執行一個 LDAP 指令，該指令包含了由用戶控制的數值字符串，且使用濾字符串以外的字符，這可能會使攻擊者改變指令的含義或執行非法 LDAP 命令。
LDAP manipulation 錯誤在以下情況中出現：
1. 數據從一個不可信賴的數據源進入程序。
2. 數據在一個動態 LDAP 指令的濾字符串之外使用。
例 1：以下代碼從一個 HTTP 請求里讀取用戶名和密碼，并且使用它去執行 LDAP 查詢。
env.put(Context.SECURITY_AUTHENTICATION, "none");
DirContext ctx = new InitialDirContext(env);
String empID = request.getParameter("empID");
try
{
BasicAttribute attr = new BasicAttribute("empID", empID);
NamingEnumeration employee =
ctx.search("ou=People,dc=example,dc=com",attr);
