Loading vulnerability…
A command injection vulnerability exists in D-Link DIR-859 firmware versions 1.05 and 1.06B01 Beta01. The vulnerability is present in the ssdpcgi() function located in /htdocs/cgibin, which handles M-SEARCH requests. The HTTP_ST header is improperly validated using strstr, allowing an attacker to inject arbitrary OS commands via the urn: parameter by concatenating shell metacharacters.

This repository contains a single Metasploit module (modules/exploits/linux/upnp/dlink_dir859_exec_ssdpcgi.rb) that exploits an unauthenticated remote command execution vulnerability (CVE-2019-20215) in the ssdpcgi component of certain D-Link devices, such as the DIR-859 router. The exploit works by sending a specially crafted UDP M-SEARCH request to the SSDP service (UDP port 1900, multicast address 239.255.255.250), injecting commands via the 'ST' header. The module uses Metasploit's command stager to deliver a payload (default: linux/mipsbe/meterpreter_reverse_tcp) using either wget or echo. The exploit is fully weaponized, allowing for customizable payloads and reliable exploitation. The module is marked as deprecated in favor of a newer module but remains functional. The only file in the repository is the Metasploit exploit module, written in Ruby.
This repository contains a single Metasploit module (Ruby file) that exploits a command injection vulnerability in the UPnP implementation of multiple D-Link router models. The exploit works by sending a specially crafted UDP M-SEARCH packet to the target device's UPnP service (typically on UDP port 1900), injecting a shell command into the ST (Search Target) field. If the target is vulnerable, the command is executed as root, granting full remote code execution. The module supports both direct command execution and staged payloads (such as Meterpreter), and includes logic to fingerprint the device and check firmware versions via HTTP. The exploit targets a wide range of D-Link routers and firmware versions, as listed in the module's description, and is associated with several CVEs (CVE-2023-33625, CVE-2020-15893, CVE-2019-20215). The code is weaponized, as it is part of the Metasploit framework and supports customizable payloads. The main attack vector is network-based, requiring access to the target's UDP port 1900.
