CVE-2023-50089Public exploitNetwork attack vector

Authenticated command execution via unsanitized User-Agent

Published Dec 15, 2023 · Updated Nov 26, 2024

Command injection in NETGEAR WNR2000v4 1.0.0.70 allows remote authenticated users to execute commands through SOAP authentication. The soap_auth function inserts the HTTP User-Agent into an echo command with sprintf and passes it to system without neutralization. Successful SOAP authentication is required, after which injected shell syntax runs with the router service privileges.
