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-2021-40363 and fix it if it is affected.\n\nWhat it is: CVE-2021-40363 is a high-severity vulnerability in Siemens SIMATIC PCS 7 V8.2, published on 9 Feb 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-2021-40363 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC PCS 7 V8.2. 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-2021-40363/ (Markdown: https://insights.sbomify.com/CVE-2021-40363/index.md)","id":"CVE-2021-40363","markdown":"https://insights.sbomify.com/CVE-2021-40363/index.md","name":"CVE-2021-40363","record":{"aliases":["GHSA-wg4m-r562-77pw"],"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 SCADA software","requires_auth":"low_privilege","summary":"An attacker can brute force credentials stored with weak encryption in project files to take over the system.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_pcs_7","vendor":"siemens"},{"product":"simatic_wincc","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-312","name":"Cleartext Storage of Sensitive Information"},{"id":"CWE-538","name":"Insertion of Sensitive Information into Externally-Accessible File or Directory"}],"description":"A vulnerability has been identified in SIMATIC PCS 7 V8.2 (All versions), SIMATIC PCS 7 V9.0 (All versions), SIMATIC PCS 7 V9.1 (All versions \u003c V9.1 SP1), SIMATIC WinCC V15 and earlier (All versions \u003c V15 SP1 Update 7), SIMATIC WinCC V16 (All versions \u003c V16 Update 5), SIMATIC WinCC V17 (All versions \u003c V17 Update 2), SIMATIC WinCC V17 (All versions \u003c= V17 Update 4), SIMATIC WinCC V7.4 (All versions \u003c V7.4 SP1 Update 19), SIMATIC WinCC V7.5 (All versions \u003c V7.5 SP2 Update 6).
