CVE-2025-0981

Session Hijacking via Stored Cross-Site Scripting (XSS) in ChurchCRM GroupEditor.php Description Field

Published Feb 18, 2025 CVSS 4.0 · 8.4 High EPSS < 1% KEV · Not listed
Description
A vulnerability exists in ChurchCRM 5.13.0 and prior that allows an attacker to hijack a user's session by exploiting a Stored Cross Site Scripting (XSS) vulnerability in the Group Editor page. This allows admin users to inject malicious JavaScript in the description field, which captures the session cookie of authenticated users. The cookie can then be sent to an external server, enabling session hijacking. It can also lead to information disclosure, as exposed session cookies can be used to impersonate users and gain unauthorised access to sensitive information.

Remediation

Vendor Solution

To mitigate this vulnerability, implement output encoding to prevent malicious script injection in user-controlled input fields, ensure that session cookies are set with the HttpOnly and Secure flags to protect them from client-side access, and validate and sanitize user input before reflecting it in web pages.
