Gemalto Tokend 2013 has an Arbitrary File Creation/Overwrite 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.

An issue was discovered in certain Apple products. iOS before 10.1 is affected. macOS before 10.12.1 is affected. tvOS before 10.0.1 is affected. watchOS before 3.1 is affected. The issue involves the "libarchive" component, which allows remote attackers to write to arbitrary files via a crafted archive containing a symlink.

This issue was addressed with improved validation of symlinks. This issue is fixed in macOS Ventura 13.7.5, macOS Sequoia 15.4, macOS Sonoma 14.7.5. A path handling issue was addressed with improved validation.

crontab.c in crontab in FreeBSD and Apple Mac OS X allows local users to (1) determine the existence of arbitrary files via a symlink attack on a /tmp/crontab.XXXXXXXXXX temporary file and (2) perform MD5 checksum comparisons on arbitrary pairs of files via two symlink attacks on /tmp/crontab.XXXXXXXXXX temporary files.

An issue was discovered in certain Apple products. iOS before 10.3.2 is affected. macOS before 10.12.5 is affected. The issue involves the "iBooks" component. It allows attackers to execute arbitrary code in a privileged context via a crafted app that uses symlinks.

A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v0.9.8 beta (build 02099) for macOS could allow an authenticated, local attacker to overwrite arbitrary files. When the client initiates a connection, the XML /tmp/pia-watcher.plist file is created. If the file exists, it will be truncated and the contents completely overwritten. This file is removed on disconnect. An unprivileged user can create a hard or soft link to arbitrary files owned by any user on the system, including root. This creates a denial of service condition and possible data loss if leveraged by a malicious local user.

When resolving a symlink such as <code>file:///proc/self/fd/1</code>, an error message may be produced where the symlink was resolved to a string containing unitialized memory in the buffer. <br>*This bug only affects Thunderbird on Unix-based operated systems (Android, Linux, MacOS). Windows is unaffected.*. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107.

A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v82 for Linux and macOS could allow an authenticated, local attacker to overwrite arbitrary files. The openvpn_launcher binary is setuid root. This binary supports the --log option, which accepts a path as an argument. This parameter is not sanitized, which allows a local unprivileged user to overwrite arbitrary files owned by any user on the system, including root. This creates a denial of service condition and possible data loss if leveraged by a malicious local user.

This issue is fixed in Security Update 2021-005 Catalina, iOS 14.8 and iPadOS 14.8, iOS 15 and iPadOS 15, watchOS 8, macOS Big Sur 11.6. An application may be able to access restricted files.

Git is an open source, scalable, distributed revision control system. Versions prior to 2.30.6, 2.31.5, 2.32.4, 2.33.5, 2.34.5, 2.35.5, 2.36.3, and 2.37.4 are subject to exposure of sensitive information to a malicious actor. When performing a local clone (where the source and target of the clone are on the same volume), Git copies the contents of the source's `$GIT_DIR/objects` directory into the destination by either creating hardlinks to the source contents, or copying them (if hardlinks are disabled via `--no-hardlinks`). A malicious actor could convince a victim to clone a repository with a symbolic link pointing at sensitive information on the victim's machine. This can be done either by having the victim clone a malicious repository on the same machine, or having them clone a malicious repository embedded as a bare repository via a submodule from any source, provided they clone with the `--recurse-submodules` option. Git does not create symbolic links in the `$GIT_DIR/objects` directory. The problem has been patched in the versions published on 2022-10-18, and backported to v2.30.x. Potential workarounds: Avoid cloning untrusted repositories using the `--local` optimization when on a shared machine, either by passing the `--no-local` option to `git clone` or cloning from a URL that uses the `file://` scheme. Alternatively, avoid cloning repositories from untrusted sources with `--recurse-submodules` or run `git config --global protocol.file.allow user`.

An issue was discovered in Samsung Magician 8.0.0 on macOS. Because symlinks are used during the installation process, an attacker can escalate privileges via arbitrary file permission writes. (The attacker must already have user privileges, and an administrator password must be entered during the program installation stage for privilege escalation.)

Adobe Creative Cloud Desktop Application versions 5.1 and earlier have a symlink vulnerability vulnerability. Successful exploitation could lead to privilege escalation.

Adobe Creative Cloud Desktop Application versions 5.1 and earlier have a symlink vulnerability vulnerability. Successful exploitation could lead to arbitrary file system write.

rubyzip gem rubyzip version 1.2.1 and earlier contains a Directory Traversal vulnerability in Zip::File component that can result in write arbitrary files to the filesystem. This attack appear to be exploitable via If a site allows uploading of .zip files , an attacker can upload a malicious file that contains symlinks or files with absolute pathnames "../" to write arbitrary files to the filesystem..

In Apache Hadoop, The unTar function uses unTarUsingJava function on Windows and the built-in tar utility on Unix and other OSes. As a result, a TAR entry may create a symlink under the expected extraction directory which points to an external directory. A subsequent TAR entry may extract an arbitrary file into the external directory using the symlink name. This however would be caught by the same targetDirPath check on Unix because of the getCanonicalPath call. However on Windows, getCanonicalPath doesn't resolve symbolic links, which bypasses the check. unpackEntries during TAR extraction follows symbolic links which allows writing outside expected base directory on Windows. This was addressed in Apache Hadoop 3.2.3

The combination of primitives offered by SMB and AFP in their default configuration allows the arbitrary writing of files. By exploiting these combination of primitives, an attacker can execute arbitrary code.

An issue was discovered in G-Data before 25.5.9.25 using Symbolic links, it is possible to abuse the infected-file restore mechanism to achieve arbitrary write that leads to elevation of privileges.

The decompress package before 4.2.1 for Node.js is vulnerable to Arbitrary File Write via ../ in an archive member, when a symlink is used, because of Directory Traversal.

Windows System Assessment Tool Elevation of Privilege Vulnerability

Visual Studio Elevation of Privilege Vulnerability

Windows Server Update Service (WSUS) Elevation of Privilege Vulnerability

In Helm 2.x before 2.15.2, commands that deal with loading a chart as a directory or packaging a chart provide an opportunity for a maliciously designed chart to include sensitive content such as /etc/passwd, or to execute a denial of service (DoS) via a special file such as /dev/urandom, via symlinks. No version of Tiller is known to be impacted. This is a client-only issue.

Pedestal Software Integrity Protection Driver (IPD) 1.3 and earlier allows privileged attackers, such as rootkits, to bypass file access restrictions to the Windows kernel by using the NtCreateSymbolicLinkObject function to create a symbolic link to (1) \Device\PhysicalMemory or (2) to a drive letter using the subst command.

This improper link resolution vulnerability allows remote attackers to access system files. To fix this vulnerability, QNAP recommend updating QTS to their latest versions.

The container package in MikroTik RouterOS 7.4beta4 allows an attacker to create mount points pointing to symbolic links, which resolve to locations on the host device. This allows the attacker to mount any arbitrary file to any location on the host.
