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."},{"lang":"es","value":"Varios productos de Cisco se ven afectados por una vulnerabilidad en la función de filtrado de velocidad del motor de detección Snort que podría permitir que un atacante remoto no autenticado eluda un filtro de limitación de velocidad configurado. Esta vulnerabilidad se debe a una comparación incorrecta del recuento de conexiones. Un atacante podría aprovechar esta vulnerabilidad enviando tráfico a través de un dispositivo afectado a una velocidad que supere un filtro de velocidad configurado. Una explotación exitosa podría permitir que el atacante eluda con éxito el filtro de velocidad. Esto podría permitir que el tráfico no deseado ingrese a la red protegida por el dispositivo afectado."}],"metrics":{"cvssMetricV31":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L","baseScore":5.8,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":3.9,"impactScore":1.4},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N","baseScore":8.6,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":4.0}]},"weaknesses":[{"source":"psirt@cisco.com","type":"Secondary","description":[{"lang":"en","value":"CWE-1025"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:snort:*:*:*:*:*:*:*:*","versionStartIncluding":"3.0.0.0","versionEndExcluding":"3.1.74.0","matchCriteriaId":"ABB4268E-57E8-4254-96DB-98A4CB48C921"}]}]},{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:firepower_threat_defense_software:*:*:*:*:*:*:*:*","versionEndExcluding":"7.0.6.2","matchCriteriaId":"D91E6016-526F-43B6-B1AA-BAA6C216CEFA"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:firepower_threat_defense_software:*:*:*:*:*:*:*:*","versionStartIncluding":"7.2.0","versionEndExcluding":"7.2.6","matchCriteriaId":"E10E0135-652B-44E0-9C53-8F03DC4D7A06"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:firepower_threat_defense_software:*:*:*:*:*:*:*:*","versionStartIncluding":"7.4.0","versionEndExcluding":"7.4.2","matchCriteriaId":"C40A9738-3503-4F8B-88CD-5DEA46DB3CD8"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:firepower_threat_defense_software:7.1.0:*:*:*:*:*:*:*","matchCriteriaId":"B07AA16A-6DE0-4226-8A44-CDA8E26830D3"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:firepower_threat_defense_software:7.3.0:*:*:*:*:*:*:*","matchCriteriaId":"8AF82E95-C8D3-402B-BC97-29EA1771D5EA"}]}]}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-snort-rf-bypass-OY8f3pnM","source":"psirt@cisco.com","tags":["Vendor Advisory"]}]}}]}
