CyberRota Analysis
AI-GeneratedVersions of UpSnap prior to 5.4.0 are vulnerable to an OS command injection flaw that allows low-privileged users to execute arbitrary commands on the server through unsafe interpolation of user-controlled values in device management commands. This critical vulnerability, affecting both Windows and Linux platforms, can lead to authenticated Remote Code Execution (RCE). Organizations using UpSnap should prioritize upgrading to version 5.4.0 to mitigate this significant security risk.

Original NVD Description
UpSnap is a wake on lan web app. Versions prior to 5.4.0 have an OS command injection vulnerability in the UpSnap’s device management functionality due to the presence of unsafe shell command template interpolation using the ip and the mac fields. User-controlled values can be inserted into the wake_cmd and shutdown_cmd templates and executed via /bin/sh -c (Linux) or cmd /C (Windows) without sanitization, resulting in an authenticated Remote Code Execution (RCE). A low-privileged user with permission to create or edit devices can execute arbitrary operating system commands on the UpSnap hosted server. Version 5.4.0 patches the issue.
