An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-38371 and fix it if it is affected.\n\nWhat it is: CVE-2022-38371 is a high-severity denial of service vulnerability in Siemens APOGEE MBC (PPC) (BACnet), published on 11 Oct 2022. 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-2022-38371 in the wild and no public exploit code.\n\nAffected product: Siemens APOGEE MBC (PPC) (BACnet). 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-2022-38371/ (Markdown: https://insights.sbomify.com/CVE-2022-38371/index.md)","id":"CVE-2022-38371","markdown":"https://insights.sbomify.com/CVE-2022-38371/index.md","name":"CVE-2022-38371","record":{"aliases":["GHSA-59qg-qcpj-8hf9"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Building automation controller","requires_auth":"none","summary":"Remote attackers can cause denial of service on Siemens building automation devices by exploiting a memory leak in the FTP server during incomplete connections.","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_compact_firmware","vendor":"siemens"},{"product":"apogee_pxc_modular_firmware","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_pxc100-e.d_firmware","vendor":"siemens"},{"product":"desigo_pxc12-e.d_firmware","vendor":"siemens"},{"product":"desigo_pxc128-u_firmware","vendor":"siemens"},{"product":"desigo_pxc200-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_pxc50-e.d_firmware","vendor":"siemens"},{"product":"desigo_pxc64-u_firmware","vendor":"siemens"},{"product":"desigo_pxm20-e_firmware","vendor":"siemens"},{"product":"nucleus_net","vendor":"siemens"},{"product":"nucleus_readystart_v3","vendor":"siemens"},{"product":"nucleus_source_code","vendor":"siemens"},{"product":"talon_tc_compact_firmware","vendor":"siemens"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"A vulnerability has been identified in APOGEE MBC (PPC) (BACnet) (All versions), APOGEE MBC (PPC) (P2 Ethernet) (All versions), APOGEE MEC (PPC) (BACnet) (All versions), APOGEE MEC (PPC) (P2 Ethernet) (All versions), APOGEE PXC Compact (BACnet) (All versions \u003c V3.5.7), APOGEE PXC Compact (P2 Ethernet) (All versions \u003c V2.8.21), APOGEE PXC Modular (BACnet) (All versions \u003c V3.5.7), APOGEE PXC Modular (P2 Ethernet) (All versions \u003c V2.8.21), Desigo PXC00-E.D (All versions \u003e= V2.3 \u003c V6.30.37), Desigo PXC00-U (All versions \u003e= V2.3 \u003c V6.30.37), Desigo PXC001-E.D (All versions \u003e= V2.3 \u003c V6.30.37), Desigo PXC100-E.D (All versions \u003e= V2.3 \u003c V6.30.37), Desigo PXC12-E.D (All versions \u003e= V2.3 \u003c V6.30.37), Desigo PXC128-U (All versions \u003e= V2.3 \u003c V6.30.37), Desigo PXC200-E.D (All versions \u003e= V2.3 \u003c V6.30.37), Desigo PXC22-E.D (All versions \u003e= V2.3 \u003c V6.30.37), Desigo PXC22.1-E.D (All versions \u003e= V2.3 \u003c V6.30.37), Desigo PXC36.1-E.D (All versions \u003e= V2.3 \u003c V6.30.37), Desigo PXC50-E.D (All versions \u003e= V2.3 \u003c V6.30.37), Desigo PXC64-U (All versions \u003e= V2.3 \u003c V6.30.37), Desigo PXM20-E (All versions \u003e= V2.3 \u003c V6.30.37), Nucleus NET for Nucleus PLUS V1 (All versions \u003c V5.2a), Nucleus NET for Nucleus PLUS V2 (All versions \u003c V5.4), Nucleus ReadyStart V3 V2012 (All versions \u003c V2012.08.1), Nucleus ReadyStart V3 V2017 (All versions \u003c V2017.02.4), Nucleus Source Code (All versions including affected FTP server), TALON TC Compact (BACnet) (All versions \u003c V3.5.7), TALON TC Modular (BACnet) (All versions \u003c V3.5.7).
