How the mentioned CVE works:
The vulnerability exists within the Ibexa user login mechanism. When an invalid login attempt is made, the system returns different error messages depending on whether the submitted username corresponds to a valid user account. An attacker can exploit this by systematically submitting login requests with various usernames and analyzing the error responses. If the message for an invalid username differs from the message for a valid username with an incorrect password, the attacker can determine which accounts are registered in the system. This user enumeration flaw weakens authentication security by revealing sensitive information, paving the way for targeted brute-force attacks.
