CVE-2022-26999Public exploitNetwork attack vector

Unauthenticated command injection via static IP parameters

Published Mar 15, 2022 · Updated Aug 3, 2024

Command injection in Arris TR3300 v1.0.13 allows remote attackers to execute arbitrary commands via crafted static IP settings requests. The static IP settings function passes wan_ip_stat, wan_mask_stat, wan_gw_stat, and wan_dns1_stat input into command execution without adequate neutralization. Network reachability to the router interface is sufficient; successful exploitation can compromise confidentiality, integrity, and availability.
