dir-878_firmware

An issue was discovered in prog.cgi on D-Link DIR-878 1.30B08 devices. Because strcat is misused, there is a stack-based buffer overflow that does not require authentication.

D-Link DIR-878 1.02B05 is vulnerable to Incorrect Access Control.

D-Link DIR878 1.02B04 and 1.02B05 are vulnerable to Buffer Overflow.

D-Link DIR878 1.30B08 Hotfix_04 was discovered to contain a command injection vulnerability via the component /bin/proc.cgi.

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.

D-Link DIR-878 has inadequate filtering for special characters in the webpage input field. An unauthenticated LAN attacker can perform command injection attack to execute arbitrary system commands to control the system or disrupt service.
