Executive Summary

This is an authenticated stored cross-site scripting (XSS) vulnerability in the Phoca Gallery Joomla extension versions 4.5.0 to 6.1.5. It allows attackers with valid credentials to inject malicious scripts via HTML attributes, which are then stored and executed when other users view the affected pages.

Impact Analysis

An attacker could steal session cookies, perform actions on behalf of users, or deface the website. Users with access to the Joomla admin panel could exploit this to compromise other users or the entire site.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR and HIPAA requirements for data protection and confidentiality. Organizations may face compliance penalties if user data is compromised through this flaw.

Mitigation Strategies

Update Phoca Gallery to the latest version that patches this vulnerability. If an update is not available, consider disabling the extension until a patch is released. Review user input handling in Joomla configurations to prevent HTML attribute injection.
