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.

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 DIR878 1.30B08 was discovered to contain a stack overflow in the sub_48d630 function. This vulnerability allows attackers to cause a Denial of Service (DoS) or execute arbitrary code via a crafted payload.

D-Link DIR-878 - Command Injection

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.

D-Link device DIR_878_FW1.30B08_Hotfix_02 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 DIR_878 DIR_878_FW1.30B08_Hotfix_02 and DIR_882 DIR_882_FW1.30B06_Hotfix_02 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.

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.

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.

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.

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 1.20B10_BETA. 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.

An issue was discovered on D-Link DIR-878 1.12B01 devices. Because strncpy is misused, there is a stack-based buffer overflow vulnerability that does not require authentication via the HNAP_AUTH HTTP header.

An issue was discovered on D-Link DIR-878 1.12B01 devices. At the /HNAP1 URI, an attacker can log in with a blank password.

An issue was discovered on D-Link DIR-878 devices with firmware 1.12A1. This issue is a Command Injection allowing a remote attacker to execute arbitrary code, and get a root shell. A command Injection vulnerability allows attackers to execute arbitrary OS commands via a crafted /HNAP1 POST request. This occurs when any HNAP API function triggers a call to the system function with untrusted input from the request body for the SetStaticRouteIPv4Settings API function, as demonstrated by shell metacharacters in the Gateway field.
