An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-23881 in the wild and no public exploit code.\n\nAffected product: McAfee LLC Endpoint Security (ENS) for Windows. 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-2021-23881/ (Markdown: https://insights.sbomify.com/CVE-2021-23881/index.md)","id":"CVE-2021-23881","markdown":"https://insights.sbomify.com/CVE-2021-23881/index.md","name":"CVE-2021-23881","record":{"aliases":["GHSA-ffrc-37fw-2f8x"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Endpoint Security","requires_auth":"high_privilege","summary":"An administrator can inject scripts into policy events that execute in a browser block page when triggered by a local user.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"endpoint_security","vendor":"mcafee"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A stored cross site scripting vulnerability in ePO extension of McAfee Endpoint Security (ENS) prior to 10.7.0 February 2021 Update allows an ENS ePO administrator to add a script to a policy event which will trigger the script to be run through a browser block page when a local non-administrator user triggers the policy.","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":"Stored Cross Site Scripting in ENS","id":"CVE-2021-23881","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Improper Access Control in the ENS installer","id":"CVE-2021-23882"},"packages":[],"prev":{"headline":"Improper Access Control in the ENS installer","id":"CVE-2021-23880"},"products":["Endpoint Security (ENS) for Windows"],"published":"2021-02-10","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":"2024-09-17","vendors":["McAfee LLC"]},"summary":"An administrator can inject scripts into policy events that execute in a browser block page when triggered by a local user.","url":"https://insights.sbomify.com/CVE-2021-23881/"}
