CVE-2016-11022Known exploitationPublic exploitNetwork attack vector

Root code execution via reqMethod shell metacharacters

Published Mar 23, 2020 · Updated Aug 6, 2024

OS command injection in NETGEAR ProSafe WC9500 5.1.0.17, WC7600 5.1.0.17, and WC7520 2.5.0.35 allows remote attackers to execute code. The login_handler.php endpoint passes shell metacharacters from the reqMethod parameter into command execution without neutralization. The public exploit sends an HTTP POST without credentials and receives root command output, enabling complete controller compromise and botnet installation.
