It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-35317 and fix it if it is affected.\n\nWhat it is: CVE-2023-35317 is a high-severity unsafe deserialization vulnerability in Microsoft Windows Server 2012, published on 11 Jul 2023. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-35317 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows Server 2012. 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-2023-35317/ (Markdown: https://insights.sbomify.com/CVE-2023-35317/index.md)","id":"CVE-2023-35317","markdown":"https://insights.sbomify.com/CVE-2023-35317/index.md","name":"CVE-2023-35317","record":{"aliases":["GHSA-pcx7-hvg4-wg56"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows Server Update Service","requires_auth":"low_privilege","summary":"An attacker can exploit a deserialization flaw in WSUS to escalate privileges on affected Windows Server systems.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_server_2012","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"},{"product":"windows_server_2022","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Windows Server Update Service (WSUS) Elevation of Privilege Vulnerability","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-11-16","github_poc":1,"max_poc_stars":15,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-11-16T08:10:33Z","kind":"github_poc","ref":"https://github.com/M507/CVE-2025-59287-PoC","stars":15,"title":"Unauthenticated RCE PoC in Microsoft Windows Server Update Service (WSUS) - CVE-2025-59287 \u0026 CVE-2023-35317"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Windows Server Update Service (WSUS) Elevation of Privilege Vulnerability","id":"CVE-2023-35317","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:windows_server_2012","products":["microsoft:windows_server_2012","microsoft:windows_server_2016","microsoft:windows_server_2019","microsoft:windows_server_2022"],"type":"deserialization","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Remote Procedure Call Runtime Denial of Service Vulnerability","id":"CVE-2023-35318"},"packages":[],"prev":{"headline":"Remote Procedure Call Runtime Information Disclosure Vulnerability","id":"CVE-2023-35316"},"products":["Windows Server 2012","Windows Server 2012 (Server Core installation)","Windows Server 2012 R2","Windows Server 2012 R2 (Server Core installation)","Windows Server 2016","Windows Server 2016 (Server Core installation)","Windows Server 2019","Windows Server 2019 (Server Core installation)","Windows Server 2022"],"published":"2023-07-11","related":[{"cvss_score":9.8,"headline":"Microsoft Windows Server Update Service (WSUS) Deserialization of Untrusted Data","id":"CVE-2025-59287","kev_date_added":"2025-10-24","published":"2025-10-14"},{"cvss_score":9.8,"headline":"Windows Services for NFS ONCRPC XDR Driver Remote Code Execution Vulnerability","id":"CVE-2026-69595","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":9.8,"headline":"Windows Services for NFS ONCRPC XDR Driver Remote Code Execution Vulnerability","id":"CVE-2026-78445","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":9.8,"headline":"Windows Netlogon Remote Code Execution Vulnerability","id":"CVE-2026-41089","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":9.8,"headline":"Windows KDC Proxy Remote Code Execution Vulnerability","id":"CVE-2024-43639","kev_date_added":null,"published":"2024-11-12"},{"cvss_score":9.8,"headline":"Windows Network File System Remote Code Execution Vulnerability","id":"CVE-2023-24941","kev_date_added":null,"published":"2023-05-09"},{"cvss_score":9.8,"headline":"Windows Network File System Remote Code Execution Vulnerability","id":"CVE-2022-30136","kev_date_added":null,"published":"2022-06-15"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-01-01","vendors":["Microsoft"]},"summary":"An attacker can exploit a deserialization flaw in WSUS to escalate privileges on affected Windows Server systems.","url":"https://insights.sbomify.com/CVE-2023-35317/"}
