An issue in D-Link DIR-1253 MESH V1.6.1684 allows an attacker to escalate privileges via the etc/shadow.sample component

An issue was discovered on D-Link DVA-5592 A1_WI_20180823 devices. If the PIN of the page "/ui/cbpc/login" is the default Parental Control PIN (0000), it is possible to bypass the login form by editing the path of the cookie "sid" generated by the page. The attacker will have access to the router control panel with administrator privileges.

D-Link DIR-605L Hardware Revision B2 (End-of-Life, EOL) contains a hardcoded telnet backdoor. The device starts a telnet daemon at boot via /bin/telnetd.sh with the username "Alphanetworks" and the static password "wrgn76_dlwbr_dir605L" read from /etc/alpha_config/image_sign. The custom telnetd binary accepts a -u user:password flag, and the custom login binary uses strcmp() to validate credentials. Successful authentication grants an unauthenticated attacker on the local network a root shell with full administrative control. The device has reached End-of-Life (EOL) and will not receive patches.

The custom telnetd binary accepts a -u user:password flag, and the custom login binary uses strcmp() to validate credentials. Successful authentication grants an unauthenticated attacker on the local network a root shell with full administrative control.  The device has reached End-of-Life (EOL) and will not receive patches.

D-Link DIR-600L Hardware Revision A1 (End-of-Life) contains a hardcoded telnet backdoor.

Buffer overflow vulnerability in DLINK 619L version B 2.06beta via the FILECODE parameter on login.

An issue was discovered in apply.cgi on D-Link DAP-1520 devices before 1.10b04Beta02. Whenever a user performs a login action from the web interface, the request values are being forwarded to the ssi binary. On the login page, the web interface restricts the password input field to a fixed length of 15 characters. The problem is that validation is being done on the client side, hence it can be bypassed. When an attacker manages to intercept the login request (POST based) and tampers with the vulnerable parameter (log_pass), to a larger length, the request will be forwarded to the webserver. This results in a stack-based buffer overflow. A few other POST variables, (transferred as part of the login request) are also vulnerable: html_response_page and log_user.
