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-2021-23859 in the wild and no public exploit code.\n\nAffected product: Bosch AEC. 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-2021-23859/ (Markdown: https://insights.sbomify.com/CVE-2021-23859/index.md)","id":"CVE-2021-23859","markdown":"https://insights.sbomify.com/CVE-2021-23859/index.md","name":"CVE-2021-23859","record":{"aliases":["GHSA-w9fc-5fg9-fgph"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Bosch video management","requires_auth":"none","summary":"Unauthenticated attackers can crash a service via HTTP requests, potentially enabling further unauthenticated command execution in specific Bosch video management configurations.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"bosch","cpe":[{"product":"access_easy_controller_firmware","vendor":"bosch"},{"product":"access_professional_edition","vendor":"bosch"},{"product":"bosch_video_management_system","vendor":"bosch"},{"product":"building_integration_system","vendor":"bosch"},{"product":"video_recording_manager","vendor":"bosch"},{"product":"video_recording_manager_exporter","vendor":"bosch"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-755","name":"Improper Handling of Exceptional Conditions"},{"id":"CWE-703","name":"Improper Check or Handling of Exceptional Conditions"}],"description":"An unauthenticated attacker is able to send a special HTTP request, that causes a service to crash.
