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-2022-37012 in the wild and no public exploit code.\n\nAffected product: Unified Automation OPC UA C++ Demo Server. 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-2022-37012/ (Markdown: https://insights.sbomify.com/CVE-2022-37012/index.md)","id":"CVE-2022-37012","markdown":"https://insights.sbomify.com/CVE-2022-37012/index.md","name":"CVE-2022-37012","record":{"aliases":["GHSA-5xp2-x7qr-wjrx"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OPC UA C++ Demo Server","requires_auth":"none","summary":"Remote attackers can cause a denial-of-service condition in Unified Automation OPC UA C++ Demo Server by sending crafted messages that corrupt reference counts.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"opc_ua_c\\+\\+_demo_server","vendor":"unified-automation"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-911","name":"Improper Update of Reference Count"}],"description":"This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Unified Automation OPC UA C++ Demo Server 1.7.6-537.
