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-2019-6575 in the wild and no public exploit code.\n\nAffected product: Siemens Telecontrol Server Basic. 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-2019-6575/ (Markdown: https://insights.sbomify.com/CVE-2019-6575/index.md)","id":"CVE-2019-6575","markdown":"https://insights.sbomify.com/CVE-2019-6575/index.md","name":"CVE-2019-6575","record":{"aliases":["GHSA-q8p5-c986-46jg"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens SIMATIC OPC UA","requires_auth":"none","summary":"Unauthenticated remote attackers can cause denial of service or crash Siemens SIMATIC devices via crafted network packets on port 4840.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"opc_unified_architecture","vendor":"siemens"},{"product":"simatic_cp443-1_opc_ua_firmware","vendor":"siemens"},{"product":"simatic_et_200_open_controller_cpu_1515sp_pc2_firmware","vendor":"siemens"},{"product":"simatic_hmi_comfort_outdoor_panels_firmware","vendor":"siemens"},{"product":"simatic_hmi_ktp_mobile_panels_ktp400f_firmware","vendor":"siemens"},{"product":"simatic_hmi_ktp_mobile_panels_ktp700_firmware","vendor":"siemens"},{"product":"simatic_hmi_ktp_mobile_panels_ktp700f_firmware","vendor":"siemens"},{"product":"simatic_hmi_ktp_mobile_panels_ktp900_firmware","vendor":"siemens"},{"product":"simatic_hmi_ktp_mobile_panels_ktp900f_firmware","vendor":"siemens"},{"product":"simatic_ipc_diagmonitor_firmware","vendor":"siemens"},{"product":"simatic_net_pc_software_firmware","vendor":"siemens"},{"product":"simatic_rf188c_firmware","vendor":"siemens"},{"product":"simatic_rf600r_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_software_controller","vendor":"siemens"},{"product":"simatic_s7-1500f_firmware","vendor":"siemens"},{"product":"simatic_s7-1500s_firmware","vendor":"siemens"},{"product":"simatic_s7-1500t_firmware","vendor":"siemens"},{"product":"simatic_wincc_oa","vendor":"siemens"},{"product":"simatic_wincc_runtime_advanced","vendor":"siemens"},{"product":"simatic_wincc_runtime_comfort","vendor":"siemens"},{"product":"simatic_wincc_runtime_hsp_comfort","vendor":"siemens"},{"product":"simatic_wincc_runtime_mobile","vendor":"siemens"},{"product":"sinec-nms","vendor":"siemens"},{"product":"sinema_server","vendor":"siemens"},{"product":"sinumerik_opc_ua_server","vendor":"siemens"},{"product":"telecontrol_server_basic","vendor":"siemens"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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-755","name":"Improper Handling of Exceptional Conditions"},{"id":"CWE-248","name":"Uncaught Exception"}],"description":"A vulnerability has been identified in SIMATIC CP 443-1 OPC UA (All versions), SIMATIC ET 200SP Open Controller CPU 1515SP PC2 (incl.
