Plex: >> Media Server >> 1.13.2.5154 Security Vulnerabilities
An issue was discovered in Plex Media Server through 1.24.4.5081-e362dc1ee. An attacker (with a foothold in a endpoint via a low-privileged user account) can access the exposed RPC service of the update service component. This RPC functionality allows the attacker to interact with the RPC functionality and execute code from a path of his choice (local, or remote via SMB) because of a TOCTOU race condition. This code execution is in the context of the Plex update service (which runs as SYSTEM).

The Camera Upload functionality in Plex Media Server through 1.18.2.2029 allows remote authenticated users to write files anywhere the user account running the Plex Media Server has permissions. This allows remote code execution via a variety of methods, such as (on a default Ubuntu installation) creating a .ssh folder in the plex user's home directory via directory traversal, uploading an SSH authorized_keys file there, and logging into the host as the Plex user via SSH.

In Plex Media Server 1.13.2.5154, the XML parsing engine for SSDP/UPnP functionality is vulnerable to an XML External Entity Processing (XXE) attack. Remote, unauthenticated attackers can use this vulnerability to: (1) Access arbitrary files from the filesystem with the same permission as the user account running Plex, (2) Initiate SMB connections to capture a NetNTLM challenge/response and crack to cleartext password, or (3) Initiate SMB connections to relay a NetNTLM challenge/response and achieve Remote Command Execution in Windows domains.
