Name of the Vulnerable Software and Affected Versions Webgalamb version 7.0

Description The issue arises from the wg7.php file in Webgalamb, which makes opportunistic calls to htmlspecialchars() instead of utilizing a templating engine with proper contextual encoding. This allows for the insertion of arbitrary strings into the database, enabling any JavaScript to be executed by the administrator, resulting in a cross-site scripting (XSS) issue.

Recommendations For Webgalamb version 7.0, consider implementing a templating engine with proper contextual encoding to mitigate the risk of XSS attacks. As a temporary workaround, restrict access to the wg7.php file and ensure that all user input is thoroughly validated and sanitized to prevent malicious string insertion.
