An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2016-8723 and fix it if it is affected.\n\nWhat it is: CVE-2016-8723 is a high-severity vulnerability in Moxa AWK-3131A Series Industrial IEEE 802.11a/b/g/n wireless AP/bridge/client, published on 13 Apr 2017. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-8723 in the wild and no public exploit code.\n\nAffected product: Moxa AWK-3131A Series Industrial IEEE 802.11a/b/g/n wireless AP/bridge/client. 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-2016-8723/ (Markdown: https://insights.sbomify.com/CVE-2016-8723/index.md)","id":"CVE-2016-8723","markdown":"https://insights.sbomify.com/CVE-2016-8723/index.md","name":"CVE-2016-8723","record":{"aliases":["GHSA-29hm-xg54-5w5x"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial Wireless AP","requires_auth":"none","summary":"An attacker can cause a denial of service in Moxa AWK-3131A wireless access points by sending malformed HTTP GET requests that trigger a null pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"awk-3131a_firmware","vendor":"moxa"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"An exploitable null pointer dereference exists in the Web Application functionality of Moxa AWK-3131A Wireless Access Point running firmware 1.1.
