apply.cgi on the TRENDnet TEW-632BRP 1.010B32 router has a buffer overflow via long strings to the SOAPACTION:HNAP1 interface.

system.cgi on TRENDnet TV-IP110WN cameras has a buffer overflow caused by an inadequate source-length check before a strcpy operation in the respondAsp function. Attackers can exploit the vulnerability by using the languse parameter with a long string. This affects 1.2.2 build 28, 64, 65, and 68.

An issue was discovered on TRENDnet TEW-651BR 2.04B1, TEW-652BRP 3.04b01, and TEW-652BRU 1.00b12 devices. A buffer overflow occurs through the get_set.ccp ccp_act parameter.

An issue was discovered on TRENDnet TEW-651BR 2.04B1, TEW-652BRP 3.04b01, and TEW-652BRU 1.00b12 devices. OS command injection occurs through the get_set.ccp lanHostCfg_HostName_1.1.1.0.0 parameter.

TRENDnet TEW-751DR v1.03B03, TEW-752DRU v1.03B01, and TEW733GR v1.03B01 devices allow authentication bypass via an AUTHORIZED_GROUP=1 value, as demonstrated by a request for getcfg.php.

Buffer overflow in apply.cgi on TRENDnet TEW-632BRP 1.010B32 and TEW-673GRU devices allows attackers to hijack the control flow to any attacker-specified location by crafting a POST request payload (with authentication).

Buffer overflow in video.cgi on TRENDnet TV-IP110WN V1.2.2 build 68, V1.2.2.65, and V1.2.2 build 64 and TV-IP121WN V1.2.2 build 28 devices allows attackers to hijack the control flow to any attacker-specified location by crafting a POST request payload (without authentication).

Buffer overflow in network.cgi on TRENDnet TV-IP110WN V1.2.2 build 68, V1.2.2.65, and V1.2.2 build 64 and TV-IP121WN V1.2.2 build 28 devices allows attackers to hijack the control flow to any attacker-specified location by crafting a POST request payload (without authentication).

TRENDnet TEW-673GRU v1.00b40 devices have an OS command injection vulnerability in the start_arpping function of the timer binary, which allows remote attackers to execute arbitrary commands via three parameters (dhcpd_start, dhcpd_end, and lan_ipaddr) passed to the apply.cgi binary through a POST request.

TRENDnet TEW-823DRU devices with firmware before 1.00b36 have a hardcoded password of kcodeskcodes for the root account, which makes it easier for remote attackers to obtain access via an FTP session.

TRENDnet TS-S402 has a backdoor to enable TELNET.

Undocumented TELNET service in TRENDnet TEW-691GR and TEW-692GR when a web page named backdoor contains an HTML parameter of password and a value of j78G¬DFdg_24Mhw3.
