Summary
This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DIR-867, DIR-878, and DIR-882 routers with firmware 1.10B04. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of HNAP login requests. The issue results from the lack of proper implementation of the authentication algorithm. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the router. Was ZDI-CAN-9470.

Summary
This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of D-Link DIR-867, DIR-878, and DIR-882 routers with firmware 1.10B04. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of HNAP login requests. The issue results from the lack of proper handling of empty passwords. An attacker can leverage this vulnerability to execute arbitrary code on the router. Was ZDI-CAN-9471.

Summary
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of multiple D-Link routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the lighttpd service, which listens on TCP port 80 by default. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-13796.

Summary
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DVA-2800 and DSL-2888A routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the dhttpd service, which listens on TCP port 8008 by default. When parsing the path parameter, the process does not properly validate a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the web server. Was ZDI-CAN-10911.

Summary
This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of D-Link DVA-2800 and DSL-2888A routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the dhttpd service, which listens on TCP port 8008 by default. The issue results from incorrect string matching logic when accessing protected pages. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-10912.
