Details

PLANET GS-4210-16P2S firmware before 3.441b260626 contains an authenticated OS command injection vulnerability in /cgi-bin/httpuploadcert.cgi. The certificate password field in a certificate upload request is incorporated into a shell command without sanitization of shell metacharacters. A remote attacker with administrator web credentials can submit a crafted certificate upload request to execute arbitrary operating-system commands on the device.
