An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-34037 exists.\n\nAffected product: Linksys E1000 v1. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-34037/ (Markdown: https://insights.sbomify.com/CVE-2025-34037/index.md)","id":"CVE-2025-34037","markdown":"https://insights.sbomify.com/CVE-2025-34037/index.md","name":"CVE-2025-34037","record":{"aliases":["GHSA-4c6f-v7q4-2m38"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Linksys router","requires_auth":"none","summary":"Unauthenticated attackers can inject shell commands via CGI endpoints on Linksys routers, enabling arbitrary code execution and potential worm propagation.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"An OS command injection vulnerability exists in various models of E-Series Linksys routers via the /tmUnblock.cgi and /hndUnblock.cgi endpoints over HTTP on port 8080. 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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2014-02-13","github_poc":1,"max_poc_stars":0,"metasploit":1,"nuclei":0,"refs":[{"date":"2014-02-13","kind":"metasploit","ref":"exploit/linux/http/linksys_themoon_exec","stars":null,"title":"Linksys E-Series TheMoon Remote Command Injection"},{"date":"2026-03-26T21:55:13Z","kind":"github_poc","ref":"https://github.com/Taxanehh/CVE-2025-34037","stars":0,"title":"Python port of the Linksys tmUnblock.cgi RCE exploit"}],"tier":"weaponised"},"has_fix":null,"headline":"Linksys Routers E/WAG/WAP/WES/WET/WRT-Series","id":"CVE-2025-34037","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"Weaver E-cology SQL Injection","id":"CVE-2025-34038"},"packages":[],"prev":{"headline":"Shenzhen TVT CCTV-DVR Command Injection","id":"CVE-2025-34036"},"products":["E1000 v1","E1200 v1","E1500 v1","E1550","E2000","E2100L v1","E2500 v1/v2","E3000","E3200","E4200","E900 v1"],"published":"2025-06-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-22","vendors":["Linksys"]},"summary":"Unauthenticated attackers can inject shell commands via CGI endpoints on Linksys routers, enabling arbitrary code execution and potential worm propagation.","url":"https://insights.sbomify.com/CVE-2025-34037/"}
