Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-23885 in the wild and no public exploit code.\n\nAffected product: McAfee,LLC McAfee Web Gateway (MWG). 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-2021-23885/ (Markdown: https://insights.sbomify.com/CVE-2021-23885/index.md)","id":"CVE-2021-23885","markdown":"https://insights.sbomify.com/CVE-2021-23885/index.md","name":"CVE-2021-23885","record":{"aliases":["GHSA-286x-xfxm-75r6"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Web Gateway","requires_auth":"low_privilege","summary":"Authenticated users can escalate privileges and execute commands on McAfee Web Gateway via improper input neutralization in the troubleshooting interface.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"web_gateway","vendor":"mcafee"}],"cvss":{"score":9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"Privilege escalation vulnerability in McAfee Web Gateway (MWG) prior to 9.2.8 allows an authenticated user to gain elevated privileges through the User Interface and execute commands on the appliance via incorrect improper neutralization of user input in the troubleshooting page.","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":"Privilege escalation vulnerability in McAfee Web Gateway (MWG) UI","id":"CVE-2021-23885","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":"Local Denial of Service in McAfee DLP Endpoint for Windows","id":"CVE-2021-23886"},"packages":[],"prev":{"headline":"Clear text exposure of password in McAfee CSR ePO extension","id":"CVE-2021-23884"},"products":["McAfee Web Gateway (MWG)"],"published":"2021-02-17","related":[{"cvss_score":9,"headline":"Web Gateway (MWG) - Privilege Escalation vulnerability","id":"CVE-2020-7293","kev_date_added":null,"published":"2020-09-15"},{"cvss_score":8.1,"headline":"Web Gateway (MWG) - Reflected Cross Site Scripting vulnerability","id":"CVE-2019-3638","kev_date_added":null,"published":"2019-09-12"},{"cvss_score":7.1,"headline":"MWG UI: Cross-Frame Scripting vulnerability","id":"CVE-2019-3639","kev_date_added":null,"published":"2019-08-14"},{"cvss_score":6.1,"headline":"SWG URL redirection vulnerability","id":"CVE-2022-1254","kev_date_added":null,"published":"2022-04-20"},{"cvss_score":5.7,"headline":"Web Gateway (MWG) - Privilege Escalation vulnerability","id":"CVE-2020-7296","kev_date_added":null,"published":"2020-09-15"},{"cvss_score":5.7,"headline":"Web Gateway (MWG) - Privilege Escalation vulnerability","id":"CVE-2020-7297","kev_date_added":null,"published":"2020-09-15"}],"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":"2024-08-03","vendors":["McAfee,LLC"]},"summary":"Authenticated users can escalate privileges and execute commands on McAfee Web Gateway via improper input neutralization in the troubleshooting interface.","url":"https://insights.sbomify.com/CVE-2021-23885/"}
