Description
Stack-based buffer overflow in login_mgr.cgi in D-Link firmware DNR-320L and DNS-320LW before 1.04b08, DNR-322L before 2.10 build 03, DNR-326 before 2.10 build 03, and DNS-327L before 1.04b01 allows remote attackers to execute arbitrary code by crafting malformed "Host" and "Referer" header values.
Exploitation
Not listed in the CISA Known Exploited Vulnerabilities catalogue as of 2026.09.04. That is an absence of confirmed public exploitation, not evidence that exploitation has not occurred. EPSS models a 20.9% probability of exploitation activity in the next 30 days, placing it in the top decile of all scored CVEs.
