An attacker needs administrator access to exploit it, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-39239 and fix it if it is affected.\n\nWhat it is: CVE-2023-39239 is a high-severity vulnerability in ASUS RT-AC86U, published on 7 Sep 2023. An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-39239 in the wild and no public exploit code.\n\nAffected product: ASUS RT-AC86U. 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-2023-39239/ (Markdown: https://insights.sbomify.com/CVE-2023-39239/index.md)","id":"CVE-2023-39239","markdown":"https://insights.sbomify.com/CVE-2023-39239/index.md","name":"CVE-2023-39239","record":{"aliases":["GHSA-3vqq-6vgg-h45h"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ASUS wireless router","requires_auth":"high_privilege","summary":"A remote attacker with admin privileges can exploit a format string vulnerability in ASUS routers to execute arbitrary code or disrupt services.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"twcert","cpe":[{"product":"rt-ac86u_firmware","vendor":"asus"},{"product":"rt-ax55_firmware","vendor":"asus"},{"product":"rt-ax56u_v2_firmware","vendor":"asus"}],"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-134","name":"Use of Externally-Controlled Format String"}],"description":"It is identified a format string vulnerability in ASUS RT-AX56U V2’s General function API.
