It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-45231 in the wild and no public exploit code.\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-2021-45231/ (Markdown: https://insights.sbomify.com/CVE-2021-45231/index.md)","id":"CVE-2021-45231","markdown":"https://insights.sbomify.com/CVE-2021-45231/index.md","name":"CVE-2021-45231","record":{"aliases":["GHSA-c7c6-gf69-v976"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Endpoint security software","requires_auth":"low_privilege","summary":"A local attacker can escalate privileges by creating a specially crafted file, requiring prior low-privileged code execution on the system.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trendmicro","cpe":[{"product":"apex_one","vendor":"trendmicro"},{"product":"worry-free_business_security","vendor":"trendmicro"},{"product":"worry-free_business_security_services","vendor":"trendmicro"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","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-59","name":"Improper Link Resolution Before File Access"}],"description":"A link following privilege escalation vulnerability in Trend Micro Apex One (on-prem and SaaS) and Trend Micro Worry-Free Business Security (10.0 SP1 and Services) could allow a local attacker to create a specially crafted file with arbitrary content which could grant local privilege escalation on the affected system.
