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-2021-21492 in the wild and no public exploit code.\n\nAffected product: Sap Netweaver Application Server Java. 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-2021-21492/ (Markdown: https://insights.sbomify.com/CVE-2021-21492/index.md)","id":"CVE-2021-21492","markdown":"https://insights.sbomify.com/CVE-2021-21492/index.md","name":"CVE-2021-21492","record":{"aliases":["GHSA-p6c6-6r9j-859q"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"SAP NetWeaver AS Java","requires_auth":"none","summary":"Attackers can spoof content via unvalidated logon groups in URLs when directory listing is enabled, potentially misleading users or exposing information.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sap","cpe":[{"product":"netweaver_application_server_java","vendor":"sap"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"SAP NetWeaver Application Server Java(HTTP Service), versions - 7.10, 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, does not sufficiently validate logon group in URLs, resulting in a content spoofing vulnerability when directory listing is enabled.","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":"Other in SAP NetWeaver AS for JAVA (HTTP Service)","id":"CVE-2021-21492","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"sap:netweaver_application_server_java","products":["sap:netweaver_application_server_java"],"type":"other","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Denial of service in SAP 3D Visual Enterprise Viewer","id":"CVE-2021-21493"},"packages":[],"prev":{"headline":"Open redirect in SAP NetWeaver Application Server Java (Applications based on Web Dynpro Java)","id":"CVE-2021-21491"},"products":["SAP NetWeaver AS for JAVA (HTTP Service)"],"published":"2021-04-13","related":[{"cvss_score":10,"headline":"SAP NetWeaver Missing Authentication for Critical Function","id":"CVE-2020-6287","kev_date_added":"2021-11-03","published":"2020-07-14"},{"cvss_score":10,"headline":"SAP NetWeaver Remote Code Execution","id":"CVE-2010-5326","kev_date_added":"2021-11-03","published":"2016-05-13"},{"cvss_score":9.8,"headline":"SAP NetWeaver SQL Injection","id":"CVE-2016-2386","kev_date_added":"2022-06-09","published":"2016-02-16"},{"cvss_score":7.5,"headline":"SAP NetWeaver Directory Traversal","id":"CVE-2017-12637","kev_date_added":"2025-03-19","published":"2017-08-07"},{"cvss_score":7.5,"headline":"SAP NetWeaver Directory Traversal","id":"CVE-2016-3976","kev_date_added":"2021-11-03","published":"2016-04-07"},{"cvss_score":6.5,"headline":"SAP NetWeaver XML External Entity (XXE)","id":"CVE-2016-9563","kev_date_added":"2021-11-03","published":"2016-11-23"},{"cvss_score":5.3,"headline":"SAP NetWeaver Information Disclosure","id":"CVE-2016-2388","kev_date_added":"2022-06-09","published":"2016-02-16"}],"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":"Attackers can spoof content via unvalidated logon groups in URLs when directory listing is enabled, potentially misleading users or exposing information.","url":"https://insights.sbomify.com/CVE-2021-21492/"}
