CVE-2025-3445

CVE-2025-3445: mholt/archiver Vulnerable to Path Traversal via Crafted ZIP File

A Path Traversal "Zip Slip" vulnerability has been identified in mholt/archiver in Go. This vulnerability allows using a crafted ZIP file containing path traversal symlinks to create or overwrite files with the user's privileges or application utilizing the library.

When using the archiver.Unarchive functionality with ZIP files, like this: archiver.Unarchive(zipFile, outputDir), A crafted ZIP file can be extracted in such a way that it writes files to the affected system with the same privileges as the application executing this vulnerable functionality. Consequently, sensitive files may be overwritten, potentially leading to privilege escalation, code execution, and other severe outcomes in some cases.

It's worth noting that a similar vulnerability was found in TAR files (CVE-2024-0406). Although a fix was implemented, it hasn't been officially released, and the affected project has since been deprecated. The successor to mholt/archiver is a new project called mholt/archives, and its initial release (v0.1.0) removes the Unarchive() functionality.

Root Cause Analysis

The vulnerability description directly implicates archiver.Unarchive as the function processing the malicious input (crafted ZIP file) and performing the unsafe extraction. The provided commit, although only a README update, confirms the project's stance on not mitigating this specific vulnerability within its extraction functionalities. The deprecation of the project and removal of Unarchive() in its successor further supports that this function was the core of the issue. While the exact file path for archiver.go is an assumption based on common Go project structures and the function name, the function signature archiver.Unarchive is clearly identified as vulnerable.
