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-2023-33920 in the wild and no public exploit code.\n\nAffected product: Siemens CP-8031 MASTER MODULE. 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-2023-33920/ (Markdown: https://insights.sbomify.com/CVE-2023-33920/index.md)","id":"CVE-2023-33920","markdown":"https://insights.sbomify.com/CVE-2023-33920/index.md","name":"CVE-2023-33920","record":{"aliases":["GHSA-mqj9-w9ch-6xmr"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Siemens master module","requires_auth":"none","summary":"Hardcoded root password hash allows attackers with physical access to gain root privileges via UART console on Siemens master modules.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"cpci85_firmware","vendor":"siemens"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"}],"description":"A vulnerability has been identified in CP-8031 MASTER MODULE (All versions \u003c CPCI85 V05), CP-8050 MASTER MODULE (All versions \u003c CPCI85 V05).
