CVE-2025-34155 Details
Description
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.
A user enumeration vulnerability has been identified in Tibbo AggreGate Network Manager versions prior to 6.40.05. The issue arises from an observable response discrepancy in the login process, where authentication failure messages vary depending on the existence of the supplied username.
