CVE-2014-9753Public exploitNetwork attack vector

Account impersonation via unchecked auto-login member ID

Published Feb 11, 2020 · Updated Aug 6, 2024

Improper authentication in ATutor 2.2 and earlier allows remote attackers to impersonate an existing user through confirm.php. An auto_login request accepts an attacker-supplied member_id and sets the application's authenticated session variables after only confirming that the account exists. Knowledge of a user ID is sufficient; the resulting session has that user's privileges, including administrative access when an administrator ID is selected.
