In Tautulli 2.1.9, CSRF in the /shutdown URI allows an attacker to shut down the remote media server.
Noroxi assessment
Priority: This week (action score 60/100)
- A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
- A ready-made attack tool exists and the flaw can be exploited over the network without an account, so priority is at least “This week”.
- Probability of exploitation in the next 30 days: 14.7% (FIRST EPSS); higher than 96.6% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
- No fixed version is recorded, but the references include a patch (commit or PR) link.
Don’t wait for the next maintenance window. See the fix and affected versions sections below.
