Certain D-Link devices have a hardcoded Alphanetworks user account with TELNET access because of /etc/config/imagesign or /etc/alphaconfig/imagesign. 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.

D-Link DIR-815 REV. B (with firmware through DIR-815REVBFIRMWAREPATCH2.07.B01) devices have permission bypass and information disclosure in /htdocs/web/getcfg.php, as demonstrated by a /getcfg.php?a=%0aPOSTSERVICES%3DDEVICE.ACCOUNT%0aAUTHORIZEDGROUP%3D1 request.

D-Link DIR-815 REV. B (with firmware through DIR-815REVBFIRMWAREPATCH2.07.B01) devices have XSS in the RESULT parameter to /htdocs/webinc/js/info.php.

D-Link DIR-815 REV. B (with firmware through DIR-815REVBFIRMWAREPATCH2.07.B01) devices have XSS in the Treturn parameter to /htdocs/webinc/js/bscsmsinbox.php.

Cross-site request forgery (CSRF) vulnerability in D-Link DIR-815 devices with firmware before 2.07.B01 allows remote attackers to hijack the authentication of arbitrary users for requests that insert XSS sequences.

The remote administration UI in D-Link DIR-815 devices with firmware before 2.07.B01 allows remote attackers to bypass intended access restrictions via unspecified vectors.

D-Link DIR-815 devices with firmware before 2.07.B01 allow remote attackers to obtain sensitive information by leveraging cleartext storage of the administrative password.

D-Link DIR-815 devices with firmware before 2.07.B01 allow remote attackers to obtain sensitive information by leveraging cleartext storage of the wireless key.

The remote administration interface in D-Link DIR-815 devices with firmware before 2.03.B02 allows remote attackers to execute arbitrary commands via vectors related to an "HTTP command injection issue."
