Explanation
MIME 攔截,是檢查位元組資料流內容的作法,可嘗試推算其內資料的檔案格式。

如果不明確停用 MIME 攔截,則某些瀏覽器可能會遭受操縱,從而以非預期的方式解譯資料,導致出現 Cross-site scripting 攻擊。

對於可能包含使用者可控內容的每個頁面,您應該使用 HTTP 表頭 X-Content-Type-Options: nosniff

Abstract
應用程式套用 MIME 攔截演算法,或未將 X-Content-Type-Options 設定為 nosniff
Explanation
MIME 攔截是檢查位元組串流內容的做法,可嘗試推算其中所包含資料的檔案格式。

如果不明確停用 MIME 攔截,則某些瀏覽器可能會遭受操縱,從而以非預期的方式解譯資料,導致出現 Cross-Site Scripting 攻擊。
撰寫 Web 應用程式時,請將 HTTP 標頭 X-Content-Type-Options: nosniff 用於可能含有使用者可控制內容的每個頁面中。
撰寫用戶端應用程式時,不得使用 MIME 攔截演算法確定伺服器的回應 Content-Type。

範例 1:下列程式碼使用 net.http.DetectContentType() 確定資源 Content-Type:


...
resp, err := http.Get("http://example.com/")
if err != nil {
// handle error
}
defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body)

content_type := DetectContentType(body)
...

Abstract
應用程式不會將 X-Content-Type-Options 設定為 nosniff,或明確停用此安全性標頭。
Explanation
MIME 攔截是檢查位元組串流內容的做法,可推算其中所包含資料的檔案格式。

如果未明確停用 MIME 攔截,攻擊者可以操縱某些瀏覽器以非預期的方式解譯資料,進行導致出現 Cross-Site Scripting 攻擊。對於可能包含使用者可控內容的每個頁面,您應該使用 HTTP 標頭 X-Content-Type-Options: nosniff

範例 1:以下程式碼會將受 Spring Security 保護的應用程式設定為停用 MIME 攔截保護:

<http auto-config="true">
...
<headers>
...
<content-type-options disabled="true"/>
</headers>
</http>

Abstract
配置不正確的內容安全性原則 (CSP) 會使應用程式面臨用戶端威脅,包括 Cross-site scripting、跨框架指令碼和跨網站偽造要求。
Explanation
內容安全性原則 (CSP) 是一種宣告式安全性標頭,可讓開發人員指示在網頁瀏覽器中轉譯時,允許網站從哪些網域載入內容或起始到哪些網域的連線。除了程式碼中的輸入驗證和檢查允許清單外,它還提供額外一層的安全性,以防禦重要弱點,例如,Cross-Site Scripting、Clickjacking、Cross-Origin Access 等。但設定不當的標頭無法提供這種額外一層的安全性。該原則藉助於 15 個指令進行定義,其中包括 8 個用於控制資源存取的指令,即:script-srcimg-srcobject-srcstyle_srcfont-srcmedia-srcframe-srcconnect-src

每個指令都使用來源清單做為一個值,此值指定針對該指令所涵蓋的功能,網站可存取的網域。開發人員可使用萬用字元 * 來指示所有或部分來源。所有指令都不是強制性的。瀏覽器將允許未列示指令的所有來源,或從選用的 default-src 指令衍生值。此外,此表頭的規格隨著時間的推移而不斷演變。在第 23 版之前的 Firefox 和第 10 版之前的 IE 中,其實做為 X-Content-Security-Policy,而在第 25 版之前的 Chrome 中,其實做為 X-Webkit-CSP。兩個名稱都已棄用,取代為現在的標準名稱 Content Security Policy。鑒於指令的數目、兩個棄用的替代名稱,以及對待多次出現之同一表頭和單一表頭中重複指令的方式,開發人員很可能會錯誤地配置此表頭。

考慮以下配置錯誤的情況:

- 具有 unsafe-inlineunsafe-eval 的指令違背了 CSP 的目的。
- 已設定 script-src 指令,但未配置任何 Script nonce
- 已設定 frame-src,但未配置任何 sandbox
- 在同一回應中允許使用此表頭的多個實例。開發團隊和安全性團隊可能都會設定表頭,但其中一個可能會使用棄用的名稱之一。雖然在不存在具有最新名稱 (即,內容安全性原則) 的表頭時會接受棄用的表頭,但如果存在具有 content-security-header 名稱的原則,便會忽略棄用的表頭。舊版本只理解棄用的名稱,因此,要實現預期支援,回應必須包含具有這三個名稱的相同原則。
- 如果在表頭的同一實例中重複出現某個指令,則會忽略之後出現的所有該指令。

範例 1:以下 django-csp 配置使用不安全的指令 unsafe-inlineunsafe-eval,以便允許內嵌 Script 和程式碼評估:


...
MIDDLEWARE = (
...
'csp.middleware.CSPMiddleware',
...
)
...
CSP_DEFAULT_SRC = ("'self'", "'unsafe-inline'", "'unsafe-eval'", 'cdn.example.net')
...

Abstract
應用程式未限制瀏覽器讓第三方網站轉譯其內容。
Explanation
允許將您的網站新增到框架會引起安全問題。例如,這可能導致點擊劫持弱點,或允許不希望的跨框架通訊。

依預設,Spring Security 之類的架構包含 X-Frame-Options 標頭,以指示瀏覽器是否應對應用程式進行框架處理。停用或未設定此標頭會導致跨框架相關弱點。

範例 1:以下程式碼會將受 Spring Security 保護的應用程式設定為停用 X-Frame-Options 標頭:

<http auto-config="true">
...
<headers>
...
<frame-options disabled="true"/>
</headers>
</http>

Abstract
內容安全性原則 (CSP) 使用過度許可原則進行配置,會有安全上的風險。
Explanation
內容安全性原則 (CSP) 是一種宣告式安全性標頭,可讓開發人員指定瀏覽器中允許的安全性相關行為,包括可從中擷取內容的位置允許清單。除了程式碼中的輸入驗證和檢查允許清單外,它還提供額外一層的安全性,以防禦重要弱點,例如,Cross-Site Scripting、Clickjacking、Cross-Origin Access 等。但設定不當的標頭無法提供這種額外一層的安全性。該原則藉助於 15 個指令進行定義,其中包括 8 個用於控制資源存取的指令,即:script-srcimg-srcobject-srcstyle_srcfont-srcmedia-srcframe-srcconnect-src。這 8 個指令都將一個來源清單做為值,指定網站可存取的網域,以使用該指令所涵蓋的功能。開發人員可使用萬用字元 * 來指示所有或部分來源。其他來源清單關鍵字 (例如 'unsafe-inline''unsafe-eval') 提供更精細的方式來控制 script 執行,但這些是潛在有害的關鍵字。所有指令都不是強制性的。瀏覽器允許未列示指令的所有來源,或從選用的 default-src 指令衍生值。此外,此標頭的規格隨著時間的推移而不斷演變。在第 23 版之前的 Firefox 和第 10 版之前的 IE 中,其實作為 X-Content-Security-Policy,而在第 25 版之前的 Chrome 中,則實作為 X-Webkit-CSP。兩個名稱都已棄用,取代為現在的標準名稱 Content Security Policy。鑒於指令的數目、兩個棄用的替代名稱,以及對待多次出現之同一標頭和單一標頭中重複指令的方式,開發人員很可能會錯誤地設定此標頭。

在此案例中,使用了過度許可原則 (如 *) 來配置 *-src 指令。

範例 1:以下 django-csp 設定會設定過度許可且不安全的 default-src 指令:


...
MIDDLEWARE = (
...
'csp.middleware.CSPMiddleware',
...
)
...
CSP_DEFAULT_SRC = ("'self'", '*')
...

Abstract
程式會定義過度許可的跨原始來源資源分享 (CORS) 政策。
Explanation
在 HTML5 之前,網頁瀏覽器會強制執行相同來源原則,確保在使用 JavaScript 存取網頁內容時,JavaScript 和網頁來自相同的網域。若不使用相同來源策略 (Same Origin Policy),惡意的網站可使用用戶端的憑證來執行 JavaScript,從其他網站載入敏感的資訊,從中挑選出資訊並將資訊回傳給攻擊者。HTML5 使 JavaScript 可以在定義稱為 Access-Control-Allow-Origin 的新 HTTP 標頭時,存取不同網域間的資料。Web 伺服器可使用此標頭,定義允許使用跨來源要求存取其網域的其他網域。但是,定義標頭時請謹慎小心,因為過度許可的 CORS 原則會允許惡意應用程式以不當方式與受害應用程式通訊,進行導致詐騙、資料竊取、轉送和其他攻擊。

範例 1:以下是使用萬用字元在程式上指定允許應用程式與哪些網域通訊的範例。


Response.AppendHeader("Access-Control-Allow-Origin", "*");


使用 * 做為 Access-Control-Allow-Origin 表頭的值,表示應用程式的資料可以讓在任何網域上執行的 JavaScript 存取。

desc.semantic.python.html5_overly_permissive_cors_policy
Abstract
程式會定義過度許可的 Cross-Origin Resource Sharing (CORS) 政策。
Explanation
在 HTML5 之前,網頁瀏覽器會強制執行相同來源原則,確保在使用 JavaScript 存取網頁內容時,JavaScript 和網頁來自相同的網域。若不使用相同來源策略 (Same Origin Policy),惡意網站可使用用戶端的憑證執行從其他網站載入敏感資訊的 JavaScript,從中挑選資訊,並將資訊回傳給攻擊者。HTML5 使 JavaScript 可以在定義稱為 Access-Control-Allow-Origin 的新 HTTP 標頭時,存取不同網域間的資料。Web 伺服器可使用此標頭,定義允許使用跨來源要求存取其網域的其他網域。但是,定義標頭時請謹慎小心,因為過度許可的 CORS 原則會允許惡意應用程式以不當方式與受害應用程式通訊,進行導致詐騙、資料竊取、轉送和其他攻擊。

範例 1:以下是使用萬用字元指定允許應用程式與哪些網域通訊的範例。


play.filters.cors {
pathPrefixes = ["/some/path", ...]
allowedOrigins = ["*"]
allowedHttpMethods = ["GET", "POST"]
allowedHttpHeaders = ["Accept"]
preflightMaxAge = 3 days
}


使用 * 作為 Access-Control-Allow-Origin 標頭的值,表示應用程式的資料可供在任何網域上執行的 JavaScript 存取。

Abstract
程式發佈了跨文件訊息,但其目標來源過度允許。
Explanation
HTML5 的新功能之一便是跨文件訊息。此功能可允許 Script 將訊息發佈至其他視窗。相應的 API 允許使用者指定目標視窗的來源。但是,指定目標來源時應特別小心,因為過度允許的目標來源會允許惡意指令碼以不適當的方式與受害者視窗通訊,導致欺騙、資料遭竊取、傳遞和其他攻擊。

範例 1:以下範例使用萬用字元來以程式化方式指定要傳送之訊息的目標來源。


WebMessage message = new WebMessage(WEBVIEW_MESSAGE);
webview.postWebMessage(message, Uri.parse("*"));


使用 * 作為目標來源值,代表指令碼會傳送訊息至視窗而不論其來源。

依預設,瀏覽器不會將包含來自 HTTPS 之要求的參照標頭傳送給未加密的 HTTP 連結。不過,如果要求目的地也是 HTTPS,則不論來源為何,都會傳送標頭。開發人員可能將敏感資訊留在 URL 中,這些 URL 會透過參照標頭而洩漏給第三方網站。引入 Referrer-Policy 標頭可控制與參照標頭相關的瀏覽器行為。Unsafe-URL 選項會移除所有限制,並傳送包含每個要求的參照標頭。

範例 1:以下程式碼會將受 Spring Security 保護的應用程式設定為停用預設的保護參照原則:

<http auto-config="true">
...
<headers>
...
<referrer-policy policy="unsafe-url"/>
</headers>
</http>

Abstract
內容安全性原則 (CSP) 是在監視模式下進行設定,因此瀏覽器不會強制執行。
Explanation
內容安全性原則 (CSP) 是一種宣告式安全性標頭,可讓開發人員指示在網頁瀏覽器中轉譯時,允許網站從哪些網域載入內容或起始到哪些網域的連線。除了程式碼中的輸入驗證和檢查允許清單外,它還提供額外一層的安全性,以防禦重要弱點,例如,Cross-Site Scripting、Clickjacking、Cross-Origin Access 等。

Content-Security-Policy-Report-Only 標頭為 Web 應用程式作者和管理員提供了監視安全性原則的功能,而不是強制執行原則。此標頭通常在實驗和/或開發網站的安全性原則時使用。當某原則被視為有效時,您可透過改用 Content-Security-Policy 標頭欄位來強制執行此原則。

範例 1:下列程式碼會在 Report-Only 模式中設定內容安全性原則:

<http auto-config="true">

Abstract
將未經驗證的輸入連結成 URL 可能讓攻擊者覆寫要求參數的值。攻擊者可能可以覆寫現有參數值,注入新的參數或者利用直接接觸得到的變數。
Explanation
HTTP Parameter Pollution (HPP)攻擊包含將編碼的字串限制字元注入其他現有參數。如果 Web 應用程式不能妥當清潔使用者輸入,惡意使用者可能危及應用程式邏輯,執行用戶端或伺服器端的攻擊。經由提交額外參數到網頁應用程式,且如果這些參數的名稱與現有參數相同,網頁應用程式可能以下列其中一種方式反應:

僅可使用第一個參數的資料
可使用最後一個參數的資料
可使用所有參數的資料,並將這些資料串連在一起


例如:
- ASP.NET/IIS 會使用所有出現的參數
- Apache Tomcat 僅使用第一個出現的參數並忽略其他位置出現的參數
- mod_perl/Apache 會將值轉換為一個值陣列

範例 1:根據應用程式伺服器及應用程式本身的邏輯而定,下列要求可能造成驗證系統的混淆,進而允許攻擊者模擬另一位使用者。
http://www.server.com/login.aspx?name=alice&name=hacker

範例 2:以下程式碼使用 HTTP 要求的輸入建立兩個超連結。

...
String lang = Request.Form["lang"];
WebClient client = new WebClient();
client.BaseAddress = url;
NameValueCollection myQueryStringCollection = new NameValueCollection();
myQueryStringCollection.Add("q", lang);
client.QueryString = myQueryStringCollection;
Stream data = client.OpenRead(url);
...


URL: http://www.host.com/election.aspx?poll_id=4567
連結 1:<a href="http://www.host.com/vote.aspx?poll_id=4567&lang=en">英文<a>
連結 2:<a href="http://www.host.com/vote.aspx?poll_id=4567&lang=es">西班牙文<a>

程式設計師沒有考慮到攻擊者可能會提供 lang (例如 en&poll_id=1) 的可能性,然後該攻擊者可能會隨意變更 poll_id

Abstract
將未經驗證的輸入連結成 URL 可能讓攻擊者覆寫要求參數的值。攻擊者可能可以覆寫現有參數值,注入新的參數或者利用直接接觸得到的變數。
Explanation
HTTP Parameter Pollution (HPP)攻擊包含將編碼的字串限制字元注入其他現有參數。如果 Web 應用程式不能妥當清潔使用者輸入,惡意使用者可能危及應用程式邏輯,執行用戶端或伺服器端的攻擊。經由提交額外參數到網頁應用程式,且如果這些參數的名稱與現有參數相同,網頁應用程式可能以下列其中一種方式反應:

僅可使用第一個參數的資料
可使用最後一個參數的資料
可使用所有參數的資料,並將這些資料串連在一起


例如:
- ASP.NET/IIS 會使用所有出現的參數
- Apache Tomcat 僅使用第一個出現的參數並忽略其他位置出現的參數
- mod_perl/Apache 會將值轉換為一個值陣列

範例 1:根據應用程式伺服器及應用程式本身的邏輯而定,下列要求可能造成驗證系統的混淆,進而允許攻擊者模擬另一位使用者。
http://www.server.com/login.php?name=alice&name=hacker

範例 2:以下程式碼使用 HTTP 要求的輸入建立兩個超連結。


<%
...
$id = $_GET["id"];
header("Location: http://www.host.com/election.php?poll_id=" . $id);
...
%>


URL: http://www.host.com/election.php?poll_id=4567
連結 1: <a href="vote.php?poll_id=4567&candidate=white">Vote for Mr. White<a>
連結 2: <a href="vote.php?poll_id=4567&candidate=green">Vote for Mrs. Green<a>

程式設計師尚未考慮到攻擊者可能會提供 poll_id,例如「4567&candidate=green」,然後結果頁面中將含有下列注入的連結,因此 Mrs. Green 將一直由選取第一個參數的應用程式伺服器進行投票。
<a href="vote.php?poll_id=4567&candidate=green&candidate=white">Vote for Mr. White<a>
<a href="vote.php?poll_id=4567&candidate=green&candidate=green">Vote for Mrs. Green<a>

Abstract
指定 HTTP 動詞的安全限制通常可允許比預期更大量的存取。
Explanation
在下列情況下,可使用 HTTP 動詞竄改來略過應用程式的 Authentication 和授權機制:
1) 該應用程式使用列出 HTTP 動詞的安全性控制。
2) 安全性控制無法封鎖未列出的動詞。
3) 應用程式根據 GET 要求或其他任意 HTTP 動詞來更新其狀態。



以下組態將易受 HTTP 動詞篡改的攻擊:

<authorization>
<allow verbs="GET,POST" users="admin"/>
<deny verbs="GET,POST"users="*" />
</authorization>

依預設,.NET Framework 允許所有 HTTP 動詞,因此即使此配置拒絕讓所有使用者存取 GET 和 POST,仍無法防止 HEAD 要求。攻擊者也許可透過以 HEAD 要求替代 GET 或 POST 要求,來執行管理功能。換句話說,此程式碼將滿足上述的條件 1 和 2。接著若要讓 HEAD 請求執行管理功能,則應用程式須依據使用 POST 以外的動詞的要求,來執行指令。

就其核心而言,此弱點是嘗試建立拒絕清單 (指示使用者不可進行之事項的原則) 的結果。拒絕清單很少達成預期的效果。

Abstract
指定 HTTP 動詞的安全限制通常可允許比預期更大量的存取。
Explanation
在下列情況下,可使用 HTTP 動詞竄改來略過應用程式的 Authentication 和授權機制:
1) 該應用程式使用列出 HTTP 動詞的安全性控制。
2) 安全性控制無法封鎖未列出的動詞。
3) 應用程式根據 GET 要求或其他任意 HTTP 動詞來更新其狀態。



多數的 Java EE 執行允許組態中未明確列出的 HTTP 方法。例如,下列安全限制會套用至 HTTP GET 方法,但不會套用至其他 HTTP 動詞:


<security-constraint>
<display-name>Admin Constraint</display-name>
<web-resource-collection>
<web-resource-name>Admin Area</web-resource-name>
<url-pattern>/pages/index.jsp</url-pattern>
<url-pattern>/admin/*.do</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint>
<description>only admin</description>
<role-name>admin</role-name>
</auth-constraint>
</security-constraint>


由於此組態的 <http-method> 標籤中未明確定義如 HEAD 的動詞,因此可透過以 HEAD 要求替代 GET 或 POST 要求,來執行管理功能。為了能讓 HEAD 要求執行管理功能,條件 3 必須適用 - 應用程式必須依據 POST 以外的動詞執行指令。某些網路/應用程式伺服器會接受任意的非標準 HTTP 動詞,並以具有指定 GET 要求的型態回應。若情況為此,攻擊者將可使用要求中的任意動詞,來檢視管理頁面。

例如,典型的用戶端 GET 要求範例如下:

GET /admin/viewUsers.do HTTP/1.1
Host: www.example.com


在 HTTP 動詞竄改攻擊中,攻擊者會以與 FOO 同類的要求替代 GET。

FOO /admin/viewUsers.do HTTP/1.1
Host: www.example.com


就其核心而言,此弱點是嘗試建立拒絕清單 (指示使用者不可進行之事項的原則) 的結果。拒絕清單很少達成預期的效果。

Abstract
某些函數會傳回要搜尋之緩衝區邊界以外的記憶體指標。後續操作指標可能會產生意想不到的結果。
Explanation
在以下任一情況下,在緩衝區內搜尋字元的函數,可傳回緩衝區邊界以外的指標:

- 使用者控制了要搜尋的緩衝區內容。

- 使用者控制了要搜尋的值。

範例 1:以下的簡短程式將一個不受信任的指令行引數作為呼叫 rawmemchr() 時的搜尋緩衝區。


int main(int argc, char** argv) {
char* ret = rawmemchr(argv[0], 'x');
printf("%s\n", ret);
}


這個程式本來是要顯示出 argv[0] 的子字串,但是程式可能會以顯示 argv[0] 之前的部分記憶體的方式結束。

這個問題類似於「字串終止錯誤」,程式設計師是依賴字元陣列來包含一個 Null 結束字元。

應用程式允許安裝第三方鍵盤延伸。
Explanation
允許鍵盤延伸讀取使用者輸入的每個單一按鍵輸入。通常使用第三方鍵盤來簡化文字輸入或新增其他 Emoji,它們可能會記錄使用者輸入的內容,甚至將其傳送至遠端伺服器進行處理。還可能會散佈惡意鍵盤作為鍵盤記錄木馬程式,讀取使用者輸入的每個金鑰值,以竊取諸如憑證或信用卡號等敏感資料。

1. 機密資料儲存在記憶體中。

2. 藉由覆寫記憶體內容的方式,來從記憶體清除機密資料。



3. 來源程式碼藉由使用最佳化編譯器來編譯,其會將覆蓋相關內容的函數做為一個無效儲存識別出來並進行移除,因為記憶體之後不會使用這個儲存。
範例 1:以下程式碼會從使用者讀取密碼、使用此密碼連線到後端主機,然後嘗試使用 memset() 來清除記憶體中的密碼。


void GetData(char *MFAddr) {
char pwd[64];
if (GetPasswordFromUser(pwd, sizeof(pwd))) {
if (ConnectToMainframe(MFAddr, pwd)) {
// Interaction with mainframe
}
}
memset(pwd, 0, sizeof(pwd));
}


如果範例中的程式碼被逐字地執行,那麼它就能正確地執行;但如果程式碼是使用最佳化編譯器進行編譯 (如 Microsoft Visual C++(R) .NET 或者 GCC 3.x),那麼 memset() 的呼叫會被當作一個無效儲存清除,因為 pwd 的緩衝區在它的數值被覆蓋之後不會再次被使用 [2]。因為緩衝區 pwd 包含一個敏感值,所以如果資料經常被留在記憶體中,應用程式就會容易受到攻擊。如果攻擊者能夠存取記憶體正確的區域,他們就能使用復原後的密碼來取得對系統的控制。

為了防止攻擊者得到系統的機密,覆蓋記憶體中操作的敏感資料 (如密碼或密鑰) 是種常見的作法。然而,隨著最佳化編譯器的到來,程式不會一直如指示的那樣僅僅按照來源程式碼執行。在此範例中,因為 memset() 的呼叫被寫入記憶體之後不會被使用,所以編譯器將這個呼叫解譯為一段 Dead Code;而這樣做實際上很顯然會引起一個安全問題。這裏的問題是,許多編譯器和許多程式語言並沒有在其提高效率時考慮到此問題和其他安全問題。

攻擊者通常會使用核心傾印或執行期間機制來利用這種類型的弱點,藉此存取某個特定的應用程式所使用的記憶體,並恢復機密資訊。一旦攻擊者存取到機密資訊,盜取更多的系統資訊就相對簡單了,並有可能危及到這個應用程式涉及到的其他資源。

Abstract
可能會錯誤地最佳化陣列邊界。
Explanation
若陣列邊界檢查需要計算違反規定的指標並確定指標已超出邊界,某些編譯器會最佳化該檢查,並認定程式設計師絕不會蓄意建立違反規定的指標。

範例 1:

char *buf;
int len;
...
len = 1<<30;

if (buf+len < buf) //wrap check
[handle overflow]


運算 buf + len 大於 2^32,因此產生的值小於 buf。但是,由於指標的算數運算溢位是未定義的行為,因此某些編譯器會假設 buf + len >= buf,並最佳化封裝檢查。此最佳化操作的結果是,此區塊後的程式碼很容易出現 Buffer overflow。

Abstract
應用程式包含一個並非專用於在生產環境中部署的元件。
Explanation
Django 應用程式會暴露 static files 應用程式的 serve 視圖,此視圖並非專用於在生產環境中部署。根據 Django 說明文件:

static files 工具主要用於協助取得已在生產中成功部署的靜態檔案。這通常是指單獨、專用的靜態檔案伺服器,於本機開發時,此伺服器的運作成本極高。因此,靜態檔案應用程式隨附臨時應急的協助程式視圖,用來在開發期間於本機執行檔案。

僅當 DEBUGTrue 時,此視圖才有效。

這是因為,此視圖非常低效且可能不安全。這僅適用於本機開發,絕不能用於生產中。」

Abstract
針對敏感資源使用可預測的名稱有助於攻擊者展開應用程式探索程序。
Explanation
包含敏感資訊或提供具有特殊權限的功能的應用程式資源通常面臨更大的攻擊風險。在偵察階段,攻擊者會嘗試尋找此類檔案和目錄。針對此類資源使用可預測的命名架構會讓攻擊者更容易找到這些資源。處理敏感功能 (例如,驗證、管理工作或私人資訊處理) 的所有應用程式資源都必須得到充分保護,以免被發現。

範例 1:在以下範例中,admin 應用程式部署在可預測的 URL 中:


from django.conf.urls import patterns
from django.contrib import admin

admin.autodiscover()

urlpatterns = patterns('',
...
url(r'^admin/', include(admin.site.urls)),
...


負責儲存資料的資源必須與實作應用程式功能的資源分開。程式設計師必須在建立暫存或備份資源時小心謹慎。
