# CVE-2025-4632: Samsung MagicINFO 9 Server Path Traversal 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 Samsung MagicINFO 9 Server. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-05-22, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-06-12 ; treat that as the outer limit, not the target.
- EPSS 24.1% , percentile 98: FIRST’s model estimates a 24.1% chance of exploitation activity in the next 30 days, higher than 98% 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.
