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-2020-7261 in the wild and no public exploit code.\n\nAffected product: McAfee Endpoint Security (ENS). 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-2020-7261/ (Markdown: https://insights.sbomify.com/CVE-2020-7261/index.md)","id":"CVE-2020-7261","markdown":"https://insights.sbomify.com/CVE-2020-7261/index.md","name":"CVE-2020-7261","record":{"aliases":["GHSA-x222-6c25-wc8w"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Endpoint Security","requires_auth":"low_privilege","summary":"Local attackers can exploit a buffer overflow in McAfee ENS to disable endpoint security protections, bypassing AMSI and other defenses.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"endpoint_security","vendor":"mcafee"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Buffer Overflow via Environment Variables vulnerability in AMSI component in McAfee Endpoint Security (ENS) Prior to 10.7.0 February 2020 Update allows local users to disable Endpoint Security via a carefully crafted user input.","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":"Buffer overwrite in ENS allowed to bypass AMSI protection","id":"CVE-2020-7261","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Improper Access Control vulnerability in ATD","id":"CVE-2020-7262"},"packages":[],"prev":{"headline":"MACC installer DLL side loading","id":"CVE-2020-7260"},"products":["McAfee Endpoint Security (ENS)"],"published":"2020-04-15","related":[{"cvss_score":8.8,"headline":"Improper Access Control Vulnerability in ENS for Windows","id":"CVE-2020-7319","kev_date_added":null,"published":"2020-09-09"},{"cvss_score":8.8,"headline":"Privilege Escalation vulnerability through symbolic links in ENS for Windows","id":"CVE-2020-7264","kev_date_added":null,"published":"2020-05-08"},{"cvss_score":8.8,"headline":"Privilege Escalation vulnerability through symbolic links in ENSM","id":"CVE-2020-7265","kev_date_added":null,"published":"2020-05-08"},{"cvss_score":8.6,"headline":"McAfee Endpoint Security updates fix a privilege escalation vulnerability","id":"CVE-2019-3582","kev_date_added":null,"published":"2019-02-28"},{"cvss_score":8.4,"headline":"Privilege Escalation vulnerability through Symbolic links in ENS","id":"CVE-2020-7257","kev_date_added":null,"published":"2020-04-15"},{"cvss_score":8.2,"headline":"Improper Access Control in the ENS installer","id":"CVE-2021-23882","kev_date_added":null,"published":"2021-02-10"},{"cvss_score":8.2,"headline":"ENS symbolic link log file manipulation vulnerability","id":"CVE-2020-7250","kev_date_added":null,"published":"2020-04-15"}],"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":"2024-09-16","vendors":["McAfee LLC"]},"summary":"Local attackers can exploit a buffer overflow in McAfee ENS to disable endpoint security protections, bypassing AMSI and other defenses.","url":"https://insights.sbomify.com/CVE-2020-7261/"}
