It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2023-32634 and fix it if it is affected.\n\nWhat it is: CVE-2023-32634 is a high-severity authentication bypass vulnerability in SoftEther VPN, published on 12 Oct 2023. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-32634 exists.\n\nAffected product: SoftEther VPN. 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-2023-32634/ (Markdown: https://insights.sbomify.com/CVE-2023-32634/index.md)","id":"CVE-2023-32634","markdown":"https://insights.sbomify.com/CVE-2023-32634/index.md","name":"CVE-2023-32634","record":{"aliases":["GHSA-q5mg-3r24-hvx2"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"VPN server software","requires_auth":"none","summary":"An attacker can bypass authentication in SoftEther VPN via a local man-in-the-middle attack, potentially gaining unauthorized access.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"vpn","vendor":"softether"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-300","name":"Channel Accessible by Non-Endpoint"}],"description":"An authentication bypass vulnerability exists in the CiRpcServerThread() functionality of SoftEther VPN 5.01.9674 and 4.41-9782-beta.
