# CVE-2024-12356: BeyondTrust Privileged Remote Access (PRA) and Remote Support (RS) Command Injection Vulnerability 

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run BeyondTrust Privileged Remote Access (PRA) and Remote Support (RS). CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-12-19, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-12-27 ; treat that as the outer limit, not the target.
- EPSS 87.3% , percentile 99.8: FIRST’s model estimates a 87.3% chance of exploitation activity in the next 30 days, higher than 99.8% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
