Description

OSClass contains a flaw that allows a remote attacker to traverse outside of a restricted path. The issue is due to the oc-content/themes/modern/combine.php script not properly sanitizing user input, specifically directory traversal style attacks (e.g., ../../) supplied when creating cache files. This directory traversal attack would allow the attacker to overwrite or copy arbitrary files.
