CVE-2026-42881 Details
Description
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. This requires user interaction: the victim must open the malicious .stigqter file and explicitly run the "Export HTML" action. This vulnerability is fixed in 1.2.7.
A local code execution vulnerability has been identified in STIGQter versions 0.1.2 prior to 1.2.7. This vulnerability allows an attacker to execute code with the privileges of the user running STIGQter. Exploitation requires user interaction, as the victim must open a crafted .stigqter file and manually initiate the 'Export HTML' action. The issue arises because STIGQter writes per-STIG HTML files using filenames extracted directly from the SQLite database of the loaded .stigqter project file, without proper validation. This flaw enables the injection of attacker-controlled content into files saved at arbitrary locations, including paths that trigger the execution of the injected code via systemd.
Users can upgrade to STIGQter version 1.2.7, where this vulnerability has been fixed. Instructions for downloading the latest version are available on the STIGQter GitHub page.
