CVE-2024-39915 – Authenticated remote code execution in Thruk

https://notcve.org/view.php?id=CVE-2024-39915

Thruk is a multibackend monitoring webinterface for Naemon, Nagios, Icinga and Shinken using the Livestatus API. This authenticated RCE in Thruk allows authorized users with network access to inject arbitrary commands via the URL parameter during PDF report generation. The Thruk web application does not properly process the url parameter when generating a PDF report. An authorized attacker with access to the reporting functionality could inject arbitrary commands that would be executed when the script /script/html2pdf.sh is called. The vulnerability can be exploited by an authorized user with network access. • https://github.com/sni/Thruk/commit/7e7eb251e76718a07639c4781f0d959d817f173b https://github.com/sni/Thruk/security/advisories/GHSA-r7gx-h738-4w6f • CWE-94: Improper Control of Generation of Code ('Code Injection') •
