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-2022-20937 in the wild and no public exploit code.\n\nAffected product: Cisco Identity Services Engine. 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-2022-20937/ (Markdown: https://insights.sbomify.com/CVE-2022-20937/index.md)","id":"CVE-2022-20937","markdown":"https://insights.sbomify.com/CVE-2022-20937/index.md","name":"CVE-2022-20937","record":{"aliases":["GHSA-pmp2-f627-c94j"],"analysis":{"component_type":"server_software","fix_type":"workaround","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Identity Services Engine","requires_auth":"none","summary":"An unauthenticated remote attacker can cause significant delays in RADIUS authentications by exploiting insufficient resource management in Cisco ISE.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"identity_services_engine","vendor":"cisco"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"},{"id":"CWE-410","name":"Insufficient Resource Pool"}],"description":"A vulnerability in a feature that monitors RADIUS requests on Cisco Identity Services Engine (ISE) Software could allow an unauthenticated, remote attacker to negatively affect the performance of an affected device.\r\n\r This vulnerability is due to insufficient management of system resources.
