A Command Injection vulnerability exists in the /var/www/cgi-bin/rtpd.cgi script in D-Link IP Cameras DCS-3411/3430 firmware 1.02, DCS-5605/5635 1.01, DCS-1100L/1130L 1.04, DCS-1100/1130 1.03, DCS-1100/1130 1.04US, DCS-2102/2121 1.05RU, DCS-3410 1.02, DCS-5230 1.02, DCS-5230L 1.02, DCS-6410 1.00, DCS-7410 1.00, DCS-7510 1.00, and WCS-1100 1.02, which could let a remote malicious user execute arbitrary commands through the camera’s web interface.
/etc/rc.d/rc.local on the D-Link DCS-2121 camera with firmware 1.04 configures a hardcoded password of admin for the root account, which makes it easier for remote attackers to obtain shell access by leveraging a running telnetd server.
recordertest.cgi on the D-Link DCS-2121 camera with firmware 1.04 allows remote attackers to execute arbitrary commands via shell metacharacters in the Password field, related to a "semicolon injection" vulnerability.
