Detailsinfo

A vulnerability, which was classified as problematic, was found in Tautulli up to 2.15.x. Affected is the function runGit of the file versioncheck.py. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2025-58763 since 09/04/2025. The exploitability is told to be difficult. It is possible to launch the attack remotely. Additional levels of successful authentication are necessary for exploitation. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1202.

Upgrading to version 2.16.0 eliminates this vulnerability.
