AI-suggested

  1. Immediate upgrade of ChurchCRM installations to version 6.5.3 or later, which contains the fix for this vulnerability.
  2. Review and restrict user permissions to ensure that only trusted users have 'Edit Records' and 'Manage Properties and Classifications' privileges, minimizing the attack surface.
  3. Implement strict input validation and output encoding on all user-supplied data fields, especially those displayed in administrator profiles, to prevent injection of malicious scripts.
  4. Conduct regular audits of user roles and access controls to detect and remediate any unauthorized privilege escalations or misconfigurations.
  5. Monitor logs for unusual profile access or modification activities that could indicate exploitation attempts.
  6. Educate administrators to be cautious when viewing profile pages and to report any suspicious behavior.
  7. Employ Content Security Policy (CSP) headers to reduce the impact of potential XSS payloads by restricting the execution of unauthorized scripts.
  8. Consider implementing multi-factor authentication (MFA) for administrator accounts to mitigate session hijacking risks.
  9. Regularly back up ChurchCRM data and configurations to enable recovery in case of compromise.
  10. Stay informed about updates from ChurchCRM and security advisories to promptly address new vulnerabilities.

Description

ChurchCRM is an open-source church management system. A privilege escalation vulnerability exists in ChurchCRM prior to version 6.5.3. An authenticated user with specific mid-level permissions ("Edit Records" and "Manage Properties and Classifications") can inject a persistent Cross-Site Scripting (XSS) payload into an administrator's profile. The payload executes when the administrator views their own profile page, allowing the attacker to hijack the administrator's session, perform administrative actions, and achieve a full account takeover. This vulnerability is a combination of two separate flaws: an Insecure Direct Object Reference (IDOR) that allows any user to view any other user's profile, and a Broken Access Control vulnerability that allows a user with general edit permissions to modify any other user's record properties. Version 6.5.3 fixes the issue.
