It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-25247 and fix it if it is affected.\n\nWhat it is: CVE-2021-25247 is a high-severity vulnerability in Trend Micro HouseCall for Home Networks, published on 27 Jan 2021. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-25247 in the wild and no public exploit code.\n\nAffected product: Trend Micro HouseCall for Home Networks. 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-2021-25247/ (Markdown: https://insights.sbomify.com/CVE-2021-25247/index.md)","id":"CVE-2021-25247","markdown":"https://insights.sbomify.com/CVE-2021-25247/index.md","name":"CVE-2021-25247","record":{"aliases":["GHSA-v5j3-vp2m-wg9g"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Trend Micro HouseCall","requires_auth":"none","summary":"An attacker with local user access can exploit DLL hijacking to escalate privileges and execute arbitrary code on systems running Trend Micro HouseCall.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trendmicro","cpe":[{"product":"housecall_for_home_networks","vendor":"trendmicro"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-427","name":"Uncontrolled Search Path Element"}],"description":"A DLL hijacking vulnerability Trend Micro HouseCall for Home Networks version 5.3.1063 and below could allow an attacker to use a malicious DLL to escalate privileges and perform arbitrary code execution.
