A hard-link created from log file archive of Check Point ZoneAlarm up to 15.4.062 or Check Point Endpoint Security client for Windows before E80.96 to any file on the system will get its permission changed so that all users can access that linked file. Doing this on files with limited access gains the local attacker higher privileges to the file.
The product, when opening a file or directory, does not sufficiently handle when the name is associated with a hard link to a target that is outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
