Detailsinfo

A vulnerability, which was classified as critical, was found in squinky86 STIGQter up to 1.2.6. Affected is an unknown code block. The manipulation with an unknown input leads to a path traversal vulnerability. 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 confidentiality, integrity, and availability. CVE summarizes:

STIGQter is an open-source reimplementation of DISA's STIG Viewer. From 0.1.2 to before 1.2.7, an attacker can achieve local code execution (LCE) with the privileges of the user running STIGQter.
