A vulnerability, which was classified as critical, was found in Netgear D6400 1.0.0.114. This affects an unknown part of the file diag.cgi. The manipulation of the argument host_name leads to os command injection. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early and confirmed the existence of the vulnerability. They reacted very quickly, professional and kind. This vulnerability only affects products that are no longer supported by the maintainer.
AnalysisAI
Remote OS command injection in Netgear D6400 firmware 1.0.0.114 allows authenticated attackers to execute arbitrary commands via the diag.cgi host_name parameter. Public exploit code exists, and the vendor confirmed the vulnerability, but no patch will be issued because the product is end-of-life. EPSS score is low (0.79%) indicating limited likelihood of widespread exploitation despite the exploit's availability.
