An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-31848 and fix it if it is affected.\n\nWhat it is: CVE-2021-31848 is a high-severity cross-site scripting vulnerability in McAfee Data Loss Prevention (DLP) ePO extension, published on 1 Nov 2021. 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-2021-31848 in the wild and no public exploit code.\n\nAffected product: McAfee Data Loss Prevention (DLP) ePO extension. 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-2021-31848/ (Markdown: https://insights.sbomify.com/CVE-2021-31848/index.md)","id":"CVE-2021-31848","markdown":"https://insights.sbomify.com/CVE-2021-31848/index.md","name":"CVE-2021-31848","record":{"aliases":["GHSA-h28h-cmg9-rmpc"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"McAfee DLP ePO extension","requires_auth":"high_privilege","summary":"Remote attackers can hijack administrator sessions via crafted links in the DLP ePO extension case management interface.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"data_loss_prevention_endpoint","vendor":"mcafee"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross site scripting (XSS) vulnerability in McAfee Data Loss Prevention (DLP) ePO extension prior to 11.7.100 allows a remote attacker to highjack an active DLP ePO administrator session by convincing the logged in administrator to click on a carefully crafted link in the case management part of the DLP ePO extension.","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":"Data Loss Prevention (DLP) ePO extension - Cross site scripting (XSS)","id":"CVE-2021-31848","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Data Loss Prevention (DLP) ePO extension - SQL injection","id":"CVE-2021-31849"},"packages":[],"prev":{"headline":"Improper privilege management in repair process of MA for Windows","id":"CVE-2021-31847"},"products":["Data Loss Prevention (DLP) ePO extension"],"published":"2021-11-01","related":[{"cvss_score":8.4,"headline":"Data Loss Prevention (DLP) ePO extension - SQL injection","id":"CVE-2021-31849","kev_date_added":null,"published":"2021-11-01"},{"cvss_score":8.2,"headline":"Local Privilege Escalation in McAfee DLP Endpoint for Windows","id":"CVE-2021-31844","kev_date_added":null,"published":"2021-09-17"},{"cvss_score":7.8,"headline":"Privilege escalation in McAfee DLP Endpoint for Windows","id":"CVE-2021-23887","kev_date_added":null,"published":"2021-04-15"},{"cvss_score":7.8,"headline":"Privilege escalation in Data Loss Prevention Endpoint (DLPe)","id":"CVE-2016-8012","kev_date_added":null,"published":"2017-03-14"},{"cvss_score":7.5,"headline":"DLP Endpoint log file redirection to arbitrary locations","id":"CVE-2019-3622","kev_date_added":null,"published":"2019-07-24"},{"cvss_score":7.2,"headline":"Security feature bypass in Data Loss Prevention (DLP) for Windows","id":"CVE-2018-6683","kev_date_added":null,"published":"2018-07-23"}],"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"]},"summary":"Remote attackers can hijack administrator sessions via crafted links in the DLP ePO extension case management interface.","url":"https://insights.sbomify.com/CVE-2021-31848/"}
