AI-suggested
- Implement immediate session ID regeneration upon user authentication to prevent session fixation.
- Review and update session management logic to ensure session IDs cannot be set or fixed before login.
- Enforce secure cookie attributes such as HttpOnly, Secure, and SameSite to reduce session theft risks.
- Monitor web server and application logs for suspicious session activity or repeated session ID usage.
- Educate users to avoid clicking on suspicious links that could set malicious session IDs.
- If possible, upgrade to a newer Quick.Cart version once the vendor releases a patch addressing this vulnerability.
- Employ Web Application Firewalls (WAFs) with custom rules to detect and block session fixation attempts.
- Conduct penetration testing focused on session management to identify and remediate similar issues.
- Limit session lifetime and implement inactivity timeouts to reduce window of exploitation.
- Maintain an incident response plan to quickly address any detected session hijacking incidents.
Description
Quick.Cart allows a user's session identifier to be set before authentication. The value of this session ID stays the same after authentication. This behaviour enables an attacker to fix a session ID for a victim and later hijack the authenticated session. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.7 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.
