CVE-2019-8455
17.04.2019, 15:29
A hard-link created from the log file of Check Point ZoneAlarm up to 15.4.062 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.

Common Weakness Enumeration
- CWE-65 - Windows Hard LinkThe software, 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 software to operate on unauthorized files.
- CWE-59 - Improper Link Resolution Before File Access ('Link Following')The software 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.
