Description
Users were able to set an arbitrary "product name" for OX Guard. The chosen value was not sufficiently sanitized before processing it at the user interface, allowing for indirect cross-site scripting attacks. Accounts that were temporarily taken over could be configured to trigger persistent code execution, allowing an attacker to build a foothold. Sanitization is in place for product names now. No publicly available exploits are known.
