An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2025-27480 and fix it if it is affected.\n\nWhat it is: CVE-2025-27480 is a high-severity use after free vulnerability in Microsoft Windows Server 2012, published on 8 Apr 2025. 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-2025-27480 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-2025-27480/ (Markdown: https://insights.sbomify.com/CVE-2025-27480/index.md)","id":"CVE-2025-27480","markdown":"https://insights.sbomify.com/CVE-2025-27480/index.md","name":"CVE-2025-27480","record":{"aliases":["GHSA-79xr-cjjw-p6f2"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Windows Server","requires_auth":"none","summary":"An unauthorized attacker can execute code over the network via a use-after-free flaw in the Windows Remote Desktop Gateway Service.","user_interaction":"not_required","vuln_class":"use_after_free"},"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"},{"product":"windows_server_2022_23h2","vendor":"microsoft"},{"product":"windows_server_2025","vendor":"microsoft"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Use after free in Remote Desktop Gateway Service allows an unauthorized attacker to execute code over a network.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-09-01","github_poc":2,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-09-01T10:49:54Z","kind":"github_poc","ref":"https://github.com/mrk336/CVE-2025-27480-The-Silent-Gateway-Risk","stars":1,"title":"Letting attackers run malicious code without needing a cracked password, user interaction, or even a foothold in your network.
