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-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.

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.

The ping tool in multiple D-Link and TRENDnet devices allow remote attackers to execute arbitrary code via the ping_addr parameter to ping.ccp.

TRENDnet WiFi Baby Cam TV-IP743SIC has a password of admin for the backdoor root account.

Buffer overflow in Broadcom ACSD allows remote attackers to execute arbitrary code via a long string to TCP port 5916. This component is used on routers of multiple vendors including ASUS RT-AC66U and TRENDnet TEW-812DRU.

Stack-based buffer overflow in UltraCamLib in the UltraCam ActiveX Control (UltraCamX.ocx) for the TRENDnet SecurView camera TV-IP422WN allows remote attackers to execute arbitrary code via a long string to the (1) CGI_ParamSet, (2) OpenFileDlg, (3) SnapFileName, (4) Password, (5) SetCGIAPNAME, (6) AccountCode, or (7) RemoteHost function.

TRENDnet TEW-812DRU router allows remote authenticated users to execute arbitrary commands via shell metacharacters in the (1) wan network prefix to internet/ipv6.asp; (2) remote port to adm/management.asp; (3) pptp username, (4) pptp password, (5) ip, (6) gateway, (7) l2tp username, or (8) l2tp password to internet/wan.asp; (9) NtpDstStart, (10) NtpDstEnd, or (11) NtpDstOffset to adm/time.asp; or (12) device url to adm/management.asp. NOTE: vectors 9, 10, and 11 can be exploited by unauthenticated remote attackers by leveraging CVE-2013-3098.

Multiple cross-site request forgery (CSRF) vulnerabilities in TRENDnet TEW-812DRU router with firmware before 1.0.9.0 allow remote attackers to hijack the authentication of administrators for requests that (1) change admin credentials in a request to setSysAdm.cgi, (2) enable remote management or (3) enable port forwarding in an Apply action to uapply.cgi, or (4) have unspecified impact via a request to setNTP.cgi. NOTE: some of these details are obtained from third party information.

Stack-based buffer overflow in the UltraMJCam ActiveX Control in TRENDnet SecurView TV-IP121WN Wireless Internet Camera allows remote attackers to execute arbitrary code via a long string to the OpenFileDlg method.
