Authentication Bypass vulnerability in D-Link DIR-645 firmware version 1.03 allows remote attackers to gain escalated privileges via function phpcgi_main in cgibin. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

D-Link DIR 645A1 1.06B01_Beta01 was discovered to contain a stack overflow via the service= variable in the genacgi_main function.

D-Link DIR-645 v1.03 was discovered to contain a command injection vulnerability via the QUERY_STRING parameter at __ajax_explorer.sgi.

D-Link DIR-645 1.03 A1 is vulnerable to Buffer Overflow. The hnap_main function in the cgibin handler uses sprintf to format the soapaction header onto the stack and has no limit on the size.

webinc/js/info.php on D-Link DIR-816L 2.06.B09_BETA and DIR-803 1.04.B02 devices allows XSS via the HTTP Referer header. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. NOTE: this is typically not exploitable because of URL encoding (except in Internet Explorer) and because a web page cannot specify that a client should make an additional HTTP request with an arbitrary Referer header

Certain D-Link devices have a hardcoded Alphanetworks user account with TELNET access because of /etc/config/image_sign or /etc/alpha_config/image_sign. This affects DIR-600 B1 V2.01 for WW, DIR-890L A1 v1.03, DIR-615 J1 v100 (for DCN), DIR-645 A1 v1.03, DIR-815 A1 v1.01, DIR-823 A1 v1.01, and DIR-842 C1 v3.00.

An issue was discovered in soap.cgi?service=WANIPConn1 on D-Link DIR-845 before v1.02b03, DIR-600 before v2.17b01, DIR-645 before v1.04b11, DIR-300 rev. B, and DIR-865 devices. There is Command Injection via shell metacharacters in the NewInternalClient, NewExternalPort, or NewInternalPort element of a SOAP POST request.

The D-Link DIR-645 Wired/Wireless Router Rev. Ax with firmware 1.04b12 and earlier allows remote attackers to execute arbitrary commands via a GetDeviceSettings action to the HNAP interface.

Stack-based buffer overflow in the DIR-645 Wired/Wireless Router Rev. Ax with firmware 1.04b12 and earlier allows remote attackers to execute arbitrary code via a long string in a GetDeviceSettings action to the HNAP interface.

Multiple cross-site scripting (XSS) vulnerabilities in D-Link DIR-645 Router (Rev. A1) with firmware before 1.04B11 allow remote attackers to inject arbitrary web script or HTML via the (1) deviceid parameter to parentalcontrols/bind.php, (2) RESULT parameter to info.php, or (3) receiver parameter to bsc_sms_send.php.
