Name of the Vulnerable Software and Affected Versions Tibbo AggreGate Network Manager versions prior to 6.40.05

Description The login functionality exhibits a discrepancy in authentication failure messages. These messages vary depending on whether a provided username exists, potentially enabling an unauthenticated remote attacker to identify valid account identifiers. This can aid in user enumeration, potentially increasing the success rate of brute-force or credential-stuffing attacks. The /login API endpoint is affected. The username parameter is vulnerable to enumeration.

Recommendations Update Tibbo AggreGate Network Manager to version 6.40.05 or later.
