A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability, which was classified as problematic, was found in zt-zip up to 1.12. Affected is an unknown function of the component Extraction. The manipulation with the input value ../ leads to a path traversal vulnerability (Zip-Slip). CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on integrity, and availability. CVE summarizes:

zt-zip before 1.13 is vulnerable to directory traversal, allowing attackers to write to arbitrary files via a ../ (dot dot slash) in a Zip archive entry that is mishandled during extraction. This vulnerability is also known as 'Zip-Slip'.

The bug was discovered 04/13/2018. The weakness was presented 07/25/2018 (GitHub Repository). The advisory is available at github.com. This vulnerability is traded as CVE-2018-1002201 since 07/25/2018. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.

The vulnerability was handled as a non-public zero-day exploit for at least 103 days. During that time the estimated underground price was around $0-$5k.

Upgrading to version 1.13 eliminates this vulnerability.
