訂攻擊計畫。
Explanation
在系統資料或除錯資訊離開程式,然後透過通訊端或網路連線前往遠端機器時,會發生外部資訊洩漏。
範例:下列程式碼會將 SAPFTP 版本資訊列印在螢幕上:


...
CALL FUNCTION 'FTP_VERSION'
...
IMPORTING
EXEPATH = p
VERSION = v
WORKING_DIR = dir
RFCPATH = rfcp
RFCVERSION = rfcv
TABLES
FTP_TRACE = FTP_TRACE.

WRITE: 'exepath: ', p, 'version: ', v, 'working_dir: ', dir, 'rfcpath: ', rfcp, 'rfcversion: ', rfcv.
...


根據選項螢幕的配置,可以將此資訊傾印到螢幕上,也可以直接傳送到印表機。在某些情況下,這個版本資訊正好可以告訴攻擊者這個系統容易受到哪種攻擊。透過相同的方式,錯誤訊息也可以告訴攻擊者系統容易受到哪種攻擊。例如,資料庫錯誤資訊即可揭露應用程式容易受到 SQL injection 攻擊。其他錯誤資訊還可揭露更多關於系統的間接線索。

Abstract
顯示系統資料或除錯資訊可讓攻擊者使用系統資訊制訂攻擊計畫。
Explanation
在系統資料或除錯資訊離開程式,然後透過通訊端或網路連線前往遠端機器時,會發生外部資訊洩漏。

範例 1:以下程式碼會將堆疊追蹤列印到「除錯」主控台或記錄檔:


try {
...
}
catch(e:Error) {
trace(e.getStackTrace());
}


根據系統配置,可以將資訊傾印到主控台,寫入記錄檔,或者顯示給遠端使用者。例如,使用指令碼機制時,將輸出資訊從「標準錯誤」或「標準輸出」重新導向至檔案或其他程式的過程是不太有意義的。此外,程式執行所在的系統可能會有遠端記錄機制,例如會將記錄傳送至遠端裝置的「syslog」伺服器。在開發期間,您沒有方法可得知從何處會結束顯示此資訊。

在某些情況下,錯誤資訊會清楚地告訴攻擊者系統容易受到哪種攻擊。例如,資料庫錯誤訊息即可揭露應用程式容易受到 SQL injection 攻擊。其他錯誤訊息還可揭露更多關於系統的間接線索。在 Example 1 中,搜索路徑可能會暗示有關作業系統類型、系統上安裝的應用程式,以及管理員在配置程式時所花費的努力等資訊。

Abstract
顯示系統資料或除錯資訊,讓攻擊者能瞭解系統並制訂攻擊計畫。
Explanation
在系統資料或除錯資訊離開程式,然後透過通訊端或網路連線前往遠端機器時,會發生外部資訊洩漏。外部洩漏可能揭露有關作業系統、完整路徑名稱、使用者名稱的存在狀態,或組態設定檔案位置的特定資料,進而幫助攻擊者。外部洩漏比內部資訊洩漏更嚴重,因為攻擊者比較難存取內部資訊。

範例 1:以下程式碼會在 Visualforce 頁面的 <apex:messages/> 元素中洩漏異常資訊:


try {
...
} catch (Exception e) {
ApexPages.Message msg = new ApexPages.Message(ApexPages.Severity.FATAL, e.getMessage());
ApexPages.addMessage(msg);
}


此資訊可能會暴露給遠端使用者。在某些情況下,錯誤訊息會為攻擊者提供系統容易受到哪些確切的攻擊類型影響。例如,資料庫錯誤訊息即可揭露應用程式容易受到 SQL injection 攻擊。其他錯誤訊息還可揭露更多關於系統的間接線索。

Abstract
顯示系統資料或除錯資訊有助於攻擊者瞭解系統並制訂攻擊計畫。
Explanation
在系統資料或除錯資訊離開程式,然後透過通訊端或網路連線前往遠端機器時,會發生外部資訊洩漏。
範例 1:以下程式碼會在 HTTP 回應中洩漏異常資訊:


try
{
...
}
catch (Exception e)
{
Response.Write(e.ToString());
}


此資訊可能會暴露給遠端使用者。在某些情況下,錯誤訊息會為攻擊者提供系統容易受到哪些確切的攻擊類型影響。例如,資料庫錯誤訊息即可揭露應用程式容易受到 SQL injection 攻擊。其他錯誤訊息還可揭露更多關於系統的間接線索。在 Example 1 中,洩漏的資訊可能會暗示有關作業系統類型、系統上安裝的應用程式,以及管理員在配置程式時所花費的努力等資訊。

Abstract
顯示系統資料或除錯資訊有助於攻擊者瞭解系統並制訂攻擊計畫。
Explanation
在系統資料或除錯資訊離開程式,然後透過通訊端或網路連線前往遠端機器時,會發生外部資訊洩漏。
範例 1:以下程式碼會透過通訊端洩漏系統資訊:


int sockfd;
int flags;
char hostname[1024];
hostname[1023] = '\0';
gethostname(hostname, 1023);
...
sockfd = socket(AF_INET, SOCK_STREAM, 0);
flags = 0;
send(sockfd, hostname, strlen(hostname), flags);


此資訊可暴露給遠端使用者。在某些情況下,這個錯誤資訊正好可以告訴攻擊者這個系統被入侵的可能性有多大。例如,資料庫錯誤訊息即可揭露應用程式容易受到 SQL injection 攻擊。其他錯誤訊息還可揭露更多關於系統的間接線索。在 Example 1 中,搜索路徑可能會暗示有關作業系統類型、系統上安裝的應用程式,以及管理員在配置程式時所花費的努力等資訊。

Abstract
顯示系統資料或除錯資訊有助於攻擊者瞭解系統並制訂攻擊計畫。
Explanation
在系統資料或除錯資訊離開程式,然後透過通訊端或網路連線前往遠端機器時,會發生外部資訊洩漏。

範例 1:以下範例會透過 HTTP 回應洩漏系統資訊。


func handler(w http.ResponseWriter, r *http.Request) {
host, err := os.Hostname()
...
fmt.Fprintf(w, "%s is busy, please try again later.", host)
}


在某些情況下,錯誤訊息會告訴攻擊者系統容易受到哪些確切的攻擊類型影響。例如,資料庫錯誤訊息即可揭露應用程式容易受到 SQL injection 攻擊。其他錯誤訊息還可揭露更多關於系統的間接線索。在 Example 1 中,洩漏的資訊可能會暗示有關作業系統類型、系統上安裝的應用程式,以及管理員在配置程式時所花費的努力等資訊。

Abstract
顯示系統資料或除錯資訊有助於攻擊者瞭解系統並制訂攻擊計畫。
Explanation
在系統資料或除錯資訊離開程式,然後透過通訊端或網路連線前往遠端機器時,會發生外部資訊洩漏。外部洩漏可能會向攻擊者洩漏有關作業系統、完整路徑名稱、存在的使用者名稱或組態設定檔位置的特定資料,較內部資訊洩漏更嚴重,因為攻擊者存取這些資料的難度更大。

範例 1:以下程式碼會在 HTTP 回應中洩漏異常資訊:


protected void doPost (HttpServletRequest req, HttpServletResponse res) throws IOException {
...
PrintWriter out = res.getWriter();
try {
...
} catch (Exception e) {
out.println(e.getMessage());
}
}


此資訊可能會暴露給遠端使用者。在某些情況下,錯誤訊息會為攻擊者提供系統容易受到哪些確切的攻擊類型影響。例如,資料庫錯誤訊息即可揭露應用程式容易受到 SQL injection 攻擊。其他錯誤訊息還可揭露更多關於系統的間接線索。在 Example 1 中,洩漏的資訊可能會暗示有關作業系統類型、系統上安裝的應用程式,以及管理員在配置程式時所花費的努力等資訊。

在行動運算環境中,資訊洩漏也是令人擔心的事情。使用行動平台時,會從多種來源下載,並在相同裝置上一起執行應用程式。在金融應用程式旁執行惡意程式碼的可能性很高,因此應用程式作者需要留意向裝置上執行的其他應用程式傳送的訊息中應包括哪些資訊。

範例 2:以下程式碼會向註冊的所有 Android 接收者廣播所捕捉異常的堆疊追蹤。

...
try {
...
} catch (Exception e) {
String exception = Log.getStackTraceString(e);
Intent i = new Intent();
i.setAction("SEND_EXCEPTION");
i.putExtra("exception", exception);
view.getContext().sendBroadcast(i);
}
...


以下是行動環境中特有的另一種狀況。現在,多數行動裝置執行近距離無線通訊 (NFC) 通訊協定,以使用無線電通訊在裝置之間快速共用資訊。裝置距離極為接近或彼此接觸時,才會實現此通訊。即使將 NFC 的通訊範圍限制在幾公分距離,也可能發生竊聽、資料修改及其他多種類型的攻擊,因為 NFC 本身並不能確保安全通訊。

範例 3:Android 平台提供對 NFC 的支援。以下程式碼建立進入範圍內其他裝置的訊息。

...
public static final String TAG = "NfcActivity";
private static final String DATA_SPLITTER = "__:DATA:__";
private static final String MIME_TYPE = "application/my.applications.mimetype";
...
TelephonyManager tm = (TelephonyManager)Context.getSystemService(Context.TELEPHONY_SERVICE);
String VERSION = tm.getDeviceSoftwareVersion();
...
NfcAdapter nfcAdapter = NfcAdapter.getDefaultAdapter(this);
if (nfcAdapter == null)
return;

String text = TAG + DATA_SPLITTER + VERSION;
NdefRecord record = new NdefRecord(NdefRecord.TNF_MIME_MEDIA,
MIME_TYPE.getBytes(), new byte[0], text.getBytes());
NdefRecord[] records = { record };
NdefMessage msg = new NdefMessage(records);
nfcAdapter.setNdefPushMessage(msg, this);
...


NFC 資料交換格式 (NDEF) 訊息包含輸入的資料、URI 或自訂應用程式裝載。若訊息包含應用程式的相關資訊 (例如其名稱、MIME 類型或裝置軟體版本),則可能會向竊聽者洩漏此資訊。

Abstract
顯示系統資料或除錯資訊可讓攻擊者使用系統資訊制訂攻擊計畫。
Explanation
在系統資料或除錯資訊離開程式,然後透過通訊端或網路連線前往遠端機器時,會發生外部資訊洩漏。外部洩漏可能會向攻擊者洩漏有關作業系統、完整路徑名稱、存在的使用者名稱或組態設定檔位置的特定資料,較內部資訊洩漏更嚴重,因為攻擊者存取這些資料的難度更大。

範例 1:以下程式碼會在 HTTP 回應中洩漏異常資訊:


protected fun doPost(req: HttpServletRequest, res: HttpServletResponse) {
...
val out: PrintWriter = res.getWriter()
try {
...
} catch (e: Exception) {
out.println(e.message)
}
}


此資訊可能會暴露給遠端使用者。在某些情況下,錯誤訊息會為攻擊者提供系統容易受到哪些確切的攻擊類型影響。例如,資料庫錯誤訊息即可揭露應用程式容易受到 SQL injection 攻擊。其他錯誤訊息還可揭露更多關於系統的間接線索。在 Example 1 中,洩漏的資訊可能會暗示有關作業系統類型、系統上安裝的應用程式,以及管理員在配置程式時所花費的努力等資訊。

在行動運算環境中,資訊洩漏也是令人擔心的事情。使用行動平台時,會從多種來源下載,並在相同裝置上一起執行應用程式。在金融應用程式旁執行惡意程式碼的可能性很高,因此開發人員需要留意向裝置上執行的其他應用程式傳送的訊息中應包括哪些資訊。

範例 2:以下程式碼會向註冊的所有 Android 接收者廣播所捕捉異常的堆疊追蹤。

...
try {
...
} catch (e: Exception) {
val exception = Log.getStackTraceString(e)
val intent = Intent()
intent.action = "SEND_EXCEPTION"
intent.putExtra("exception", exception)
view.context.sendBroadcast(intent)
}
...


以下是行動環境中特有的另一種狀況。現在,多數行動裝置執行近距離無線通訊 (NFC) 通訊協定,以使用無線電通訊在裝置之間快速共用資訊。裝置距離極為接近或彼此接觸時,才會實現此通訊。即使將 NFC 的通訊範圍限制在幾公分距離,也可能發生竊聽、資料修改及其他多種類型的攻擊,因為 NFC 本身並不能確保安全通訊。

範例 3:Android 平台提供對 NFC 的支援。以下程式碼建立進入範圍內其他裝置的訊息。

...
companion object {
const val TAG = "NfcActivity"
private const val DATA_SPLITTER = "__:DATA:__"
private const val MIME_TYPE = "application/my.applications.mimetype"
}
...
val tm = Context.getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager
val VERSION = tm.getDeviceSoftwareVersion();
...
val nfcAdapter = NfcAdapter.getDefaultAdapter(this)

val text: String = "$TAG$DATA_SPLITTER$VERSION"
val record = NdefRecord(NdefRecord.TNF_MIME_MEDIA, MIME_TYPE.getBytes(), ByteArray(0), text.toByteArray())
val records = arrayOf(record)
val msg = NdefMessage(records)
nfcAdapter.setNdefPushMessage(msg, this)
...


NFC 資料交換格式 (NDEF) 訊息包含輸入的資料、URI 或自訂應用程式裝載。若訊息包含應用程式的相關資訊 (例如其名稱、MIME 類型或裝置軟體版本),則可能會向竊聽者洩漏此資訊。

Abstract
顯示系統資料或除錯資訊有助於攻擊者瞭解系統並制訂攻擊計畫。
Explanation
在系統資料或除錯資訊離開程式,然後透過通訊端或網路連線前往遠端機器時,會發生外部資訊洩漏。

範例 1:以下程式碼會將異常寫入 HTTP 回應:


<?php
...
echo "Server error! Printing the backtrace";
debug_print_backtrace();
...
?>


根據系統配置,可以將資訊傾印到主控台,寫入記錄檔,或者顯示給遠端使用者。例如,使用指令碼機制時,將輸出資訊從「標準錯誤」或「標準輸出」重新導向至檔案或其他程式的過程是不太有意義的。此外,程式執行所在的系統可能會有遠端記錄機制,例如會將記錄傳送至遠端裝置的「syslog」伺服器。在開發期間,您沒有方法可得知從何處會結束顯示此資訊。

在某些情況下,錯誤訊息會為攻擊者提供系統容易受到哪些確切的攻擊類型影響。例如,資料庫錯誤訊息即可揭露應用程式容易受到 SQL injection 攻擊。其他錯誤訊息還可揭露更多關於系統的間接線索。在 Example 1 中,洩漏的資訊可能會暗示有關作業系統類型、系統上安裝的應用程式,以及管理員在配置程式時所花費的努力等資訊。

Abstract
顯示系統資料或除錯資訊有助於攻擊者了解系統並制訂攻擊計畫。
Explanation
在系統資料或除錯資訊離開程式,然後透過通訊端或網路連線前往遠端機器時,會發生外部資訊洩漏。

範例 1:以下程式碼將所有系統環境變數列印成 HTTP 回應的一部分:


...
import cgi
cgi.print_environ()
...


根據系統配置,可以將資訊傾印到主控台,寫入記錄檔,或者顯示給遠端使用者。例如,使用指令碼機制時,將輸出資訊從「標準錯誤」或「標準輸出」重新導向至檔案或其他程式的過程是不太有意義的。此外,程式執行所在的系統可能會有遠端記錄機制,例如會將記錄傳送至遠端裝置的「syslog」伺服器。在開發期間,您沒有方法可得知從何處會結束顯示此資訊。

在某些情況下,錯誤訊息會為攻擊者提供系統容易受到哪些確切的攻擊類型影響。例如,資料庫錯誤訊息即可揭露應用程式容易受到 SQL injection 攻擊。其他錯誤訊息還可揭露更多關於系統的間接線索。在 Example 1 中,洩漏的資訊可能會暗示有關作業系統類型、系統上安裝的應用程式,以及管理員在配置程式時所花費的努力等資訊。

Abstract
顯示系統資料或除錯資訊有助於攻擊者了解系統並制訂攻擊計畫。
Explanation
在系統資料或除錯資訊離開程式,然後透過通訊端或網路連線前往遠端機器時,會發生外部資訊洩漏。

範例 1:以下程式碼會透過 HTTP 回應洩漏系統資訊:


response = Rack::Response.new
...
stacktrace = caller # Kernel#caller returns an array of the execution stack
...
response.finish do |res|
res.write "There was a problem: #{stacktrace}"

Abstract
顯示系統資料或除錯資訊可讓攻擊者使用系統資訊制訂攻擊計畫。
Explanation
在系統資料或除錯資訊離開程式,然後透過通訊端或網路連線前往遠端機器時,會發生外部資訊洩漏。外部洩漏可能會向攻擊者洩漏有關作業系統、完整路徑名稱、存在的使用者名稱或組態設定檔位置的特定資料,較內部資訊洩漏更嚴重,因為攻擊者存取這些資料的難度更大。

範例 1:以下程式碼會在 HTTP 回應中洩漏系統詳細資料:


def doSomething() = Action { request =>
...
Ok(Html(Properties.osName)) as HTML
}


此資訊可能會暴露給遠端使用者。在某些情況下,錯誤訊息會為攻擊者提供系統容易受到哪些確切的攻擊類型影響。例如,資料庫錯誤訊息即可揭露應用程式容易受到 SQL injection 攻擊。其他錯誤訊息還可揭露更多關於系統的間接線索。在 Example 1 中,洩漏的資訊可能會暗示有關作業系統類型、系統上安裝的應用程式,以及管理員在配置程式時所花費的努力等資訊。

Abstract
顯示系統資料或除錯資訊有助於攻擊者了解系統並制訂攻擊計畫。
Explanation
在系統資料或除錯資訊離開程式,然後透過通訊端或網路連線前往遠端機器時,會發生外部資訊洩漏。

範例:以下程式碼會透過 HTTP 要求洩漏系統資訊:


let deviceName = UIDevice.currentDevice().name
let urlString : String = "http://myserver.com/?dev=\(deviceName)"
let url : NSURL = NSURL(string:urlString)
let request : NSURLRequest = NSURLRequest(URL:url)
var err : NSError?
var response : NSURLResponse?
var data : NSData = NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error:&err)


此資訊可暴露給遠端使用者。在某些情況下,這個錯誤資訊正好可以告訴攻擊者這個系統被入侵的可能性有多大。例如,資料庫錯誤資訊即可揭露應用程式容易受到 SQL injection 攻擊。其他錯誤資訊還可揭露更多關於系統的間接線索。

Abstract
顯示系統資料或除錯資訊可讓攻擊者使用系統資訊制訂攻擊計畫。
Explanation
在系統資料或除錯資訊離開程式,然後透過通訊端或網路連線前往遠端機器時,會發生外部資訊洩漏。

範例 1:以下程式碼會將異常寫入 Response 輸出串流:


...
If Err.number <>0 then
Response.Write "An Error Has Occurred on this page!<BR>"
Response.Write "The Error Number is: " & Err.number & "<BR>"
Response.Write "The Description given is: " & Err.Description & "<BR>"
End If
...


根據系統配置,可以將資訊傾印到主控台,寫入記錄檔,或者顯示給遠端使用者。例如,使用指令碼機制時,將輸出資訊從「標準錯誤」或「標準輸出」重新導向至檔案或其他程式的過程是不太有意義的。此外,程式執行所在的系統可能會有遠端記錄機制,例如會將記錄傳送至遠端裝置的「syslog」伺服器。在開發期間,您沒有方法可得知從何處會結束顯示此資訊。

在某些情況下,錯誤訊息會為攻擊者提供系統容易受到哪些確切的攻擊類型影響。例如,資料庫錯誤訊息即可揭露應用程式容易受到 SQL injection 攻擊。其他錯誤訊息還可揭露更多關於系統的間接線索。在 Example 1 中,洩漏的資訊可能會暗示有關作業系統類型、系統上安裝的應用程式,以及管理員在配置程式時所花費的努力等資訊。

Abstract
停用表頭檢查會替攻擊者製造執行表頭操作攻擊的機會。
Explanation
依照預設,.NET framework 會防止將新行字元傳送到設定 HTTP 表頭值的 API。不過,可透過將 HttpRuntimeSection 物件的 EnableHeaderChecking 特性設為 false,在程式上停用此行為。

範例:以下程式碼停用表頭檢查。

Configuration config = WebConfigurationManager.OpenWebConfiguration("/MyApp");
HttpRuntimeSection hrs = (HttpRuntimeSection) config.GetSection("system.web/httpRuntime");
hrs.EnableHeaderChecking = false;


停用此項檢查時,允許使用者輸入取得表頭設定 API 的程式碼將容易受到攻擊 (如 HTTP Response Splitting)。

Abstract
程式未使用 Cookie 來傳輸工作階段識別碼,這可能會替 Session Fixation 及 Session Hijacking 製造攻擊的機會。
Explanation
多數 Web 應用程式使用工作階段識別碼來識別各使用者,該識別碼通常儲存在 Cookie 中,並在伺服器與網路瀏覽器間公開傳輸。


屬性的值設定為 trueUseUri 時,無論瀏覽器或裝置是否支援 Cookie,應用程式都不會使用 Cookie。屬性的值設定為 AutoDetectUseDeviceProfile 時,根據要求的瀏覽器或裝置的組態,不會使用 Cookie。

未在 Cookie 中儲存工作階段識別碼的應用程式,有時會傳輸識別碼做為 HTTP 要求參數或 URL 的一部份。接受 URL 中指定的工作階段識別碼,容易讓攻擊者執行 Session Fixation 攻擊。

將工作階段識別碼置於 URL,也可能會增加 Session Hijacking 對應用程式成功攻擊的機會。當攻擊者控制受害者啟用的工作階段或工作階段識別碼時,Session Hijacking 便會發生。網路伺服器、應用程式伺服器及 Web 代理伺服器通常會儲存要求的 URL,這是種常見的作法。若 URL 中包含工作階段識別碼,也會記錄這些識別碼。增加工作階段識別碼檢視及儲存位置的數量,將增加攻擊者危及這些識別碼的機會。

Abstract
Ansible 工作將定義一個具有公開存取權的 Amazon RDS 執行個體。
Explanation
可公開存取的 Amazon RDS 執行個體不必要地擴大了組織的受攻擊面。開放與公眾互動的服務會受到攻擊者幾乎連續的掃描和探測。

範例 1:以下 Ansible 工作設定了一個具有公開存取權的 RDS 執行個體,因為 publicly_accessible 設定為 true

- name: createdb
community.aws.rds_instance:
db_instance_identifier: test-db
engine: aurora
instance_type: db.t2.small
username: "{{ username }}"
password: "{{ password }}"
cluster_id: test-cluster
publicly_accessible: true

Abstract
組態定義一個存取權限過寬的網路規則。
Explanation
寬鬆的存取組態會將系統暴露在外,並擴大組織的受攻擊面。開放與公眾互動的服務通常會受到惡意實體近乎連續的掃描和探測。

在發現並發佈針對公開服務的零時差攻擊 (例如 Heartbleed) 時問題特別大。攻擊者可主動追蹤和搜尋未修補和暴露的系統以進行攻擊。
