An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2019-10923 and fix it if it is affected.\n\nWhat it is: CVE-2019-10923 is a high-severity denial of service vulnerability in Siemens Development/Evaluation Kits for PROFINET IO: DK Standard Ethernet Controller, published on 10 Oct 2019. 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-2019-10923 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-2019-10923/ (Markdown: https://insights.sbomify.com/CVE-2019-10923/index.md)","id":"CVE-2019-10923","markdown":"https://insights.sbomify.com/CVE-2019-10923/index.md","name":"CVE-2019-10923","record":{"aliases":["GHSA-gm9h-7xvc-jg2f"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens industrial controllers","requires_auth":"none","summary":"An attacker can cause a denial of service by disrupting real-time synchronization in Siemens industrial network devices.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"cp1604_firmware","vendor":"siemens"},{"product":"cp1616_firmware","vendor":"siemens"},{"product":"dk_standard_ethernet_controller_firmware","vendor":"siemens"},{"product":"ek-ertec_200_firmware","vendor":"siemens"},{"product":"ek-ertec_200p_firmware","vendor":"siemens"},{"product":"scalance_x-200irt_firmware","vendor":"siemens"},{"product":"simatic_et_200ecopn_firmware","vendor":"siemens"},{"product":"simatic_et_200m_firmware","vendor":"siemens"},{"product":"simatic_et_200s_firmware","vendor":"siemens"},{"product":"simatic_pn\\/pn_coupler_6es7158-3ad01-0xa0_firmware","vendor":"siemens"},{"product":"simatic_s7-300_cpu_312_ifm_firmware","vendor":"siemens"},{"product":"simatic_s7-300_cpu_313_firmware","vendor":"siemens"},{"product":"simatic_s7-300_cpu_314_firmware","vendor":"siemens"},{"product":"simatic_s7-300_cpu_314_ifm_firmware","vendor":"siemens"},{"product":"simatic_s7-300_cpu_315-2_dp_firmware","vendor":"siemens"},{"product":"simatic_s7-300_cpu_315_firmware","vendor":"siemens"},{"product":"simatic_s7-300_cpu_316-2_dp_firmware","vendor":"siemens"},{"product":"simatic_s7-300_cpu_318-2_firmware","vendor":"siemens"},{"product":"simatic_s7-300_cpu_firmware","vendor":"siemens"},{"product":"simatic_s7-400_dp_v7_firmware","vendor":"siemens"},{"product":"simatic_s7-400_pn_v7_firmware","vendor":"siemens"},{"product":"simatic_s7-400_v6_firmware","vendor":"siemens"},{"product":"simatic_winac_rtx_\\(f\\)_firmware","vendor":"siemens"},{"product":"simotion_firmware","vendor":"siemens"},{"product":"sinamics_dcm_firmware","vendor":"siemens"},{"product":"sinamics_dcp_firmware","vendor":"siemens"},{"product":"sinamics_g110m_firmware","vendor":"siemens"},{"product":"sinamics_g120_firmware","vendor":"siemens"},{"product":"sinamics_g130_firmware","vendor":"siemens"},{"product":"sinamics_g150_firmware","vendor":"siemens"},{"product":"sinamics_gh150_firmware","vendor":"siemens"},{"product":"sinamics_gl150_firmware","vendor":"siemens"},{"product":"sinamics_gm150_firmware","vendor":"siemens"},{"product":"sinamics_s110_firmware","vendor":"siemens"},{"product":"sinamics_s120_firmware","vendor":"siemens"},{"product":"sinamics_s150_firmware","vendor":"siemens"},{"product":"sinamics_sl150_firmware","vendor":"siemens"},{"product":"sinamics_sm120_firmware","vendor":"siemens"},{"product":"sinumerik_828d","vendor":"siemens"},{"product":"sinumerik_840d_sl","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":"An attacker with network access to an affected product may cause a denial of service condition by breaking the real-time synchronization (IRT) of the affected installation.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in Development/Evaluation Kits for PROFINET IO: DK Standard Ethernet Controller","id":"CVE-2019-10923","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2019"},"n_packages":0,"n_references":2,"next":{"headline":"Deserialization in LOGO!
