Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-27392 in the wild and no public exploit code.\n\nAffected product: Siemens Siveillance Video Open Network Bridge. 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-2021-27392/ (Markdown: https://insights.sbomify.com/CVE-2021-27392/index.md)","id":"CVE-2021-27392","markdown":"https://insights.sbomify.com/CVE-2021-27392/index.md","name":"CVE-2021-27392","record":{"aliases":["GHSA-5346-4j79-hf8j"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Video surveillance software","requires_auth":"low_privilege","summary":"An authenticated remote attacker can retrieve and decrypt stored user credentials due to a hard-coded encryption key in the Open Network Bridge.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"siemens","cpe":[{"product":"siveillance_video_open_network_bridge","vendor":"siemens"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"},{"id":"CWE-321","name":"Use of Hard-coded Cryptographic Key"}],"description":"A vulnerability has been identified in Siveillance Video Open Network Bridge (2020 R3), Siveillance Video Open Network Bridge (2020 R2), Siveillance Video Open Network Bridge (2020 R1), Siveillance Video Open Network Bridge (2019 R3), Siveillance Video Open Network Bridge (2019 R2), Siveillance Video Open Network Bridge (2019 R1), Siveillance Video Open Network Bridge (2018 R3), Siveillance Video Open Network Bridge (2018 R2).
