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-2021-4038 in the wild and no public exploit code.\n\nAffected product: McAfee,LLC McAfee Network Security Manager (NSM). 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-2021-4038/ (Markdown: https://insights.sbomify.com/CVE-2021-4038/index.md)","id":"CVE-2021-4038","markdown":"https://insights.sbomify.com/CVE-2021-4038/index.md","name":"CVE-2021-4038","record":{"aliases":["GHSA-jrmj-jm9w-qhxm"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Network Security Manager","requires_auth":"high_privilege","summary":"Remote authenticated administrators can inject malicious scripts into the McAfee NSM interface via unsanitized custom rules, potentially compromising the management console.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"network_security_manager","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":"Cross Site Scripting (XSS) vulnerability in McAfee Network Security Manager (NSM) prior to 10.1 Minor 7 allows a remote authenticated administrator to embed a XSS in the administrator interface via specially crafted custom rules containing HTML.
