Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2025-54918 and fix it if it is affected.\n\nWhat it is: CVE-2025-54918 is a high-severity vulnerability in Microsoft Windows 10 1507, published on 9 Sep 2025. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-54918 in the wild and no public exploit code.\n\nAffected product: Microsoft Windows 10 1507. 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-2025-54918/ (Markdown: https://insights.sbomify.com/CVE-2025-54918/index.md)","id":"CVE-2025-54918","markdown":"https://insights.sbomify.com/CVE-2025-54918/index.md","name":"CVE-2025-54918","record":{"aliases":["GHSA-75v4-rj2v-3f53"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows OS","requires_auth":"low_privilege","summary":"An authorized attacker can elevate privileges over the network due to improper authentication in Windows NTLM.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10_1507","vendor":"microsoft"},{"product":"windows_10_1607","vendor":"microsoft"},{"product":"windows_10_1809","vendor":"microsoft"},{"product":"windows_10_21h2","vendor":"microsoft"},{"product":"windows_10_22h2","vendor":"microsoft"},{"product":"windows_11_22h2","vendor":"microsoft"},{"product":"windows_11_23h2","vendor":"microsoft"},{"product":"windows_11_24h2","vendor":"microsoft"},{"product":"windows_server_2008","vendor":"microsoft"},{"product":"windows_server_2012","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"},{"product":"windows_server_2022","vendor":"microsoft"},{"product":"windows_server_2022_23h2","vendor":"microsoft"},{"product":"windows_server_2025","vendor":"microsoft"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/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-287","name":"Improper Authentication"}],"description":"Improper authentication in Windows NTLM allows an authorized attacker to elevate privileges over a network.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-09-17","github_poc":2,"max_poc_stars":65,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-01-12T17:54:05Z","kind":"github_poc","ref":"https://github.com/Wh0am123/CVE-2025-54918-POC","stars":65,"title":"POC for CVE-2025-54918 and a technical demonstration."},{"date":"2025-09-17T02:54:44Z","kind":"github_poc","ref":"https://github.com/mrk336/From-Foothold-to-Domain-Admin-Weaponizing-CVE-2025-54918-in-Real-World-DevOps","stars":5,"title":"Simulated exploitation and mitigation of CVE-2025-54918 (Windows NTLM flaw).
