An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2019-13946 and fix it if it is affected.\n\nWhat it is: CVE-2019-13946 is a high-severity denial of service vulnerability in Siemens Development/Evaluation Kits for PROFINET IO: DK Standard Ethernet Controller, published on 11 Feb 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-2019-13946 in the wild and no public exploit code.\n\nAffected product: Siemens Development/Evaluation Kits for PROFINET IO: DK Standard Ethernet Controller. 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-2019-13946/ (Markdown: https://insights.sbomify.com/CVE-2019-13946/index.md)","id":"CVE-2019-13946","markdown":"https://insights.sbomify.com/CVE-2019-13946/index.md","name":"CVE-2019-13946","record":{"aliases":["GHSA-8fqx-3qjr-87gw"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens PROFINET IO stack","requires_auth":"none","summary":"Remote attackers can cause denial of service on Siemens PROFINET IO devices by exhausting memory via diagnostic requests.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"dk_standard_ethernet_controller","vendor":"siemens"},{"product":"ek-ertec_200_firmware","vendor":"siemens"},{"product":"ek-ertec_200p_firmware","vendor":"siemens"},{"product":"im_154-3_pn_hf_firmware","vendor":"siemens"},{"product":"im_154-4_pn_hf_firmware","vendor":"siemens"},{"product":"profinet_driver","vendor":"siemens"},{"product":"ruggedcom_rm1224_firmware","vendor":"siemens"},{"product":"scalance_m-800_firmware","vendor":"siemens"},{"product":"scalance_s615_firmware","vendor":"siemens"},{"product":"scalance_w700_ieee_802.11n_firmware","vendor":"siemens"},{"product":"scalance_x-200irt_firmware","vendor":"siemens"},{"product":"scalance_x-300_firmware","vendor":"siemens"},{"product":"scalance_x-400_firmware","vendor":"siemens"},{"product":"scalance_xb-200_firmware","vendor":"siemens"},{"product":"scalance_xc-200_firmware","vendor":"siemens"},{"product":"scalance_xf-200_firmware","vendor":"siemens"},{"product":"scalance_xf-200ba_firmware","vendor":"siemens"},{"product":"scalance_xm-400_firmware","vendor":"siemens"},{"product":"scalance_xp-200_firmware","vendor":"siemens"},{"product":"scalance_xr-300wg_firmware","vendor":"siemens"},{"product":"scalance_xr524_firmware","vendor":"siemens"},{"product":"scalance_xr526_firmware","vendor":"siemens"},{"product":"scalance_xr528_firmware","vendor":"siemens"},{"product":"scalance_xr552_firmware","vendor":"siemens"},{"product":"simatic_cp_1604_firmware","vendor":"siemens"},{"product":"simatic_cp_1616_firmware","vendor":"siemens"},{"product":"simatic_cp_343-1_advanced_firmware","vendor":"siemens"},{"product":"simatic_cp_343-1_erpc_firmware","vendor":"siemens"},{"product":"simatic_cp_343-1_firmware","vendor":"siemens"},{"product":"simatic_cp_343-1_lean_firmware","vendor":"siemens"},{"product":"simatic_cp_443-1_advanced_firmware","vendor":"siemens"},{"product":"simatic_cp_443-1_firmware","vendor":"siemens"},{"product":"simatic_cp_443-1_opc_ua_firmware","vendor":"siemens"},{"product":"simatic_et200al_im_157-1_pn_firmware","vendor":"siemens"},{"product":"simatic_et200ecopn_firmware","vendor":"siemens"},{"product":"simatic_et200m_im153-4_pn_io_hf_firmware","vendor":"siemens"},{"product":"simatic_et200m_im153-4_pn_io_st_firmware","vendor":"siemens"},{"product":"simatic_et200mp_im155-5_pn_hf_firmware","vendor":"siemens"},{"product":"simatic_et200mp_im155-5_pn_st_firmware","vendor":"siemens"},{"product":"simatic_et200pro_firmware","vendor":"siemens"},{"product":"simatic_et200s_firmware","vendor":"siemens"},{"product":"simatic_et200sp_im155-6_pn_basic_firmware","vendor":"siemens"},{"product":"simatic_et200sp_im155-6_pn_hf_firmware","vendor":"siemens"},{"product":"simatic_et200sp_im155-6_pn_st_firmware","vendor":"siemens"},{"product":"simatic_ipc_support","vendor":"siemens"},{"product":"simatic_mv420_firmware","vendor":"siemens"},{"product":"simatic_mv440_firmware","vendor":"siemens"},{"product":"simatic_pn\\/pn_coupler_firmware","vendor":"siemens"},{"product":"simatic_rf180c_firmware","vendor":"siemens"},{"product":"simatic_rf182c_firmware","vendor":"siemens"},{"product":"simatic_rf600_firmware","vendor":"siemens"},{"product":"sinamics_dcp_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":"Profinet-IO (PNIO) stack versions prior V06.00 do not properly limit\ninternal resource allocation when multiple legitimate diagnostic package\nrequests are sent to the DCE-RPC interface.\nThis could lead to a denial of service condition due to lack of memory\nfor devices that include a vulnerable version of the stack.\n\nThe security vulnerability could be exploited by an attacker with network\naccess to an affected device.
