It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2020-24557 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-2020-24557/ (Markdown: https://insights.sbomify.com/CVE-2020-24557/index.md)","id":"CVE-2020-24557","markdown":"https://insights.sbomify.com/CVE-2020-24557/index.md","name":"CVE-2020-24557","record":{"aliases":["GHSA-rf37-cmcm-645m"],"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":"Attackers with low-privileged code execution can manipulate product folders to disable security and escalate privileges on Windows systems.","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"}],"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":[],"description":"A vulnerability in Trend Micro Apex One and Worry-Free Business Security 10.0 SP1 on Microsoft Windows may allow an attacker to manipulate a particular product folder to disable the security temporarily, abuse a specific Windows function and attain privilege escalation.
