CyberRota Analysis
AI-GeneratedThe Netis NC63 firmware is vulnerable to a stack-based buffer overflow that allows unauthenticated remote attackers to execute arbitrary code with root privileges by submitting an oversized Base64-encoded password to the login handler. This critical vulnerability arises from insufficient output length validation in the custom Base64 decoder, posing a significant risk to devices running this firmware. Organizations using affected Netis products should prioritize immediate patching or mitigation efforts to protect against potential exploitation.

Original NVD Description
Netis NC63 firmware through V3.0.0.3327 contains a stack-based buffer overflow vulnerability that allows unauthenticated remote attackers to overwrite saved stack state by submitting an oversized Base64-encoded password to the login handler in /bin/netis.cgi. Attackers can exploit the custom Base64 decoder's lack of output length validation against the fixed-size stack buffer to achieve remote code execution with root privileges, as the Boa web server executes the CGI environment as root.
