The tar-rs library versions 0.4.44 and below contain a symlink-following vulnerability in the unpack_dir function that allows attackers to modify permissions on arbitrary directories outside the extraction root. An attacker can craft a malicious tarball containing a symlink entry followed by a directory entry with the same name; when unpacked, the library follows the symlink and applies chmod to the target directory rather than validating it resides within the extraction root. This vulnerability has a CVSS score of 5.1 with network accessibility and low attack complexity, making it exploitable by remote attackers without privileges or special user interaction beyond accepting a crafted archive.
An issue was discovered in the tar crate before 0.4.36 for Rust. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
The npm package "tar" (aka node-tar) before versions 6.1.1, 5.0.6, 4.4.14, and 3.3.2 has a arbitrary File Creation/Overwrite vulnerability due to insufficient absolute path sanitization. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Path Traversal vulnerability could allow attackers to access files and directories outside the intended path.
The npm package "tar" (aka node-tar) before versions 6.1.2, 5.0.7, 4.4.15, and 3.2.3 has an arbitrary File Creation/Overwrite vulnerability via insufficient symlink protection. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Path Traversal vulnerability could allow attackers to access files and directories outside the intended path.
