| Título | Netcore NR268 Router NR268-V1.7.121109.bin Improper Authentication |
|---|
| Descrição | Boa reads credentials from /tmp/passwd, and user_ok() returns success when that lookup fails. process_header_end() treats any positive user_auth() result as authorized and continues into CGI execution. While /tmp/passwd is missing or malformed, any HTTP Basic header is accepted on the /router/*.cgi surface, including privileged write actions. Representative probes against /router/WebPortSet_show.cgi and /router/WebRemotePortShow.cgi with wrong credentials reach the CGI path instead of returning 401. |
