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-2025-24811 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC S7-1200 CPU 1211C AC/DC/Rly. 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-2025-24811/ (Markdown: https://insights.sbomify.com/CVE-2025-24811/index.md)","id":"CVE-2025-24811","markdown":"https://insights.sbomify.com/CVE-2025-24811/index.md","name":"CVE-2025-24811","record":{"aliases":["GHSA-jpqx-54f3-2q5j"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens PLC","requires_auth":"none","summary":"Attackers can cause a denial of service on Siemens SIMATIC S7-1200 PLCs, disrupting industrial control operations.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-404","name":"Improper Resource Shutdown or Release"}],"description":"A vulnerability has been identified in SIMATIC S7-1200 CPU 1211C AC/DC/Rly (6ES7211-1BE40-0XB0), SIMATIC S7-1200 CPU 1211C DC/DC/DC (6ES7211-1AE40-0XB0), SIMATIC S7-1200 CPU 1211C DC/DC/Rly (6ES7211-1HE40-0XB0), SIMATIC S7-1200 CPU 1212C AC/DC/Rly (6ES7212-1BE40-0XB0), SIMATIC S7-1200 CPU 1212C DC/DC/DC (6ES7212-1AE40-0XB0), SIMATIC S7-1200 CPU 1212C DC/DC/Rly (6ES7212-1HE40-0XB0), SIMATIC S7-1200 CPU 1212FC DC/DC/DC (6ES7212-1AF40-0XB0), SIMATIC S7-1200 CPU 1212FC DC/DC/Rly (6ES7212-1HF40-0XB0), SIMATIC S7-1200 CPU 1214C AC/DC/Rly (6ES7214-1BG40-0XB0), SIMATIC S7-1200 CPU 1214C DC/DC/DC (6ES7214-1AG40-0XB0), SIMATIC S7-1200 CPU 1214C DC/DC/Rly (6ES7214-1HG40-0XB0), SIMATIC S7-1200 CPU 1214FC DC/DC/DC (6ES7214-1AF40-0XB0), SIMATIC S7-1200 CPU 1214FC DC/DC/Rly (6ES7214-1HF40-0XB0), SIMATIC S7-1200 CPU 1215C AC/DC/Rly (6ES7215-1BG40-0XB0), SIMATIC S7-1200 CPU 1215C DC/DC/DC (6ES7215-1AG40-0XB0), SIMATIC S7-1200 CPU 1215C DC/DC/Rly (6ES7215-1HG40-0XB0), SIMATIC S7-1200 CPU 1215FC DC/DC/DC (6ES7215-1AF40-0XB0), SIMATIC S7-1200 CPU 1215FC DC/DC/Rly (6ES7215-1HF40-0XB0), SIMATIC S7-1200 CPU 1217C DC/DC/DC (6ES7217-1AG40-0XB0), SIPLUS S7-1200 CPU 1212 AC/DC/RLY (6AG1212-1BE40-2XB0), SIPLUS S7-1200 CPU 1212 AC/DC/RLY (6AG1212-1BE40-4XB0), SIPLUS S7-1200 CPU 1212 DC/DC/RLY (6AG1212-1HE40-2XB0), SIPLUS S7-1200 CPU 1212 DC/DC/RLY (6AG1212-1HE40-4XB0), SIPLUS S7-1200 CPU 1212C DC/DC/DC (6AG1212-1AE40-2XB0), SIPLUS S7-1200 CPU 1212C DC/DC/DC (6AG1212-1AE40-4XB0), SIPLUS S7-1200 CPU 1212C DC/DC/DC RAIL (6AG2212-1AE40-1XB0), SIPLUS S7-1200 CPU 1214 AC/DC/RLY (6AG1214-1BG40-2XB0), SIPLUS S7-1200 CPU 1214 AC/DC/RLY (6AG1214-1BG40-4XB0), SIPLUS S7-1200 CPU 1214 AC/DC/RLY (6AG1214-1BG40-5XB0), SIPLUS S7-1200 CPU 1214 DC/DC/DC (6AG1214-1AG40-2XB0), SIPLUS S7-1200 CPU 1214 DC/DC/DC (6AG1214-1AG40-4XB0), SIPLUS S7-1200 CPU 1214 DC/DC/DC (6AG1214-1AG40-5XB0), SIPLUS S7-1200 CPU 1214 DC/DC/RLY (6AG1214-1HG40-2XB0), SIPLUS S7-1200 CPU 1214 DC/DC/RLY (6AG1214-1HG40-4XB0), SIPLUS S7-1200 CPU 1214 DC/DC/RLY (6AG1214-1HG40-5XB0), SIPLUS S7-1200 CPU 1214C DC/DC/DC RAIL (6AG2214-1AG40-1XB0), SIPLUS S7-1200 CPU 1214FC DC/DC/DC (6AG1214-1AF40-5XB0), SIPLUS S7-1200 CPU 1214FC DC/DC/RLY (6AG1214-1HF40-5XB0), SIPLUS S7-1200 CPU 1215 AC/DC/RLY (6AG1215-1BG40-2XB0), SIPLUS S7-1200 CPU 1215 AC/DC/RLY (6AG1215-1BG40-4XB0), SIPLUS S7-1200 CPU 1215 AC/DC/RLY (6AG1215-1BG40-5XB0), SIPLUS S7-1200 CPU 1215 DC/DC/DC (6AG1215-1AG40-2XB0), SIPLUS S7-1200 CPU 1215 DC/DC/DC (6AG1215-1AG40-4XB0), SIPLUS S7-1200 CPU 1215 DC/DC/RLY (6AG1215-1HG40-2XB0), SIPLUS S7-1200 CPU 1215 DC/DC/RLY (6AG1215-1HG40-4XB0), SIPLUS S7-1200 CPU 1215 DC/DC/RLY (6AG1215-1HG40-5XB0), SIPLUS S7-1200 CPU 1215C DC/DC/DC (6AG1215-1AG40-5XB0), SIPLUS S7-1200 CPU 1215FC DC/DC/DC (6AG1215-1AF40-5XB0).
