Vulnerability reported (CVE-2025-34155). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
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.
