{"id":"CVE-2024-20342","state":"PUBLISHED","title":"Cisco Firepower Threat Defense Software Rate Filter Bypass Vulnerability","description":"Multiple Cisco products are affected by a vulnerability in the rate filtering feature of the Snort detection engine that could allow an unauthenticated, remote attacker to bypass a configured rate limiting filter. \r\n\r\nThis vulnerability is due to an incorrect connection count comparison. An attacker could exploit this vulnerability by sending traffic through an affected device at a rate that exceeds a configured rate filter. A successful exploit could allow the attacker to successfully bypass the rate filter. This could allow unintended traffic to enter the network protected by the affected device.","publishedAt":"2024-10-23T17:09:27.934Z","updatedAt":"2025-01-13T17:46:29.797Z","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 Firepower Threat Defense Software"],"affected":[{"vendor":"Cisco","product":"Cisco Firepower Threat Defense Software","defaultStatus":"unknown","versions":[{"version":"7.0.0","status":"affected"},{"version":"7.0.0.1","status":"affected"},{"version":"7.0.1","status":"affected"},{"version":"7.1.0","status":"affected"},{"version":"7.0.1.1","status":"affected"},{"version":"7.1.0.1","status":"affected"},{"version":"7.0.2","status":"affected"},{"version":"7.2.0","status":"affected"},{"version":"7.0.2.1","status":"affected"},{"version":"7.0.3","status":"affected"},{"version":"7.1.0.2","status":"affected"},{"version":"7.2.0.1","status":"affected"},{"version":"7.0.4","status":"affected"},{"version":"7.2.1","status":"affected"},{"version":"7.0.5","status":"affected"},{"version":"7.3.0","status":"affected"},{"version":"7.2.2","status":"affected"},{"version":"7.2.3","status":"affected"},{"version":"7.3.1","status":"affected"},{"version":"7.1.0.3","status":"affected"},{"version":"7.2.4","status":"affected"},{"version":"7.0.6","status":"affected"},{"version":"7.2.5","status":"affected"},{"version":"7.2.4.1","status":"affected"},{"version":"7.3.1.1","status":"affected"},{"version":"7.4.0","status":"affected"},{"version":"7.0.6.1","status":"affected"},{"version":"7.2.5.1","status":"affected"},{"version":"7.4.1","status":"affected"},{"version":"7.4.1.1","status":"affected"},{"version":"7.2.5.2","status":"affected"},{"version":"7.3.1.2","status":"affected"}]}],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-snort-rf-bypass-OY8f3pnM"],"weaknesses":["CWE-1025"],"ingestedAt":"2026-10-29T20:06:59.846Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/20xxx/CVE-2024-20342.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2024-20342","state":"PUBLISHED","datePublished":"2024-10-23T17:09:27.934Z","dateUpdated":"2025-01-13T17:46:29.797Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2023-11-08T15:08:07.643Z"},"containers":{"cna":{"title":"Cisco Firepower Threat Defense Software Rate Filter Bypass Vulnerability","descriptions":[{"lang":"en","value":"Multiple Cisco products are affected by a vulnerability in the rate filtering feature of the Snort detection engine that could allow an unauthenticated, remote attacker to bypass a configured rate limiting filter. \r\n\r\nThis vulnerability is due to an incorrect connection count comparison.
