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-2023-28829 in the wild and no public exploit code.\n\nAffected product: Siemens SIMATIC NET PC Software V14. 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-2023-28829/ (Markdown: https://insights.sbomify.com/CVE-2023-28829/index.md)","id":"CVE-2023-28829","markdown":"https://insights.sbomify.com/CVE-2023-28829/index.md","name":"CVE-2023-28829","record":{"aliases":["GHSA-cgxq-vv5m-p85q"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Siemens SCADA software","requires_auth":"high_privilege","summary":"Legacy OPC services in Siemens SCADA software lack modern authentication and encryption, allowing attackers to bypass security controls.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"simatic_net_pc_software","vendor":"siemens"},{"product":"simatic_pcs_7","vendor":"siemens"},{"product":"simatic_wincc","vendor":"siemens"},{"product":"sinaut_st7sc","vendor":"siemens"}],"cvss":{"score":3.9,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:H/UI:N/S:U/C:L/I:L/A:L/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-477","name":"Use of Obsolete Function"}],"description":"A vulnerability has been identified in SIMATIC NET PC Software V14 (All versions), SIMATIC NET PC Software V15 (All versions), SIMATIC PCS 7 V8.2 (All versions), SIMATIC PCS 7 V9.0 (All versions), SIMATIC PCS 7 V9.1 (All versions), SIMATIC WinCC (All versions \u003c V8.0), SINAUT Software ST7sc (All versions).
