An attacker could exploit this vulnerability by connecting to an AP on an affected device as a wireless client and sending a high rate of traffic over an extended period of time. A successful exploit could allow the attacker to cause the Datagram TLS (DTLS) session to tear down and reset, causing a denial of service (DoS) condition.","publishedAt":"2023-09-27T17:25:00.473Z","updatedAt":"2024-08-02T09:05:34.976Z","severity":{"score":5.8,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L","source":"cisco"},"assigner":"cisco","products":["Cisco Cisco Aironet Access Point Software","Cisco Cisco Aironet Access Point Software (IOS XE Controller)"],"affected":[{"vendor":"Cisco","product":"Cisco Aironet Access Point Software","versions":[{"version":"8.10.170.0","status":"affected"}]},{"vendor":"Cisco","product":"Cisco Aironet Access Point Software (IOS XE Controller)","versions":[{"version":"16.10.1e","status":"affected"},{"version":"16.10.1","status":"affected"},{"version":"17.1.1t","status":"affected"},{"version":"17.1.1s","status":"affected"},{"version":"17.1.1","status":"affected"},{"version":"16.11.1a","status":"affected"},{"version":"16.11.1","status":"affected"},{"version":"16.11.1c","status":"affected"},{"version":"16.11.1b","status":"affected"},{"version":"16.12.1s","status":"affected"},{"version":"16.12.4","status":"affected"},{"version":"16.12.1","status":"affected"},{"version":"16.12.2s","status":"affected"},{"version":"16.12.1t","status":"affected"},{"version":"16.12.4a","status":"affected"},{"version":"16.12.5","status":"affected"},{"version":"16.12.3","status":"affected"},{"version":"16.12.6","status":"affected"},{"version":"16.12.8","status":"affected"},{"version":"16.12.7","status":"affected"},{"version":"16.12.6a","status":"affected"},{"version":"17.3.1","status":"affected"},{"version":"17.3.2a","status":"affected"},{"version":"17.3.3","status":"affected"},{"version":"17.3.2","status":"affected"},{"version":"17.3.4c","status":"affected"},{"version":"17.3.5a","status":"affected"},{"version":"17.3.6","status":"affected"},{"version":"17.2.1","status":"affected"},{"version":"17.2.1a","status":"affected"},{"version":"17.2.3","status":"affected"},{"version":"17.2.2","status":"affected"},{"version":"17.5.1","status":"affected"},{"version":"17.4.1","status":"affected"},{"version":"17.4.2","status":"affected"},{"version":"17.6.1","status":"affected"},{"version":"17.6.2","status":"affected"},{"version":"17.6.3","status":"affected"},{"version":"17.6.4","status":"affected"},{"version":"17.6.5","status":"affected"},{"version":"17.7.1","status":"affected"},{"version":"17.8.1","status":"affected"}]}],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-click-ap-dos-wdcXkvnQ"],"weaknesses":["CWE-400"],"ingestedAt":"2026-10-29T20:05:36.141Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/20xxx/CVE-2023-20176.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-20176","state":"PUBLISHED","datePublished":"2023-09-27T17:25:00.473Z","dateUpdated":"2024-08-02T09:05:34.976Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2022-10-27T18:47:50.363Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"A vulnerability in the networking component of Cisco access point (AP) software could allow an unauthenticated, remote attacker to cause a temporary disruption of service.\r\n\r This vulnerability is due to overuse of AP resources.
