An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-43970 in the wild and no public exploit code.\n\nAffected product: Linksys WRT54GL Wireless-G Broadband Router. 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-2022-43970/ (Markdown: https://insights.sbomify.com/CVE-2022-43970/index.md)","id":"CVE-2022-43970","markdown":"https://insights.sbomify.com/CVE-2022-43970/index.md","name":"CVE-2022-43970","record":{"aliases":["GHSA-f4c9-fwv7-5pmf"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Linksys wireless router","requires_auth":"high_privilege","summary":"An authenticated administrator can trigger a stack-based buffer overflow in the router's web server to execute arbitrary commands as root.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"wrt54gl_firmware","vendor":"linksys"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A buffer overflow vulnerability exists in Linksys WRT54GL Wireless-G Broadband Router with firmware \u003c= 4.30.18.006.
