Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20464 in the wild and no public exploit code.\n\nAffected product: Ibm Cognos Analytics. 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-2021-20464/ (Markdown: https://insights.sbomify.com/CVE-2021-20464/index.md)","id":"CVE-2021-20464","markdown":"https://insights.sbomify.com/CVE-2021-20464/index.md","name":"CVE-2021-20464","record":{"aliases":["GHSA-6cvg-3r48-6prg"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Cognos Analytics","requires_auth":"low_privilege","summary":"A malicious authenticated user can cause a denial of service in IBM Cognos Analytics via an XML Bomb attack.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"cognos_analytics","vendor":"ibm"},{"product":"oncommand_insight","vendor":"netapp"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/C:N/AC:L/S:U/A:H/UI:N/AV:N/PR:L/I:N/E:U/RC:C/RL:O","version":"3.0"},"cwes":[{"id":"CWE-776","name":"Improper Restriction of Recursive Entity References in DTDs"}],"description":"IBM Cognos Analytics PowerPlay (IBM Cognos Analytics 11.1.7, 11.2.0, and 11.1.7) could be vulnerable to an XML Bomb attack by a malicious authenticated user.
