| Titel | Formalms FormaLMS 4.1.18 Information Exposure Through Discrepancy |
|---|
| Beschreibung | A user enumeration vulnerability exists in FormaLMS (4.1.18 and below) in the password recovery functionality accessible via the /lostpwd endpoint. The application returns different error messages for valid and invalid usernames (e.g., "The username you've inserted doesn't exist. Please check and retry." for non-existent users), allowing an unauthenticated attacker to determine which usernames are registered in the system through observable response discrepancy (CWE-204). This information can be leveraged to conduct targeted brute-force or credential stuffing attacks. |
