CVE-2024-47877Network attack vector

Filesystem link creation via unchecked archive symlinks

Published Oct 11, 2024 · Updated Oct 11, 2024

Path traversal in Codeclysm Extract before 4.0.0 allows remote attackers to create symlinks outside the archive extraction directory. Tar and ZIP extraction accepts archive-supplied link targets and creates links without resolving the link chain and confirming that its destination remains beneath the requested output path. A consuming application must pass an attacker-controlled archive to the library; exploitation writes a filesystem link outside the intended extraction tree.
