LDAP injection is a type of web application security vulnerability that allows an attacker to manipulate a Light Directory Access Protocol (LDAP) server. This is usually done by submitting specially crafted input to an application, which is then used to construct an LDAP query. The attacker's goal is to inject malicious data into the LDAP query, allowing them to bypass authentication, access sensitive data, or perform other unauthorized actions.

LDAP injection typically occurs when an application does not properly validate user input or filters it incorrectly, allowing malicious data to be injected into the LDAP query. This can happen in a variety of ways, including through web forms, URL parameters, or other user-supplied data.

An attacker may use various techniques to inject malicious data into an LDAP query, such as entering specially crafted LDAP search filters, modifying attribute values, or even injecting arbitrary code into the LDAP query. The consequences of LDAP injection can be significant, including unauthorized access to sensitive data, disruption of business operations, and potential financial loss.

To prevent LDAP injection, it is essential for developers to follow secure coding practices, such as validating and sanitizing user input, using prepared statements or parameterized queries, and implementing proper error handling and logging mechanisms. Applications should also be designed to handle exceptions and errors in a secure manner, preventing attackers from extracting sensitive information through error messages.

By understanding the risks and vulnerabilities associated with LDAP injection, organizations can take proactive steps to prevent this type of attack and protect their sensitive data and systems.
