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-2021-21489 in the wild and no public exploit code.\n\nAffected product: SAP NetWeaver Enterprise Portal. 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-2021-21489/ (Markdown: https://insights.sbomify.com/CVE-2021-21489/index.md)","id":"CVE-2021-21489","markdown":"https://insights.sbomify.com/CVE-2021-21489/index.md","name":"CVE-2021-21489","record":{"aliases":["GHSA-7chv-w23j-556x"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"SAP NetWeaver Portal","requires_auth":"high_privilege","summary":"An attacker with admin privileges can inject malicious scripts into the SAP NetWeaver Enterprise Portal, compromising user data confidentiality and integrity.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sap","cpe":[{"product":"netweaver_enterprise_portal","vendor":"sap"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"SAP NetWeaver Enterprise Portal versions - 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, does not sufficiently encode user related data, resulting in Stored Cross-Site Scripting (XSS) vulnerability.
