IBM AIX "secldapclntd" daemon authentication vulnerability

Vulnerability Note VU#624713

Original Release Date: 2003-04-02 | Last Revised: 2003-04-17


A vulnerability in the secldapclntd daemon in IBM's AIX operating system could allow unauthorized remote users to modify accounts on the system.


According to the IBM bulletin for this issue:

"The secldapclntd daemon accepts requests from the LDAP load module, forwards requests to the LDAP server, and passes results from the server back to the LDAP loadmodule. The secldapclntd daemon uses an internet socket to communicate with the loadmodule. A remote user can craft a message to communicate with the daemon and gain unauthorized access to data or could potentially modify user accounts on the LDAP server."

This exposes a vulnerability in environments that use an LDAP (Lightweight Directory Access Protocol) database for user authentication.


A remote attacker can gain unauthorized access to data or modify user accounts on the system. It is unclear whether this vulnerability can be leveraged to gain root or other system-level access to the affected systems.
