CVSS v3.1 |
| On Linux, if the target of Root.Chmod is replaced with a symlink while the chmod operation is in progress, Chmod can operate on the target of the symlink, even when the target lies outside the root. The Linux fchmodat syscall silently ignores the AT_SYMLINK_NOFOLLOW flag, which Root.Chmod uses to avoid symlink traversal. Root.Chmod checks its target before acting and returns an error if the target is a symlink lying outside the root, so the impact is limited to cases where the target is replaced with a symlink between the check and operation. |
| Dell Optimizer, versions prior to 6.3.1, contain an Improper Link Resolution Before File Access ('Link Following') vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of Privileges. |
| BentoML is a Python library for building online serving systems optimized for AI apps and model inference. Prior to 1.4.36, the safe_extract_tarfile() function validates that each tar member's path is within the destination directory, but for symlink members it only validates the symlink's own path, not the symlink's target. An attacker can create a malicious bento/model tar file containing a symlink pointing outside the extraction directory, followed by a regular file that writes through the symlink, achieving arbitrary file write on the host filesystem. This vulnerability is fixed in 1.4.36. |
| Gogs is an open source self-hosted Git service. Prior to version 0.14.2, gogs api still accepts tokens in url params like token and access_token, which can leak through logs, browser history, and referrers. This issue has been patched in version 0.14.2. |
| node-tar is a full-featured Tar for Node.js. Prior to version 7.5.10, tar can be tricked into creating a hardlink that points outside the extraction directory by using a drive-relative link target such as C:../target.txt, which enables file overwrite outside cwd during normal tar.x() extraction. This issue has been patched in version 7.5.10. |
| ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, domain="path" authorization is checked before final file open/use. A symlink swap between check-time and use-time bypasses policy-denied read/write. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41. |
| Free of memory not on the heap in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally. |
| Improper link resolution before file access ('link following') in Host Process for Windows Tasks allows an authorized attacker to elevate privileges locally. |
| Intego Personal Backup, a macOS backup utility that allows users to create scheduled backups and bootable system clones, contains a local privilege escalation vulnerability. Backup task definitions are stored in a location writable by non-privileged users while being processed with elevated privileges. By crafting a malicious serialized task file, a local attacker can trigger arbitrary file writes to sensitive system locations, leading to privilege escalation to root. |
| linki.py in ekg 2005-06-05 and earlier allows local users to overwrite or create arbitrary files via a symlink attack on temporary files. |
| Race condition in Java 1.4.2 before 1.4.2 Release 2 on Apple Mac OS X allows local users to corrupt files or create arbitrary files via unspecified attack vectors related to a temporary directory, possibly due to a symlink attack. |
| passwd in Directory Services in Mac OS X 10.3.x before 10.3.9 and 10.4.x before 10.4.5 allows local users to overwrite arbitrary files via a symlink attack on the .pwtmp.[PID] temporary file. |
| GNU Gnump3d before 2.9.8 allows local users to modify or delete arbitrary files via a symlink attack on the index.lok temporary file. |
| 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. |
| ArGoSoft FTP Server 1.2.2.2 allows remote attackers to read arbitrary files and directories by uploading a .lnk (link) file that points to the target file. |
| Transsoft Broker 5.9.5.0 allows remote attackers to read arbitrary files and directories by uploading a .lnk (link) file that points to the target file. |
| htpasswd and htdigest in Apache 2.0a9, 1.3.14, and others allows local users to overwrite arbitrary files via a symlink attack. |
| Eudora 4.x allows remote attackers to bypass the user warning for executable attachments such as .exe, .com, and .bat by using a .lnk file that refers to the attachment, aka "Stealth Attachment." |
| cPanel 9.4.1-RELEASE-64 follows hard links, which allows local users to (1) read arbitrary files via the backup feature or (2) chown arbitrary files via the .htaccess file when Front Page extensions are enabled or disabled. |
| The mysqlaccess script in MySQL 4.0.23 and earlier, 4.1.x before 4.1.10, 5.0.x before 5.0.3, and other versions including 3.x, allows local users to overwrite arbitrary files or read temporary files via a symlink attack on temporary files. |
