It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2019-13939 and fix it if it is affected.\n\nWhat it is: CVE-2019-13939 is a high-severity denial of service vulnerability in Siemens APOGEE MEC/MBC/PXC (P2), published on 16 Jan 2020. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-13939 in the wild and no public exploit code.\n\nAffected product: Siemens APOGEE MEC/MBC/PXC (P2). 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-2019-13939/ (Markdown: https://insights.sbomify.com/CVE-2019-13939/index.md)","id":"CVE-2019-13939","markdown":"https://insights.sbomify.com/CVE-2019-13939/index.md","name":"CVE-2019-13939","record":{"aliases":["GHSA-jpvr-c9fc-2r4h"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Siemens building automation","requires_auth":"none","summary":"An attacker can cause denial of service by sending crafted DHCP packets to change the device IP address to an invalid value.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"apogee_modular_building_controller_firmware","vendor":"siemens"},{"product":"apogee_modular_equiment_controller_firmware","vendor":"siemens"},{"product":"apogee_pxc_firmware","vendor":"siemens"},{"product":"capital_vstar","vendor":"siemens"},{"product":"desigo_pxc00-e.d_firmware","vendor":"siemens"},{"product":"desigo_pxc00-u_firmware","vendor":"siemens"},{"product":"desigo_pxc001-e.d_firmware","vendor":"siemens"},{"product":"desigo_pxc12-e.d_firmware","vendor":"siemens"},{"product":"desigo_pxc22-e.d_firmware","vendor":"siemens"},{"product":"desigo_pxc22.1-e.d_firmware","vendor":"siemens"},{"product":"desigo_pxc36.1-e.d_firmware","vendor":"siemens"},{"product":"desigo_pxc_firmware","vendor":"siemens"},{"product":"desigo_pxm20_firmware","vendor":"siemens"},{"product":"desigopxc100-e.d_firmware","vendor":"siemens"},{"product":"desigopxc128-u_firmware","vendor":"siemens"},{"product":"desigopxc200-e.d_firmware","vendor":"siemens"},{"product":"desigopxc50-e.d_firmware","vendor":"siemens"},{"product":"desigopxc64-u_firmware","vendor":"siemens"},{"product":"desigopxm20-e_firmware","vendor":"siemens"},{"product":"nucleus_net","vendor":"siemens"},{"product":"nucleus_readystart","vendor":"siemens"},{"product":"nucleus_rtos","vendor":"siemens"},{"product":"nucleus_safetycert","vendor":"siemens"},{"product":"nucleus_source_code","vendor":"siemens"},{"product":"simotics_connect_400_firmware","vendor":"siemens"},{"product":"talon_tc_firmware","vendor":"siemens"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability has been identified in APOGEE MEC/MBC/PXC (P2) (All versions \u003c V2.8.2), APOGEE PXC Compact (BACnet) (All versions \u003c V3.5.3), APOGEE PXC Compact (P2 Ethernet) (All versions \u003e= V2.8.2 \u003c V2.8.19), APOGEE PXC Modular (BACnet) (All versions \u003c V3.5.3), APOGEE PXC Modular (P2 Ethernet) (All versions \u003e= V2.8.2 \u003c V2.8.19), Capital Embedded AR Classic 431-422 (All versions), Capital Embedded AR Classic R20-11 (All versions \u003c V2303), Desigo PXC00-E.D (All versions \u003e= V2.3 \u003c V6.0.327), Desigo PXC00-U (All versions \u003e= V2.3x and \u003c V6.00.327), Desigo PXC001-E.D (All versions \u003e= V2.3 \u003c V6.0.327), Desigo PXC100-E.D (All versions \u003e= V2.3 \u003c V6.0.327), Desigo PXC12-E.D (All versions \u003e= V2.3 \u003c V6.0.327), Desigo PXC128-U (All versions \u003e= V2.3x and \u003c V6.00.327), Desigo PXC200-E.D (All versions \u003e= V2.3 \u003c V6.0.327), Desigo PXC22-E.D (All versions \u003e= V2.3 \u003c V6.0.327), Desigo PXC22.1-E.D (All versions \u003e= V2.3 \u003c V6.0.327), Desigo PXC36.1-E.D (All versions \u003e= V2.3 \u003c V6.0.327), Desigo PXC50-E.D (All versions \u003e= V2.3 \u003c V6.0.327), Desigo PXC64-U (All versions \u003e= V2.3x and \u003c V6.00.327), Desigo PXM20-E (All versions \u003e= V2.3 \u003c V6.0.327), Nucleus NET (All versions), Nucleus ReadyStart V3 (All versions \u003c V2017.02.3), Nucleus Source Code (All versions), SIMOTICS CONNECT 400 (All versions \u003c V0.3.0.330), TALON TC Compact (BACnet) (All versions \u003c V3.5.3), TALON TC Modular (BACnet) (All versions \u003c V3.5.3).
