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-2021-21518 in the wild and no public exploit code.\n\nAffected product: Dell SupportAssist Client. 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-2021-21518/ (Markdown: https://insights.sbomify.com/CVE-2021-21518/index.md)","id":"CVE-2021-21518","markdown":"https://insights.sbomify.com/CVE-2021-21518/index.md","name":"CVE-2021-21518","record":{"aliases":["GHSA-m78j-wwfx-36xp"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Dell SupportAssist Client","requires_auth":"low_privilege","summary":"A local attacker can exploit a DLL injection flaw in Dell SupportAssist to execute arbitrary code with SYSTEM privileges.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"dell","cpe":[{"product":"supportassist_client_promanage","vendor":"dell"},{"product":"supportassist_for_business_pcs","vendor":"dell"},{"product":"supportassist_for_home_pcs","vendor":"dell"}],"cvss":{"score":7.8,"severity":"high","source":"cna","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-427","name":"Uncontrolled Search Path Element"}],"description":"Dell SupportAssist Client for Consumer PCs versions 3.7.x, 3.6.x, 3.4.x, 3.3.x, Dell SupportAssist Client for Business PCs versions 2.0.x, 2.1.x, 2.2.x, and Dell SupportAssist Client ProManage 1.x contain a DLL injection vulnerability in the Costura Fody plugin.
