An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-28703 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-2023-28703/ (Markdown: https://insights.sbomify.com/CVE-2023-28703/index.md)","id":"CVE-2023-28703","markdown":"https://insights.sbomify.com/CVE-2023-28703/index.md","name":"CVE-2023-28703","record":{"aliases":["GHSA-2pwg-h86c-qrp2"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ASUS router","requires_auth":"high_privilege","summary":"A remote attacker with admin privileges can execute arbitrary commands or cause denial of service via a stack-based buffer overflow in the router's CGI function.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"twcert","cpe":[{"product":"rt-ac86u_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-121","name":"Stack-based Buffer Overflow"}],"description":"ASUS RT-AC86U’s specific cgi function has a stack-based buffer overflow vulnerability due to insufficient validation for network packet header length.
