CVE-2022-40719 – D-Link DIR-2150 xupnpd_generic Plugin Command Injection Remote Code Execution Vulnerability

https://notcve.org/view.php?id=CVE-2022-40719

This vulnerability allows network-adjacent attackers to execute arbitrary commands on affected installations of D-Link DIR-2150 4.0.1 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the xupnpd_generic.lua plugin for the xupnpd service, which listens on TCP port 4044 by default. When parsing the feed 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 service account. • https://supportannouncement.us.dlink.com/announcement/publication.aspx?name=SAP10304 https://www.zerodayinitiative.com/advisories/ZDI-22-1223 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
