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-2023-46284 in the wild and no public exploit code.\n\nAffected product: Siemens Opcenter Execution Foundation. 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-2023-46284/ (Markdown: https://insights.sbomify.com/CVE-2023-46284/index.md)","id":"CVE-2023-46284","markdown":"https://insights.sbomify.com/CVE-2023-46284/index.md","name":"CVE-2023-46284","record":{"aliases":["GHSA-f2hj-x395-x532"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens industrial software","requires_auth":"none","summary":"An attacker can crash Siemens industrial applications via out-of-bounds write on specific ports, causing denial of service until auto-restart.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"opcenter_quality","vendor":"siemens"},{"product":"simatic_pcs_neo","vendor":"siemens"},{"product":"sinumerik_integrate_runmyhmi_\\/automotive","vendor":"siemens"},{"product":"totally_integrated_automation_portal","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-787","name":"Out-of-bounds Write"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A vulnerability has been identified in Opcenter Execution Foundation (All versions \u003c V2407), Opcenter Quality (All versions \u003c V2312), SIMATIC PCS neo (All versions \u003c V4.1), SINEC NMS (All versions \u003c V2.0 SP1), Totally Integrated Automation Portal (TIA Portal) V14 (All versions), Totally Integrated Automation Portal (TIA Portal) V15.1 (All versions), Totally Integrated Automation Portal (TIA Portal) V16 (All versions), Totally Integrated Automation Portal (TIA Portal) V17 (All versions \u003c V17 Update 8), Totally Integrated Automation Portal (TIA Portal) V18 (All versions \u003c V18 Update 3).
