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-2020-25241 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC MV400 family. 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-2020-25241/ (Markdown: https://insights.sbomify.com/CVE-2020-25241/index.md)","id":"CVE-2020-25241","markdown":"https://insights.sbomify.com/CVE-2020-25241/index.md","name":"CVE-2020-25241","record":{"aliases":["GHSA-hgp9-8qfr-qjj7"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial vision system","requires_auth":"none","summary":"An attacker can terminate arbitrary TCP sessions by exploiting improper validation of TCP RST sequence numbers in SIMATIC MV400 devices.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_mv420_sr-b_body_firmware","vendor":"siemens"},{"product":"simatic_mv420_sr-b_firmware","vendor":"siemens"},{"product":"simatic_mv420_sr-p_body_firmware","vendor":"siemens"},{"product":"simatic_mv420_sr-p_firmware","vendor":"siemens"},{"product":"simatic_mv440_hr_firmware","vendor":"siemens"},{"product":"simatic_mv440_sr_firmware","vendor":"siemens"},{"product":"simatic_mv440_ur_firmware","vendor":"siemens"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-129","name":"Improper Validation of Array Index"},{"id":"CWE-1285","name":"Improper Validation of Specified Index, Position, or Offset in Input"}],"description":"A vulnerability has been identified in SIMATIC MV400 family (All Versions \u003c V7.0.6).
