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-2021-42029 and fix it if it is affected.\n\nWhat it is: CVE-2021-42029 is a high-severity missing authorization vulnerability in Siemens SIMATIC STEP 7 (TIA Portal) V15, published on 12 Apr 2022. 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-2021-42029 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC STEP 7 (TIA Portal) V15. 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-2021-42029/ (Markdown: https://insights.sbomify.com/CVE-2021-42029/index.md)","id":"CVE-2021-42029","markdown":"https://insights.sbomify.com/CVE-2021-42029/index.md","name":"CVE-2021-42029","record":{"aliases":["GHSA-vp88-r9qc-vwrw"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Siemens TIA Portal","requires_auth":"low_privilege","summary":"An attacker with direct access to the web server can escalate privileges due to improper access control in Siemens TIA Portal engineering software.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_step_7","vendor":"siemens"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"A vulnerability has been identified in SIMATIC STEP 7 (TIA Portal) V15 (All versions), SIMATIC STEP 7 (TIA Portal) V16 (All versions \u003c V16 Update 5), SIMATIC STEP 7 (TIA Portal) V17 (All versions \u003c V17 Update 2).
