An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-27389 in the wild and no public exploit code.\n\nAffected product: Siemens Opcenter Quality. 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-2021-27389/ (Markdown: https://insights.sbomify.com/CVE-2021-27389/index.md)","id":"CVE-2021-27389","markdown":"https://insights.sbomify.com/CVE-2021-27389/index.md","name":"CVE-2021-27389","record":{"aliases":["GHSA-wrq7-4jj9-f6rc"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Siemens Quality Management","requires_auth":"none","summary":"Siemens Opcenter Quality and QMS Automotive ship with an unprotected private signing key, allowing attackers to bypass security controls or access data.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"opcenter_quality","vendor":"siemens"},{"product":"qms_automotive","vendor":"siemens"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-321","name":"Use of Hard-coded Cryptographic Key"}],"description":"A vulnerability has been identified in Opcenter Quality (All versions \u003c V12.2), QMS Automotive (All versions \u003c V12.30).
