D-Link device DIR878FW1.30B08Hotfix02 was discovered to contain a command injection vulnerability in the twsystem function. This vulnerability allows attackers to execute arbitrary commands via a crafted HNAP1 POST request.

D-Link devices DIR878 DIR878FW1.30B08Hotfix02 and DIR882 DIR882FW1.30B06Hotfix02 were discovered to contain a command injection vulnerability in the system function. This vulnerability allows attackers to execute arbitrary commands via a crafted HNAP1 POST request.

D-Link DIR878 DIR878FW120B05 was discovered to contain a stack overflow in the sub495220 function. This vulnerability allows attackers to cause a Denial of Service (DoS) or execute arbitrary code via a crafted payload.

D-Link DIR878 DIR878FW120B05 was discovered to contain a stack overflow in the sub475FB0 function. This vulnerability allows attackers to cause a Denial of Service (DoS) or execute arbitrary code via a crafted payload.

D-Link DIR878 DIR878FW120B05 was discovered to contain a stack overflow in the sub48AF78 function. This vulnerability allows attackers to cause a Denial of Service (DoS) or execute arbitrary code via a crafted payload.

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 1.20B10BETA. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of HNAP requests. The issue results from incorrect string matching logic when accessing protected pages. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the router. Was ZDI-CAN-10835.

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.

A command injection vulnerability in the protest binary allows an attacker with access to the remote command line interface to execute arbitrary commands as root.
