An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-21490 in the wild and no public exploit code.\n\nAffected product: Sap Netweaver Application Server Abap. 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-2021-21490/ (Markdown: https://insights.sbomify.com/CVE-2021-21490/index.md)","id":"CVE-2021-21490","markdown":"https://insights.sbomify.com/CVE-2021-21490/index.md","name":"CVE-2021-21490","record":{"aliases":["GHSA-c8cw-5vg3-hjw3"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"SAP NetWeaver Web Survey","requires_auth":"none","summary":"Reflected XSS in SAP NetWeaver Web Survey allows attackers to steal session data and impersonate users to access sensitive information.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sap","cpe":[{"product":"netweaver_application_server_abap","vendor":"sap"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/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 AS for ABAP (Web Survey), versions - 700, 702, 710, 711, 730, 731, 750, 750, 752, 75A, 75F, does not sufficiently encode input and output parameters which results in reflected cross site scripting vulnerability, through which a malicious user can access data relating to the current session and use it to impersonate a user and access all information with the same rights as the target user.","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":"Cross-site scripting in SAP NetWeaver AS for ABAP (Web Survey)","id":"CVE-2021-21490","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"sap:netweaver_application_server_abap","products":["sap:netweaver_application_server_abap"],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Open redirect in SAP NetWeaver Application Server Java (Applications based on Web Dynpro Java)","id":"CVE-2021-21491"},"packages":[],"prev":{"headline":"Cross-site scripting in SAP NetWeaver Enterprise Portal","id":"CVE-2021-21489"},"products":["SAP NetWeaver AS for ABAP (Web Survey)"],"published":"2021-06-09","related":[{"cvss_score":9.9,"headline":"Code Injection vulnerability in SAP CRM and SAP S/4HANA (Scripting Editor)","id":"CVE-2026-0488","kev_date_added":null,"published":"2026-02-10"},{"cvss_score":9.8,"headline":"Code injection in SAP NetWeaver Application Server for ABAP (SAP Cloud Print Manager and SAPSprint)","id":"CVE-2021-40499","kev_date_added":null,"published":"2021-10-12"},{"cvss_score":9.6,"headline":"Directory Traversal vulnerability in SAP NetWeaver AS for ABAP and ABAP Platform","id":"CVE-2023-27269","kev_date_added":null,"published":"2023-03-14"},{"cvss_score":9.6,"headline":"Directory Traversal vulnerability in SAP NetWeaver AS for ABAP and ABAP Platform","id":"CVE-2023-27500","kev_date_added":null,"published":"2023-03-14"},{"cvss_score":9,"headline":"Capture-replay vulnerability in SAP NetWeaver AS for ABAP and ABAP Platform","id":"CVE-2023-0014","kev_date_added":null,"published":"2023-01-10"},{"cvss_score":8.8,"headline":"Missing authorization in SAP NetWeaver Application Server for ABAP and ABAP Platform","id":"CVE-2022-29611","kev_date_added":null,"published":"2022-05-11"},{"cvss_score":8.8,"headline":"Missing authorization in ABAP Platform(SAP Basis)","id":"CVE-2019-0257","kev_date_added":null,"published":"2019-02-15"}],"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":["SAP SE"]},"summary":"Reflected XSS in SAP NetWeaver Web Survey allows attackers to steal session data and impersonate users to access sensitive information.","url":"https://insights.sbomify.com/CVE-2021-21490/"}
