EPSS Score33.7%

EPSS (Exploit Prediction Scoring System) estimates a 33.7% chance this CVE is exploited in the wild within the next 30 days — higher than 98% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.

D-Link DNR-322L contains a download of code without integrity check vulnerability that could allow an authenticated attacker to execute OS level commands on the device. The impacted products could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization.
