init_tmp in TeeJee.FileSystem.vala in Timeshift before 20.03 unsafely reuses a preexisting temporary directory in the predictable location /tmp/timeshift. It follows symlinks in this location or uses directories owned by unprivileged users. Because Timeshift also executes scripts under this location, an attacker can attempt to win a race condition to replace scripts created by Timeshift with attacker-controlled scripts. Upon success, an attacker-controlled script is executed with full root privileges. This logic is practically always triggered when Timeshift runs regardless of the command-line arguments used.

Trendnet AC2600 TEW-827DRU version 2.08B01 contains a symlink vulnerability in the bittorrent functionality. If enabled, the bittorrent functionality is vulnerable to a symlink attack that could lead to remote code execution on the device. If an end user inserts a flash drive with a malicious symlink on it that the bittorrent client can write downloads to, then a user is able to download arbitrary files to any desired location on the devices filesystem, which could lead to remote code execution. Example directories vulnerable to this include "config", "downloads", and "torrents", though it should be noted that "downloads" is the only vector that allows for arbitrary files to be downloaded to arbitrary locations.

GNOME Display Manager (gdm) before 2.21.1 allows local users to change permissions of arbitrary directories via a symlink attack on /tmp/.X11-unix/.

An improper link resolution before file access ('link following') vulnerability exists in the Palo Alto Networks GlobalProtect app on Windows that enables a local attacker to disrupt system processes and potentially execute arbitrary code with SYSTEM privileges under certain circumstances. This issue impacts: GlobalProtect app 5.1 versions earlier than GlobalProtect app 5.1.10 on Windows. GlobalProtect app 5.2 versions earlier than GlobalProtect app 5.2.5 on Windows. This issue does not affect GlobalProtect app on other platforms.

snapd 2.54.2 did not properly validate the location of the snap-confine binary. A local attacker who can hardlink this binary to another location to cause snap-confine to execute other arbitrary binaries and hence gain privilege escalation. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1

cfgcon in IBM AIX 5.2 and 5.3 does not properly validate the argument to the "-p" option to swcons, which allows local users in the system group to create an arbitrary file, and enable world writability of this file, via a symlink attack involving use of the file's name as the argument. NOTE: this issue is due to an incomplete fix for CVE-2007-5804.

The LHA.sys driver before 1.1.1811.2101 in LG Device Manager exposes functionality that allows low-privileged users to read and write arbitrary physical memory via specially crafted IOCTL requests and elevate system privileges. This occurs because the device object has an associated symbolic link and an open DACL.

NVIDIA GeForce Experience before 3.18 contains a vulnerability when ShadowPlay or GameStream is enabled. When an attacker has access to the system and creates a hard link, the software does not check for hard link attacks. This behavior may lead to code execution, denial of service, or escalation of privileges.

An unprivileged user can prepare a symlink at this location to have the file system mounted in an arbitrary location. By winning a race condition, the attacker can also enter the mount point, thereby preventing a subsequent unmount of the file system.
