CyberRota Analysis
AI-GeneratedThe Proxmox application view in LibreNMS versions up to and including 26.4.0 is vulnerable to reflected cross-site scripting due to inadequate encoding of user-supplied GET parameters, allowing attackers to execute scripts in the context of an authenticated user's session. This vulnerability can lead to session data theft and other malicious actions if a user is tricked into clicking a crafted link. Organizations using affected versions should prioritize upgrading to version 26.5.0 to mitigate this risk.

Original NVD Description
LibreNMS is a network monitoring system. In versions up to and including 26.4.0, the Proxmox application view is vulnerable to reflected cross-site scripting through the user-supplied instance and vmid GET parameters, which are reflected into the page title without adequate encoding. The parameters are placed into the page title with only strip_tags applied, and the title is then written into an inline document.title assignment through string interpolation, so a single quote terminates the JavaScript string and the remaining input runs as script. An attacker who lures an authenticated user into following a crafted link can execute script in that user's session, enabling actions such as theft of session data. This issue is fixed in version 26.5.0.
