  1. CVE-2026-112016 6.5 Moyenne

    Netcore NR256CN

    Netcore NR256CN through 1.5.140116 contains an unauthenticated file write vulnerability in the Boa-derived /bin/boa web server that allows remote attackers to overwrite update and restore staging files. Attackers can POST to a non-existent .cgi pathname to write attacker-controlled content into /tmp/boa_temp.update or /tmp/boa_temp.para, tampering with pending firmware updates or configuration restores or causing denial of service.

  2. CVE-2026-111712 6.5 Moyenne

    Netcore NR256CN

    Netcore NR256CN through 1.5.140116 contains an authentication bypass vulnerability that allows unauthenticated attackers to reach protected management CGI handlers by prefixing the URI with a public route. Attackers can request paths prefixed with l7_web_auth.cgi or an .ico route to invoke protected management handlers without credentials.

  3. CVE-2026-111711 9.8 Critique

    Netcore NR256CN

    Netcore NR256CN through 1.5.140116 contains a pre-authentication stack overflow vulnerability in the Boa web server's user_ok() function, which copies Basic-auth usernames with unbounded strcpy() calls into 64-byte stack buffers. Unauthenticated attackers can send a username longer than 63 bytes to any protected /router/*.cgi route to crash the main Boa process or potentially execute code.

  4. CVE-2026-111710 7.5 Élevée

    Netcore NR256CN

    Netcore NR256CN through 1.5.140116 contains a NULL pointer dereference vulnerability in the Boa web server's user_auth() function that allows unauthenticated attackers to crash the server via a malformed Authorization header. Attackers can send a Basic Authorization value lacking a colon, such as one decoding to a single character, to protected routes like /router/get_user_type.cgi to kill the main Boa process and deny management interface access.
