Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-40359 and fix it if it is affected.\n\nWhat it is: CVE-2021-40359 is a high-severity path traversal vulnerability in Siemens OpenPCS 7 V8.2, published on 9 Nov 2021. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-40359 in the wild and no public exploit code.\n\nAffected product: Siemens OpenPCS 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-2021-40359/ (Markdown: https://insights.sbomify.com/CVE-2021-40359/index.md)","id":"CVE-2021-40359","markdown":"https://insights.sbomify.com/CVE-2021-40359/index.md","name":"CVE-2021-40359","record":{"aliases":["GHSA-6gc3-vp66-4fcm"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens SIMATIC software","requires_auth":"low_privilege","summary":"Attackers can read critical files outside restricted directories via path traversal in Siemens SIMATIC software during file downloads.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_batch","vendor":"siemens"},{"product":"simatic_net_pc","vendor":"siemens"},{"product":"simatic_route_control","vendor":"siemens"},{"product":"simatic_wincc","vendor":"siemens"},{"product":"simaticpcs_7","vendor":"siemens"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A vulnerability has been identified in OpenPCS 7 V8.2 (All versions), OpenPCS 7 V9.0 (All versions \u003c V9.0 Upd4), OpenPCS 7 V9.1 (All versions), SIMATIC BATCH V8.2 (All versions), SIMATIC BATCH V9.0 (All versions), SIMATIC BATCH V9.1 (All versions), SIMATIC NET PC Software V14 (All versions), SIMATIC NET PC Software V15 (All versions), SIMATIC NET PC Software V16 (All versions \u003c V16 Update 6), SIMATIC NET PC Software V17 (All versions \u003c V17 SP1), SIMATIC PCS 7 V8.2 (All versions), SIMATIC PCS 7 V9.0 (All versions \u003c V9.0 SP3 UC04), SIMATIC PCS 7 V9.1 (All versions \u003c V9.1 SP1), SIMATIC Route Control V8.2 (All versions), SIMATIC Route Control V9.0 (All versions), SIMATIC Route Control V9.1 (All versions), 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 V7.4 (All versions \u003c V7.4 SP1 Update 19), SIMATIC WinCC V7.5 (All versions \u003c V7.5 SP2 Update 5).
