SIPLUS variants), published on 20 Mar 2018. 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-2018-4843 and fix it if it is affected.\n\nWhat it is: CVE-2018-4843 is a medium-severity vulnerability in Siemens SIMATIC CP 343-1 (incl. SIPLUS variants), published on 20 Mar 2018. 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-2018-4843 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC CP 343-1 (incl. SIPLUS variants). 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-2018-4843/ (Markdown: https://insights.sbomify.com/CVE-2018-4843/index.md)","id":"CVE-2018-4843","markdown":"https://insights.sbomify.com/CVE-2018-4843/index.md","name":"CVE-2018-4843","record":{"aliases":["GHSA-2cg6-w8mm-22rg"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Siemens SIMATIC PLC","requires_auth":"none","summary":"Attackers can cause a denial of service on Siemens SIMATIC PLCs and communication processors via improper input validation.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_cp_343-1_firmware","vendor":"siemens"},{"product":"simatic_cp_443-1_firmware","vendor":"siemens"},{"product":"simatic_s7-1500_firmware","vendor":"siemens"},{"product":"simatic_s7-300_firmware","vendor":"siemens"},{"product":"simatic_s7-400_h_v6_firmware","vendor":"siemens"},{"product":"simatic_s7-400_pn\\/dp_v6_firmware","vendor":"siemens"},{"product":"simatic_s7-400_pn\\/dp_v7_firmware","vendor":"siemens"},{"product":"simatic_s7-410_firmware","vendor":"siemens"},{"product":"simatic_winac_rtx_2010_firmware","vendor":"siemens"},{"product":"sinumerik_828d_firmware","vendor":"siemens"},{"product":"softnet_pn-io_linux_firmware","vendor":"siemens"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/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-20","name":"Improper Input Validation"}],"description":"A vulnerability has been identified in  SIMATIC S7-400 CPU 414-3 PN/DP V7 (All versions \u003c V7.0.3),  SIMATIC S7-400 CPU 414F-3 PN/DP V7 (All versions \u003c V7.0.3),  SIMATIC S7-400 CPU 416-3 PN/DP V7 (All versions \u003c V7.0.3),  SIMATIC S7-400 CPU 416F-3 PN/DP V7 (All versions \u003c V7.0.3), SIMATIC CP 343-1 (incl.
