CISA KEV · added 2025-02-06 CVSS 7.8 High EPSS 8.3% · p95
Should you act?
Exploited: patch now if you run it
CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Yes, if you run Audinate Dante Discovery. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-02-06, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-02-27; treat that as the outer limit, not the target.
- EPSS 8.3%, percentile 95: FIRST’s model estimates a 8.3% chance of exploitation activity in the next 30 days, higher than 95% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.
What it is
mDNSResponder.exe is vulnerable to DLL Sideloading attack. Executable improperly specifies how to load the DLL, from which folder and under what conditions. In these scenarios, a malicious attacker could be using the valid and legitimate executable to load malicious files.
CISA’s summary
Dante Discovery contains a process control vulnerability in mDNSResponder.exe that all allows for a DLL sideloading attack. A local attacker can leverage this vulnerability in the Dante Application Library to execute arbitrary code.
Weakness type: CWE-114.
