LDAP Injection Testing

Testing for LDAP injection involves manipulating LDAP filter syntax in input fields to identify authentication bypass, privilege escalation, and sensitive data extraction flaws in directory services like Active Directory and OpenLDAP.

LDAP injection is a web application security vulnerability where attackers manipulate LDAP filter syntax to bypass authentication, extract sensitive directory data, or escalate privileges in systems like Active Directory and OpenLDAP.

Authentication bypass is a primary LDAP injection technique. By manipulating filter syntax in login forms, testers can exploit vulnerable web applications interacting with LDAP directory services to gain unauthorized access.

Blind LDAP injection testing requires a solid understanding of the LDAP protocol, filter syntax, and web application security fundamentals to infer data extraction without direct server responses from the directory service.

LDAP injection testing applies to web applications interacting with both Active Directory and OpenLDAP. The techniques target the LDAP filter syntax and protocol standards common across these directory services.

Detection is limited by the tester's knowledge of LDAP protocol and filter syntax. Proper exploitation requires understanding web application security fundamentals and how the target application constructs LDAP queries.
