Name of the Vulnerable Software and Affected Versions OrdaSoft Joomla Gallery versions prior to 6.2.7
Description An authenticated user with core.manage privileges can achieve remote code execution. The saveWatermark() function copies uploaded files into a web-accessible directory using the client-supplied filename without performing extension checks, content verification, or filename sanitization. This allows an attacker to upload a .php file by disguising it with an image Content-Type header and subsequently execute it by requesting the file path.
Recommendations Update OrdaSoft Joomla Gallery to version 6.2.7 or later. As a temporary mitigation, restrict access to the saveWatermark() function for users with core.manage privileges until the update is applied.
