Technical details
IBM Operations Analytics - Log Analysis is vulnerable to improper authentication due to weak password requirements (CWE-521) and inadequate account lockout mechanisms in its Backend Authentication and Session Management module. The vulnerability exists when using the default database-managed custom user registry. While the attack complexity is rated as high, a remote attacker can exploit these weak defaults to perform brute-force or credential-guessing attacks to gain unauthorized access to user accounts. No official patch is currently available; however, IBM recommends migrating to an LDAP user registry to enforce more robust authentication policies.
