| Title | netcore NBR200V2 V1.3.241127.071246 Command Injection |
|---|
| Description | Netcore NBR200V2 firmware V1.3.241127.071246 contains a remote command injection vulnerability in the firmware upgrade CGI endpoint. The script URL-decodes attacker-controlled query-string data and then evaluates derived parameter names with eval. Although the helper strips several shell metacharacters, newline characters survive decoding and remain syntactically meaningful to the shell. A remote attacker can therefore inject arbitrary shell commands before the session or upgrade validation logic completes. The impact includes remote reboot, denial of service, and arbitrary code execution. |
