| タイトル | Vichan Devel Vichan 5.1.5 Unverified Password Change |
|---|
| 説明 | An authentication bypass in the password change mechanism (CWE-620) exists in vichan. An authenticated moderator can change their own password without supplying the current password. The application relies solely on an active session and permission checks, without re-authentication or password verification.
If an attacker gains access to a valid moderator session (e.g., via XSS, CSRF, session fixation, or stolen cookies), they can permanently take over the account by changing the password. |
