CWE-65

Windows Hard Link

Category: VariantCVE: 6
Description

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.

Extended Description

Failure for a system to check for hard links can result in vulnerability to different types of attacks. For example, an attacker can escalate their privileges if a file used by a privileged program is replaced with a hard link to a sensitive file (e.g. AUTOEXEC.BAT). When the process opens the file, the attacker can assume the privileges of that process, or prevent the program from accurately processing data.

CVE-2020-6013

ZoneAlarm Firewall and Antivirus products before version 15.8.109.18436 allow an attacker who already has access to the system to execute code at elevated privileges through a combination of file permission manipulation and exploitation of Windows CVE-2020-00896 on unpatched systems.

CVE-2022-23742

Check Point Endpoint Security Client for Windows versions earlier than E86.40 copy files for forensics reports from a directory with low privileges. An attacker can replace those files with malicious or linked content, such as exploiting CVE-2020-0896 on unpatched systems or using symbolic links.

CVE-2019-8452

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.

CVE-2019-8455

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.

HIGH
CVE-2019-8454

A local attacker can create a hard-link between a file to which the Check Point Endpoint Security client for Windows before E80.96 writes and another BAT file, then by impersonating the WPAD server, the attacker can write BAT commands into that file that will later be run by the user or the system.
