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-2021-21476 in the wild and no public exploit code.\n\nAffected product: SAP UI5. 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-2021-21476/ (Markdown: https://insights.sbomify.com/CVE-2021-21476/index.md)","id":"CVE-2021-21476","markdown":"https://insights.sbomify.com/CVE-2021-21476/index.md","name":"CVE-2021-21476","record":{"aliases":["GHSA-8279-2hh7-mpv3"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"SAP UI5 library","requires_auth":"none","summary":"An unauthenticated attacker can redirect users to malicious sites via reverse tabnabbing in SAP UI5, requiring an upgrade to mitigate.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sap","cpe":[{"product":"ui5","vendor":"sap"}],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"SAP UI5 versions before 1.38.49, 1.52.49, 1.60.34, 1.71.31, 1.78.18, 1.84.5, 1.85.4, 1.86.1 allows an unauthenticated attacker to redirect users to a malicious site due to Reverse Tabnabbing vulnerabilities.","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":"Open redirect in SAP UI5","id":"CVE-2021-21476","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"open_redirect","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Code injection in SAP Commerce","id":"CVE-2021-21477"},"packages":[],"prev":{"headline":"Path traversal in SAP NetWeaver Master Data Management Server","id":"CVE-2021-21475"},"products":["SAP UI5"],"published":"2021-02-09","related":[],"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":"An unauthenticated attacker can redirect users to malicious sites via reverse tabnabbing in SAP UI5, requiring an upgrade to mitigate.","url":"https://insights.sbomify.com/CVE-2021-21476/"}
