TRENDnet TEW-827DRU devices through 2.06B04 contain multiple command injections in apply.cgi via the action pppoe_connect, ru_pppoe_connect, or dhcp_connect with the key wan_ifname (or wan0_dns), allowing an authenticated user to run arbitrary commands on the device.

TRENDnet TEW-827DRU devices through 2.06B04 contain a stack-based buffer overflow in the ssi binary. The overflow allows an unauthenticated user to execute arbitrary code by POSTing to apply_sec.cgi via the action ping_test with a sufficiently long ping_ipaddr key.

TRENDnet TEW-827DRU devices through 2.06B04 contain multiple command injections in apply.cgi via the action send_log_email with the key auth_acname (or auth_passwd), allowing an authenticated user to run arbitrary commands on the device.

TRENDnet ProView Wireless camera TV-IP512WN 1.0R 1.0.4 is vulnerable to an unauthenticated stack-based buffer overflow in handling RTSP packets. This may result in remote code execution or denial of service. The issue is in the binary rtspd (in /sbin) when parsing a long "Authorization: Basic" RTSP header.

An issue was discovered on D-Link DIR-825 Rev.B 2.10 devices. They allow remote attackers to execute arbitrary commands via the wps_sta_enrollee_pin parameter in a set_sta_enrollee_pin.cgi POST request. TRENDnet TEW-632BRP 1.010B32 is also affected.

An issue was discovered on D-Link DIR-825 Rev.B 2.10 devices. They allow remote attackers to execute arbitrary commands via the date parameter in a system_time.cgi POST request. TRENDnet TEW-632BRP 1.010B32 is also affected.

An issue was discovered on D-Link DIR-825 Rev.B 2.10 devices. They allow remote attackers to execute arbitrary commands via the dns_query_name parameter in a dns_query.cgi POST request. TRENDnet TEW-632BRP 1.010B32 is also affected.
