Summary

The RemoteUserStoreManagerService does not sufficiently validate password change attempts when the password history validation feature is enabled. This oversight allows an attacker to repeatedly attempt password guesses for a user account without being adequately restricted.

Exploiting this vulnerability enables an attacker to discover a user's password through brute force, leading to account impersonation. The success rate of such an attack is influenced by the complexity of the targeted user's password, with simpler passwords increasing the likelihood of compromise.
