DescriptionGitHub Advisory

Tautulli is a Python based monitoring and tracking tool for Plex Media Server. A command injection vulnerability in Tautulli v2.15.3 and prior allows attackers with administrative privileges to obtain remote code execution on the application server. This vulnerability requires the application to have been cloned from GitHub and installed manually. When Tautulli is cloned directly from GitHub and installed manually, the application manages updates and versioning through calls to the git command. In the code, this is performed through the runGit function in versioncheck.py. Since shell=True is passed to subproces.Popen, this call is vulnerable to subject to command injection, as shell characters within arguments will be passed to the underlying shell. A concrete location where this can be triggered is in the checkout_git_branch endpoint. This endpoint stores a user-supplied remote and branch name into the GIT_REMOTE and GIT_BRANCH configuration keys without sanitization. Downstream, these keys are then fetched and passed directly into runGit using a format string. Hence, code execution can be obtained by using $() interpolation in a command. Version 2.16.0 contains a fix for the issue.

Version 2.16.0 contains a fix for the issue. Affected products include: Tautulli. Version information: Version 2.16.0.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Avoid passing user input to shell commands. Use language-specific APIs instead of shell execution. Apply strict input validation with allowlists.
