Privilege Escalation vulnerability in McAfee MVISION Endpoint prior to 20.9 Update allows local users to access files which the user otherwise would not have access to via manipulating symbolic links to redirect McAfee file operations to an unintended file.

Insufficient data validation in installer in Google Chrome prior to 86.0.4240.183 allowed a local attacker to potentially elevate privilege via a crafted filesystem.

In netdiag, there is a possible symbolic link following due to an improper link resolution. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS06308877; Issue ID: ALPS06308877.

An issue was discovered in Icinga2 before v2.12.0-rc1. The prepare-dirs script (run as part of the icinga2 systemd service) executes chmod 2750 /run/icinga2/cmd. /run/icinga2 is under control of an unprivileged user by default. If /run/icinga2/cmd is a symlink, then it will by followed and arbitrary files can be changed to mode 2750 by the unprivileged icinga2 user.

atop: symlink attack possible due to insecure tempfile handling

Avira Antivirus before 5.0.2003.1821 on Windows allows privilege escalation or a denial of service via abuse of a symlink.

ESET Antivirus and Antispyware Module module 1553 through 1560 allows a user with limited access rights to create hard links in some ESET directories and then force the product to write through these links into files that would normally not be write-able by the user, thus achieving privilege escalation.

It was found that versions of rpm before 4.13.0.2 use temporary files with predictable names when installing an RPM. An attacker with ability to write in a directory where files will be installed could create symbolic links to an arbitrary location and modify content, and possibly permissions to arbitrary files, which could be used for denial of service or possibly privilege escalation.

An issue existed within the path validation logic for symlinks. This issue was addressed with improved path sanitization. This issue is fixed in macOS Big Sur 11.0.1, iOS 14.2 and iPadOS 14.2, tvOS 14.2, watchOS 7.1. A local attacker may be able to elevate their privileges.

An elevation of privilege vulnerability exists in the way the Update Notification Manager handles files.To exploit this vulnerability, an attacker would first have to gain execution on the victim system, aka 'Update Notification Manager Elevation of Privilege Vulnerability'.

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.

sosreport in SoS 3.x allows local users to obtain sensitive information from sosreport files or gain privileges via a symlink attack on an archive file in a temporary directory, as demonstrated by sosreport-$hostname-$date.tar in /tmp/sosreport-$hostname-$date.

Location Framework in Apple iOS before 8.4.1 allows local users to bypass intended restrictions on filesystem modification via a symlink.

In open buildservice 2.6 before 2.6.3, 2.5 before 2.5.7 and 2.4 before 2.4.8 the source service patch application could generate non-standard files like symlinks or device nodes, which could allow buildservice users to break of confinement or cause denial of service attacks on the source service.

Western Digital My Cloud OS 5 devices before 5.10.122 mishandle Symbolic Link Following on SMB and AFP shares. This can lead to code execution and information disclosure (by reading local files).

Improper privileges management vulnerability in McAfee Endpoint Security (ENS) Windows prior to 10.7.0 September 2021 Update allows local users to access files which they would otherwise not have access to via manipulating junction links to redirect McAfee folder operations to an unintended location.

Windows User Profile Service Elevation of Privilege Vulnerability

Windows Event Tracing Elevation of Privilege Vulnerability

Privilege Escalation vulnerability in the File Lock component of McAfee Total Protection (MTP) prior to 16.0.32 allows a local user to gain elevated privileges by manipulating a symbolic link in the IOCTL interface.

This affects the package juce-framework/JUCE before 6.1.5. This vulnerability is triggered when a malicious archive is crafted with an entry containing a symbolic link. When extracted, the symbolic link is followed outside of the target dir allowing writing arbitrary files on the target host. In some cases, this can allow an attacker to execute arbitrary code. The vulnerable code is in the ZipFile::uncompressEntry function in juce_ZipFile.cpp and is executed when the archive is extracted upon calling uncompressTo() on a ZipFile object.

Symbolic link manipulation vulnerability in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 February 2020 Update allows authenticated local user to potentially gain an escalation of privileges by pointing the link to files which the user which not normally have permission to alter via carefully creating symbolic links from the ENS log file directory.

Symantec Endpoint Protection, prior to 14.3, may not respect file permissions when writing to log files that are replaced by symbolic links, which can lead to a potential elevation of privilege.
