{"id":"CVE-2026-112360","kind":"vulnerability","aliases":["CVE-2026-112360"],"related":[],"title":"Netis EAP930 firmware: CGI debug endpoint backdoor reachable remotely","description":"A security vulnerability has been detected in Netis EAP930 1.250905.115454. This issue affects the function return200 of the file /cgi-bin/debug of the component CGI Endpoint. The manipulation of the argument SIGNATURE leads to backdoor. The attack may be initiated remotely. A high degree of complexity is needed for the attack. The exploitability is assessed as difficult. The vendor was contacted early about this disclosure but did not respond in any way.","summary":"The Netis EAP930 access point's /cgi-bin/debug endpoint accepts a manipulated SIGNATURE argument that acts as a backdoor.
