OpenCFP Framework (Sentry) Account takeover via null password reset codes
OpenCFP's third-party authentication framework, Sentry, has a vulnerability in versions prior to 2.1.7 where the password reset code defaults to NULL if no token is set. This flaw allows an attacker to manipulate any user's password if they can correlate user IDs with email addresses, potentially enabling account takeover. The vulnerability affects the reset password logic and is rated high severity.
AI Analysis
Technical Summary
The vulnerability in Cartalyst's Sentry authentication framework used by OpenCFP arises from how password reset tokens are handled. When a user lacks a password reset token, the reset_password_code field in the database is NULL. The system's password reset verification does not properly handle this NULL value, allowing an attacker to reset passwords without a valid token. Exploitation requires knowledge of the numeric user ID and corresponding email address, which may be easier for early user IDs (e.g., organizers). This can lead to unauthorized password changes and account takeover. The issue affects versions of Sentry prior to 2.1.7.
Potential Impact
Successful exploitation allows an attacker to reset the password of any OpenCFP user without possessing a valid password reset token, leading to account takeover. This compromises confidentiality and integrity of user accounts, with limited availability impact. The vulnerability is rated high severity due to the potential for full account compromise.
Mitigation Recommendations
A fix is available in Sentry version 2.1.7 and later. Users should upgrade to version 2.1.7 or above to remediate this vulnerability. No other mitigation steps are indicated in the provided data.
