It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-31853 and fix it if it is affected.\n\nWhat it is: CVE-2021-31853 is a high-severity vulnerability in McAfee,LLC McAfee Drive Encryption (MDE), published on 10 Nov 2021. 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-2021-31853 in the wild and no public exploit code.\n\nAffected product: McAfee,LLC McAfee Drive Encryption (MDE). 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-2021-31853/ (Markdown: https://insights.sbomify.com/CVE-2021-31853/index.md)","id":"CVE-2021-31853","markdown":"https://insights.sbomify.com/CVE-2021-31853/index.md","name":"CVE-2021-31853","record":{"aliases":["GHSA-f925-j45v-vqqp"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"McAfee Drive Encryption","requires_auth":"low_privilege","summary":"Local attackers can execute arbitrary code and escalate privileges via DLL search order hijacking in McAfee Drive Encryption.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"drive_encryption","vendor":"mcafee"}],"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":"DLL Search Order Hijacking Vulnerability in McAfee Drive Encryption (MDE) prior to 7.3.0 HF2 (7.3.0.183) allows local users to execute arbitrary code and escalate privileges via execution from a compromised folder.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"MDE DLL Search Order Hijacking vulnerability","id":"CVE-2021-31853","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Code injection vulnerability in McAfee Agent","id":"CVE-2021-31854"},"packages":[],"prev":{"headline":"Cross-Site Scripting vulnerability in Policy Auditor","id":"CVE-2021-31852"},"products":["McAfee Drive Encryption (MDE)"],"published":"2021-11-10","related":[{"cvss_score":8.8,"headline":"Privilege Escalation vulnerability in McAfee Drive Encryption (MDE)","id":"CVE-2021-23893","kev_date_added":null,"published":"2021-10-01"},{"cvss_score":7,"headline":"Drive Encryption (MDE) - Authentication Bypass vulnerability","id":"CVE-2018-6686","kev_date_added":null,"published":"2018-07-27"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["McAfee,LLC"]},"summary":"Local attackers can execute arbitrary code and escalate privileges via DLL search order hijacking in McAfee Drive Encryption.","url":"https://insights.sbomify.com/CVE-2021-31853/"}
