CyberRota Analysis
AI-GeneratedThe Netis NC63 router firmware version 3.0.0.3327 is vulnerable to an unauthenticated firmware update flaw, allowing attackers to upload unsigned firmware images without valid session credentials. This vulnerability could lead to persistent compromise of the router, as the firmware update process lacks proper authentication and relies on weak validation methods. Organizations using this router model should prioritize patching this vulnerability to mitigate the risk of unauthorized access and potential exploitation.

Original NVD Description
Netis NC63 router firmware V3.0.0.3327 contains an unauthenticated firmware update vulnerability that allows unauthenticated attackers to submit unsigned firmware images by exploiting a missing authentication enforcement flaw in the Boa web server and netis.cgi CGI dispatcher. Attackers can send a multipart POST request to /cgi-bin/upload_fw.cgi without a valid session cookie, bypassing authentication because Boa grants access to any path containing '.cgi' regardless of cookie validation, and netis.cgi reads but does not enforce the authentication state before invoking the firmware update handler, which accepts images validated only by a forgeable additive checksum and static product strings rather than a cryptographic signature, potentially enabling persistent router compromise.
