CVE-2025-58762
No affected components available
Tautulli is a Python based monitoring and tracking tool for Plex Media Server. In Tautulli v2.15.3 and earlier, an attacker with administrative access can use the pms_image_proxy endpoint to write arbitrary python scripts into the application filesystem. This leads to remote code execution when combined with the Script notification agent. If an attacker with administrative access changes the URL of the PMS to a server they control, they can then abuse the pms_image_proxy to obtain a file write into the application filesystem. This can be done by making a pms_image_proxy request with a URL in the img parameter and the desired file name in the img_format parameter. Tautulli then uses a hash of the desired metadata together with the img_format in order to construct a file path. Since the attacker controls img_format which occupies the end of the file path, and img_format is not sanitised, the attacker can then use path traversal characters to specify filename of their choosing. If the specified file does not exist, Tautaulli will then attempt to fetch the image from the configured PMS. Since the attacker controls the PMS, they can return arbitrary content in response to this request, which will then be written into the specified file. An attacker can write an arbitrary python script into a location on the application file system. The attacker can then make use of the built-in Script notification agent to run the local script, obtaining remote code execution on the application server. Users should upgrade to version 2.16.0 to receive a patch.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs high-level or administrative privileges. No user interaction is needed for the attacker to exploit this vulnerability. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
