軟體安全性並非安全性軟體。我們關注驗證、Access Control、保密性、加密以及權限管理之類的主題。

Access Control: Anonymous LDAP Bind

Abstract
若沒有適當的 Access Control,執行包含使用者控制值的 LDAP 指令,可讓攻擊者查看未經授權的記錄。
Explanation
若未經 authentication 便在匿名連結下有效地執行 LDAP 查詢,會讓攻擊者濫用低階配置的 LDAP 環境。

範例 1:以下程式碼使用匿名連結建立 DirectoryEntry de


...
de = new DirectoryEntry("LDAP://ad.example.com:389/ou=People,dc=example,dc=com");
...


所有針對 de 的 LDAP 查詢會在未經 authentication 和 access control 的情況下執行。攻擊者可能會以意想不到的方式來操縱其中的一個查詢,以取得原本應受目錄的 access control 機制所保護的記錄。

Abstract
若沒有適當的 Access Control,執行包含使用者控制之值的 LDAP 陳述式可讓攻擊者存取未經授權的記錄。
Explanation
在匿名繫結下執行 LDAP 查詢,可讓攻擊者在未經驗證的情況下有效濫用配置不當的 LDAP 環境。

範例 1:如果使用者輸入空白密碼,以下程式碼將會建立匿名繫結。


...
$ldapbind = ldap_bind ($ldap, $dn, $password = "" );
...


透過此連線執行的所有後續 LDAP 查詢,就可以在沒有驗證和 Access Control 之下直接執行。攻擊者可能會以意想不到的方式操縱這些查詢之一,以取得對記錄的存取權,否則這些記錄將受到目錄 Access Control 機制的保護。
