# CVE-2020-25078: D-Link DCS-2530L and DCS-2670L Devices Unspecified 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 D-Link DCS-2530L and DCS-2670L Devices. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-08-05, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-08-26 ; treat that as the outer limit, not the target.
- EPSS 97.5% , percentile 99.9: FIRST’s model estimates a 97.5% chance of exploitation activity in the next 30 days, higher than 99.9% 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.
