An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-39979 and fix it if it is affected.\n\nWhat it is: CVE-2023-39979 is a critical authentication bypass vulnerability in Moxa MXsecurity Series, published on 2 Sep 2023. 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-2023-39979 in the wild and no public exploit code.\n\nAffected product: Moxa MXsecurity Series. 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-2023-39979/ (Markdown: https://insights.sbomify.com/CVE-2023-39979/index.md)","id":"CVE-2023-39979","markdown":"https://insights.sbomify.com/CVE-2023-39979/index.md","name":"CVE-2023-39979","record":{"aliases":["GHSA-vv74-p9wh-mpf3"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"MXsecurity Series","requires_auth":"none","summary":"Remote attackers can bypass authentication in Moxa MXsecurity devices due to insufficient random values in the web service authenticator.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Moxa","cpe":[{"product":"mxsecurity","vendor":"moxa"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-330","name":"Use of Insufficiently Random Values"},{"id":"CWE-334","name":"Small Space of Random Values"}],"description":"There is a vulnerability in MXsecurity versions prior to 1.0.1 that can be exploited to bypass authentication.
