Summary

Tibbo AggreGate Network Manager < 6.40.05 contains an observable response discrepancy in its login functionality. Authentication failure messages differ based on whether a supplied username exists or not, allowing an unauthenticated remote attacker to infer valid account identifiers. This can facilitate user enumeration and increase the likelihood of targeted brute-force or credential-stuffing attacks.

Risk Assessment

User enumeration could enable an attacker to conduct targeted brute-force or credential-stuffing attacks, potentially leading to account compromise and system security breach.

Recommendation

Update Tibbo AggreGate Network Manager to version 6.40.05 or later. Standardize login error messages to not reveal account existence.
