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-2020-7586 and fix it if it is affected.\n\nWhat it is: CVE-2020-7586 is a high-severity memory corruption vulnerability in Siemens SIMATIC PCS 7 V8.2 and earlier, published on 10 Jun 2020. 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-2020-7586 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC PCS 7 V8.2 and earlier. 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-2020-7586/ (Markdown: https://insights.sbomify.com/CVE-2020-7586/index.md)","id":"CVE-2020-7586","markdown":"https://insights.sbomify.com/CVE-2020-7586/index.md","name":"CVE-2020-7586","record":{"aliases":["GHSA-wggc-468x-3c9v"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Siemens industrial automation","requires_auth":"low_privilege","summary":"A local attacker can exploit a buffer overflow in Siemens industrial software to cause denial of service and access confidential information.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_pcs_7","vendor":"siemens"},{"product":"simatic_process_device_manager","vendor":"siemens"},{"product":"simatic_step_7","vendor":"siemens"},{"product":"sinamics_starter","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-787","name":"Out-of-bounds Write"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A vulnerability has been identified in SIMATIC PCS 7 V8.2 and earlier (All versions), SIMATIC PCS 7 V9.0 (All versions \u003c V9.0 SP3), SIMATIC PDM (All versions \u003c V9.2), SIMATIC STEP 7 V5.X (All versions \u003c V5.6 SP2 HF3), SINAMICS STARTER (containing STEP 7 OEM version) (All versions \u003c V5.4 HF2).
