medium Nessus Plugin ID 63826

Language:

Synopsis

The remote AIX host is missing a security patch.

Description

After installing bos.rte.security 6.1.6.4 fileset, an LDAP user will be able to log in with an incorrect password. This occurs only when authtype is set to ldap_auth in the /etc/security/ldap/ldap.cfg file.
Non-LDAP users can also log in with incorrect passwords if the local users have their SYSTEM attribute in the /etc/security/user file is set to SYSTEM = 'LDAP', or the default stanza is set to SYSTEM = 'LDAP' and local users do not have SYSTEM set in their own stanza. If local users don't have LDAP in their SYSTEM attribute, then they will not be affected.

Solution

Install the appropriate interim fix.
