It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-23016 exists.\n\nAffected product: FastCGI fcgi. 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-2025-23016/ (Markdown: https://insights.sbomify.com/CVE-2025-23016/index.md)","id":"CVE-2025-23016","markdown":"https://insights.sbomify.com/CVE-2025-23016/index.md","name":"CVE-2025-23016","record":{"aliases":["AZL-55397","AZL-55443","BELL-CVE-2025-23016","DEBIAN-CVE-2025-23016","DLA-4329-1","GHSA-9825-56cx-cfg6","MGASA-2025-0144","OESA-2025-1475","OESA-2025-2779","SUSE-SU-2025:02369-1","SUSE-SU-2025:02372-1","UBUNTU-CVE-2025-23016","USN-7486-1","openSUSE-SU-2025:15348-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"FastCGI library","requires_auth":"none","summary":"An integer overflow in the FastCGI library allows attackers to trigger a heap-based buffer overflow via crafted IPC socket data, potentially leading to code execution or denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"FastCGI fcgi2 (aka fcgi) 2.x through 2.4.4 has an integer overflow (and resultant heap-based buffer overflow) via crafted nameLen or valueLen values in data to the IPC socket.
