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-2024-49138 and fix it if it is affected.\n\nWhat it is: CVE-2024-49138 is a high-severity memory corruption vulnerability in Microsoft Windows 10 1507, published on 10 Dec 2024. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2024-49138 in the wild since at least 10 Dec 2024.\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-2024-49138/ (Markdown: https://insights.sbomify.com/CVE-2024-49138/index.md)","id":"CVE-2024-49138","markdown":"https://insights.sbomify.com/CVE-2024-49138/index.md","name":"CVE-2024-49138","record":{"aliases":["GHSA-h4hx-5g7m-p3hc"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows CLFS Driver","requires_auth":"low_privilege","summary":"A heap-based buffer overflow in the Windows Common Log File System driver allows attackers to escalate privileges on affected systems.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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":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-122","name":"Heap-based Buffer Overflow"}],"description":"Windows Common Log File System Driver Elevation of Privilege Vulnerability","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2025-01-15","github_poc":13,"max_poc_stars":271,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-01-15T00:43:37Z","kind":"github_poc","ref":"https://github.com/MrAle98/CVE-2024-49138-POC","stars":271,"title":"POC exploit for CVE-2024-49138"},{"date":"2026-03-09T16:36:19Z","kind":"github_poc","ref":"https://github.com/Zedocun/soc-investigation-powershell-edrfreeze","stars":1,"title":"SOC investigation of CVE-2024-49138 exploitation alert involving PowerShell, EDRFreeze execution, and defense evasion behavior in a simulated environment."},{"date":"2025-01-21T01:50:34Z","kind":"github_poc","ref":"https://github.com/bananoname/CVE-2024-49138-POC","stars":0,"title":null},{"date":"2025-03-14T11:32:13Z","kind":"github_poc","ref":"https://github.com/DeividasTerechovas/SOC335-CVE-2024-49138-Exploitation-Detected","stars":0,"title":null},{"date":"2025-04-22","kind":"exploitdb","ref":"52270","stars":null,"title":"Microsoft Windows 11 23h2 - CLFS.sys Elevation of Privilege"},{"date":"2025-04-23T18:20:19Z","kind":"github_poc","ref":"https://github.com/CyprianAtsyor/letsdefend-cve-2024-49138-investigation","stars":0,"title":"Hands-on SOC investigation of CVE-2024-49138 using LetsDefend, VirusTotal, Hybrid Analysis, TrueFort, and ChatGPT."},{"date":"2025-05-04T19:05:49Z","kind":"github_poc","ref":"https://github.com/Bridg3Ops/SOC335-CVE-2024-49138-Exploitation-Detected","stars":0,"title":null},{"date":"2025-06-12T12:40:36Z","kind":"github_poc","ref":"https://github.com/onixgod/SOC335-Event-ID-313-CVE-2024-49138-Exploitation-Detected--Lest-Defend-Writeup","stars":0,"title":"In this lab I walked through an end-to-end intrusion that began with an external RDP break-in, used a brand-new CLFS privilege-escalation exploit (CVE-2024–49138), and ended with SYSTEM-level cloud credential harvesting.
