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-2021-31838 in the wild and no public exploit code.\n\nAffected product: McAfee,LLC MVISION EDR. 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-2021-31838/ (Markdown: https://insights.sbomify.com/CVE-2021-31838/index.md)","id":"CVE-2021-31838","markdown":"https://insights.sbomify.com/CVE-2021-31838/index.md","name":"CVE-2021-31838","record":{"aliases":["GHSA-hg4j-hgh6-fp6f"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"MVISION EDR client","requires_auth":"high_privilege","summary":"An authenticated administrator can execute arbitrary commands on the EDR client via PowerShell, requiring an upgrade to mitigate.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"mvision_edr","vendor":"mcafee"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"A command injection vulnerability in MVISION EDR (MVEDR) prior to 3.4.0 allows an authenticated MVEDR administrator to trigger the EDR client to execute arbitrary commands through PowerShell using the EDR functionality 'execute reaction'.","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":"Command injection through environment variable in MVISION EDR","id":"CVE-2021-31838","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Incorrect permissions on McAfee Agent for Windows event folder","id":"CVE-2021-31839"},"packages":[],"prev":{"headline":"Out of bounds write vulnerability in McAfee GetSusp","id":"CVE-2021-31837"},"products":["MVISION EDR"],"published":"2021-06-29","related":[],"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":"An authenticated administrator can execute arbitrary commands on the EDR client via PowerShell, requiring an upgrade to mitigate.","url":"https://insights.sbomify.com/CVE-2021-31838/"}
