An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20576 in the wild and no public exploit code.\n\nAffected product: Ibm Security Verify Access. 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-2021-20576/ (Markdown: https://insights.sbomify.com/CVE-2021-20576/index.md)","id":"CVE-2021-20576","markdown":"https://insights.sbomify.com/CVE-2021-20576/index.md","name":"CVE-2021-20576","record":{"aliases":["GHSA-8pr6-wcxr-5g9c"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Security Verify Access","requires_auth":"none","summary":"A remote attacker can crash the IBM Security Verify Access application by sending a specially crafted HTTP GET request.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"application_gateway","vendor":"ibm"},{"product":"security_verify_access","vendor":"ibm"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/PR:N/S:U/C:N/AC:L/A:H/I:N/UI:N/E:U/RC:C/RL:O","version":"3.0"},"cwes":[],"description":"IBM Security Verify Access 20.07 could allow a remote attacker to send a specially crafted HTTP GET request that could cause the application to crash.","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":"Denial of service in Security Verify Access","id":"CVE-2021-20576","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ibm:security_verify_access","products":["ibm:security_verify_access"],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in Cloud Pak for Security","id":"CVE-2021-20577"},"packages":[],"prev":{"headline":"Information disclosure in Security Verify Access","id":"CVE-2021-20575"},"products":["Security Verify Access"],"published":"2021-05-31","related":[{"cvss_score":8.7,"headline":"IBM Security Verify Access information disclosure","id":"CVE-2024-28787","kev_date_added":null,"published":"2024-04-04"},{"cvss_score":5.5,"headline":"IBM Application Gateway incorrect permission assignment","id":"CVE-2024-45655","kev_date_added":null,"published":"2025-06-03"},{"cvss_score":5.4,"headline":"Security vulnerabilities have been found in IBM Application Gateway","id":"CVE-2025-36396","kev_date_added":null,"published":"2026-01-20"},{"cvss_score":5.4,"headline":"Security vulnerabilities have been found in IBM Application Gateway","id":"CVE-2025-36397","kev_date_added":null,"published":"2026-01-20"},{"cvss_score":5.4,"headline":"Cross-site scripting in Application Gateway","id":"CVE-2022-22387","kev_date_added":null,"published":"2022-09-28"},{"cvss_score":4,"headline":"Information disclosure in Security Verify Access","id":"CVE-2021-20575","kev_date_added":null,"published":"2021-05-31"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["IBM"]},"summary":"A remote attacker can crash the IBM Security Verify Access application by sending a specially crafted HTTP GET request.","url":"https://insights.sbomify.com/CVE-2021-20576/"}
