It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2021-36742 in the wild since at least 3 Nov 2021.\n\nAffected product: Trendmicro Apex One. 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-2021-36742/ (Markdown: https://insights.sbomify.com/CVE-2021-36742/index.md)","id":"CVE-2021-36742","markdown":"https://insights.sbomify.com/CVE-2021-36742/index.md","name":"CVE-2021-36742","record":{"aliases":["GHSA-h3hj-ff5j-498h"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Trend Micro endpoint security","requires_auth":"low_privilege","summary":"A local attacker with low-privileged code execution can escalate privileges on Trend Micro endpoint security products due to improper input validation.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trendmicro","cpe":[{"product":"apex_one","vendor":"trendmicro"},{"product":"officescan","vendor":"trendmicro"},{"product":"officescan_business_security","vendor":"trendmicro"},{"product":"worry-free_business_security","vendor":"trendmicro"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A improper input validation vulnerability in Trend Micro Apex One, Apex One as a Service, OfficeScan XG and Worry-Free Business Security 10.0 SP1 allows a local attacker to escalate privileges on affected installations.
