An attacker needs administrator access to exploit it, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-43973 and fix it if it is affected.\n\nWhat it is: CVE-2022-43973 is a high-severity command injection vulnerability in Linksys WRT54GL Wireless-G Broadband Router, published on 9 Jan 2023. An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-43973 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-2022-43973/ (Markdown: https://insights.sbomify.com/CVE-2022-43973/index.md)","id":"CVE-2022-43973","markdown":"https://insights.sbomify.com/CVE-2022-43973/index.md","name":"CVE-2022-43973","record":{"aliases":["GHSA-j637-xgw5-6q5c"],"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 execute arbitrary root commands on Linksys WRT54GL routers via a malicious POST request due to unvalidated input in the Check_TSSI function.","user_interaction":"not_required","vuln_class":"command_injection"},"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-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"An arbitrary code execution vulnerability exisits in Linksys WRT54GL Wireless-G Broadband Router with firmware \u003c= 4.30.18.006.
