An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2019-19300 and fix it if it is affected.\n\nWhat it is: CVE-2019-19300 is a high-severity denial of service vulnerability in Siemens Development/Evaluation Kits for PROFINET IO: EK-ERTEC 200, published on 14 Apr 2020. 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-2019-19300 in the wild and no public exploit code.\n\nAffected product: Siemens Development/Evaluation Kits for PROFINET IO: EK-ERTEC 200. 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-2019-19300/ (Markdown: https://insights.sbomify.com/CVE-2019-19300/index.md)","id":"CVE-2019-19300","markdown":"https://insights.sbomify.com/CVE-2019-19300/index.md","name":"CVE-2019-19300","record":{"aliases":["GHSA-vwm3-cv6h-hrm3"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens SIMATIC PLC","requires_auth":"none","summary":"Attackers can cause a denial of service in Siemens SIMATIC and PROFINET devices by exploiting a resource exhaustion vulnerability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"ktk_ate530s_firmware","vendor":"siemens"},{"product":"sidoor_atd430w_firmware","vendor":"siemens"},{"product":"sidoor_ate530s_coated_firmware","vendor":"siemens"},{"product":"sidoor_ate531s_firmware","vendor":"siemens"},{"product":"simatic_et200mp_im155-5_pn_hf_firmware","vendor":"siemens"},{"product":"simatic_et200sp_im155-6_mf_hf_firmware","vendor":"siemens"},{"product":"simatic_et200sp_im155-6_pn\\/2_hf_firmware","vendor":"siemens"},{"product":"simatic_et200sp_im155-6_pn_ha_firmware","vendor":"siemens"},{"product":"simatic_et200sp_im155-6_pn_hf_firmware","vendor":"siemens"},{"product":"simatic_et_200sp_open_controller_cpu_1515sp_pc2_firmware","vendor":"siemens"},{"product":"simatic_et_200sp_open_controller_cpu_1515sp_pc_firmware","vendor":"siemens"},{"product":"simatic_micro-drive_pdc_firmware","vendor":"siemens"},{"product":"simatic_pn\\/pn_coupler_firmware","vendor":"siemens"},{"product":"simatic_s7-1500","vendor":"siemens"},{"product":"simatic_s7-1500_cpu_1511-1_pn_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_cpu_1511f-1_pn_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_cpu_1513-1_pn_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_cpu_1513f-1_pn_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_cpu_1515-2_pn_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_cpu_1515f-2_pn_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_cpu_1516-3_pn\\/dp_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_cpu_1516f-3_pn\\/dp_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_cpu_1517-3_pn\\/dp_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_cpu_1517f-3_pn\\/dp_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_cpu_1518-4_pn\\/dp_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_cpu_1518f-4_pn\\/dp_firmware","vendor":"siemens"},{"product":"simatic_s7-300_cpu_firmware","vendor":"siemens"},{"product":"simatic_s7-400_pn\\/dp_firmware","vendor":"siemens"},{"product":"simatic_s7-410_cpu_firmware","vendor":"siemens"},{"product":"simatic_tdc_cp51m1_firmware","vendor":"siemens"},{"product":"simatic_tdc_cpu555_firmware","vendor":"siemens"},{"product":"simatic_winac_rtx_\\(f\\)_2010_firmware","vendor":"siemens"},{"product":"sinamics_s\\/g_control_unit_firmware","vendor":"siemens"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A vulnerability has been identified in Development/Evaluation Kits for PROFINET IO: EK-ERTEC 200, Development/Evaluation Kits for PROFINET IO: EK-ERTEC 200P, KTK ATE530S, SIDOOR ATD430W, SIDOOR ATE530S COATED, SIDOOR ATE531S, SIMATIC ET 200AL IM 157-1 PN (6ES7157-1AB00-0AB0), SIMATIC ET 200eco PN, AI 8xRTD/TC, M12-L (6ES7144-6JF00-0BB0), SIMATIC ET 200eco PN, CM 4x IO-Link, M12-L (6ES7148-6JE00-0BB0), SIMATIC ET 200eco PN, CM 8x IO-Link, M12-L (6ES7148-6JG00-0BB0), SIMATIC ET 200eco PN, CM 8x IO-Link, M12-L (6ES7148-6JJ00-0BB0), SIMATIC ET 200eco PN, DI 16x24VDC, M12-L (6ES7141-6BH00-0BB0), SIMATIC ET 200eco PN, DI 8x24VDC, M12-L (6ES7141-6BG00-0BB0), SIMATIC ET 200eco PN, DIQ 16x24VDC/2A, M12-L (6ES7143-6BH00-0BB0), SIMATIC ET 200eco PN, DQ 8x24VDC/0,5A, M12-L (6ES7142-6BG00-0BB0), SIMATIC ET 200eco PN, DQ 8x24VDC/2A, M12-L (6ES7142-6BR00-0BB0), SIMATIC ET 200MP IM 155-5 PN HF (6ES7155-5AA00-0AC0), SIMATIC ET 200pro IM 154-8 PN/DP CPU (6ES7154-8AB01-0AB0), SIMATIC ET 200pro IM 154-8F PN/DP CPU (6ES7154-8FB01-0AB0), SIMATIC ET 200pro IM 154-8FX PN/DP CPU (6ES7154-8FX00-0AB0), SIMATIC ET 200S IM 151-8 PN/DP CPU (6ES7151-8AB01-0AB0), SIMATIC ET 200S IM 151-8F PN/DP CPU (6ES7151-8FB01-0AB0), SIMATIC ET 200SP IM 155-6 MF HF (6ES7155-6MU00-0CN0), SIMATIC ET 200SP IM 155-6 PN HA (incl.
