The CGI scripts improperly process user-supplied input passed to the ttcp_ip parameter without sanitization, allowing unauthenticated attackers to inject shell commands. This vulnerability was reported to be exploited in the wild by the \"TheMoon\" worm  in 2014 to deploy a MIPS ELF payload, enabling arbitrary code execution on the router. Additionally, this vulnerability may affect other Linksys products to include, but not limited to, WAG/WAP/WES/WET/WRT-series router models and Wireless-N access points and routers. Exploitation evidence was observed by the Shadowserver Foundation on 2025-02-06 UTC.","published":"2025-06-24T01:15:25.037","modified":"2026-07-22T16:17:05.520","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://isc.sans.edu/diary/17633"},{"type":"WEB","url":"https://vulncheck.com/advisories/linksys-routers-command-injection"},{"type":"WEB","url":"https://www.exploit-db.com/exploits/31683"},{"type":"WEB","url":"https://github.com/Jarrettgohxz/CVE-research/tree/main/Linksys/E-series/CVE-2025-34037"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-07-22T16:17:05.520"}}
