ProFTPD before 1.3.5e and 1.3.6 before 1.3.6rc5 controls whether the home directory of a user could contain a symbolic link through the AllowChrootSymlinks configuration option, but checks only the last path component when enforcing AllowChrootSymlinks. Attackers with local access could bypass the AllowChrootSymlinks control by replacing a path component (other than the last one) with a symbolic link. The threat model includes an attacker who is not granted full filesystem access by a hosting provider, but can reconfigure the home directory of an FTP user.

A flaw was found in chrony versions before 3.5.1 when creating the PID file under the /var/run/chrony folder. The file is created during chronyd startup while still running as the root user, and when it's opened for writing, chronyd does not check for an existing symbolic link with the same file name. This flaw allows an attacker with privileged access to create a symlink with the default PID file name pointing to any destination file in the system, resulting in data loss and a denial of service due to the path traversal.

A local authenticated malicious user with low privileges potentially could exploit this vulnerability to delete arbitrary files by creating a symlink from the "Temp\ICProgress\Dell_InventoryCollector_Progress.xml" to any targeted file. This issue occurs because permissions on the Temp directory were set incorrectly.

An issue was discovered in certain Apple products. iOS before 10.3 is affected. macOS before 10.12.4 is affected. tvOS before 10.2 is affected. watchOS before 3.2 is affected. The issue involves symlink mishandling in the "libarchive" component. It allows local users to change arbitrary directory permissions via unspecified vectors.

Windows Print Spooler Elevation of Privilege Vulnerability

ROG Live Service’s function for deleting temp files created by installation has an improper link resolution before file access vulnerability. Since this function does not validate the path before deletion, an unauthenticated local attacker can create an unexpected symbolic link to system file path, to delete arbitrary system files and disrupt system service.

Improper Link Resolution Before File Access ('Link Following') vulnerability in the EPAG component of Bitdefender Endpoint Security Tools for Windows allows a local attacker to cause a denial of service. This issue affects: Bitdefender GravityZone version 7.1.2.33 and prior versions.

Dell SupportAssist Client Consumer versions 3.9.13.0 and any versions prior to 3.9.13.0 contain an arbitrary file deletion vulnerability that can be exploited by using the Windows feature of NTFS called Symbolic links. Symbolic links can be created by any(non-privileged) user under some object directories, but by themselves are not sufficient to successfully escalate privileges. However, combining them with a different object, such as the NTFS junction point allows for the exploitation. Support assist clean files functionality do not distinguish junction points from the physical folder and proceeds to clean the target of the junction that allows nonprivileged users to create junction points and delete arbitrary files on the system which can be accessed only by the admin.

An elevation of privilege vulnerability exists when the Windows User Profile Service (ProfSvc) improperly handles symlinks, aka 'Windows User Profile Service Elevation of Privilege Vulnerability'.

An issue was discovered in certain Apple products. iOS before 10.2 is affected. macOS before 10.12.2 is affected. watchOS before 3.1.3 is affected. The issue involves the "libarchive" component, which allows local users to write to arbitrary files via vectors related to symlinks.

This allows authenticated users with SCP access to overwrite certain configuration files that would otherwise be restricted.

A local authenticated malicious user with low privileges potentially could exploit this vulnerability to delete arbitrary files by creating a symlink from the "Temp\IC\ICDebugLog.txt" to any targeted file. This issue occurs because of insecure handling of Temp directory permissions that were set incorrectly.
