This vulnerability could also allow an attacker with valid user credentials, but not Administrator privileges, to view a system log file that they would not normally have access to. This vulnerability is due to a lack of rate-limiting of requests that are sent to a specific API that is related to an FMC log. An attacker could exploit this vulnerability by sending a high rate of HTTP requests to the API. A successful exploit could allow the attacker to cause a denial of service (DoS) condition due to the FMC CPU spiking to 100 percent utilization or to the device reloading. CPU utilization would return to normal if the attack traffic was stopped before an unexpected reload was triggered."}, {"lang": "es", "value": "Una vulnerabilidad en una API de registro en el software Cisco Firepower Management Center (FMC) podr\u00eda permitir que un atacante remoto no autenticado haga que el dispositivo deje de responder o desencadene una recarga inesperada. Esta vulnerabilidad tambi\u00e9n podr\u00eda permitir que un atacante con credenciales de usuario v\u00e1lidas, pero sin privilegios de administrador, vea un archivo de registro del sistema al que normalmente no tendr\u00eda acceso. Esta vulnerabilidad se debe a la falta de limitaci\u00f3n de la velocidad de las solicitudes que se env\u00edan a una API espec\u00edfica relacionada con un registro FMC. Un atacante podr\u00eda aprovechar esta vulnerabilidad enviando una alta tasa de solicitudes HTTP a la API. Un exploit exitoso podr\u00eda permitir al atacante causar una condici\u00f3n de Denegaci\u00f3n de Servicio (DoS) debido a que la CPU del FMC alcanza el 100 por ciento de utilizaci\u00f3n o a que el dispositivo se recarga. La utilizaci\u00f3n de la CPU volver\u00eda a la normalidad si el tr\u00e1fico de ataque se detuviera antes de que se desencadenara una recarga inesperada."}], "lastModified": "2024-01-25T17:15:31.683", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:cisco:firepower_management_center:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B6BF3D02-3BA0-4736-B78D-3634E3E91623", "versionEndIncluding": "6.2.3.18", "versionStartIncluding": "6.2.3"}, {"criteria": "cpe:2.3:a:cisco:firepower_management_center:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "6FBA1598-02FE-4855-8449-E2FF06EF8276", "versionEndIncluding": "6.4.0.16", "versionStartIncluding": "6.4.0"}, {"criteria": "cpe:2.3:a:cisco:firepower_management_center:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "AF3259C7-8F36-46B1-A1BA-C2F9AC165A2D", "versionEndIncluding": "6.6.7.1", "versionStartIncluding": "6.6.0"}, {"criteria": "cpe:2.3:a:cisco:firepower_management_center:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "0BE29E8B-5D64-4CF6-B8CB-A38E991A9BB9", "versionEndIncluding": "7.0.5", "versionStartIncluding": "7.0.0"}, {"criteria": "cpe:2.3:a:cisco:firepower_management_center:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "749D90E8-9009-4F05-8C5E-2521A9BC7D32", "versionEndIncluding": "7.1.0.3", "versionStartIncluding": "7.1.0"}, {"criteria": "cpe:2.3:a:cisco:firepower_management_center:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D44E33FB-20A2-448B-A901-3BD383E45F2B", "versionEndIncluding": "7.2.3.1", "versionStartIncluding": "7.2.0"}, {"criteria": "cpe:2.3:a:cisco:firepower_management_center:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E355BD8E-18E7-4405-8F32-0A191DCE0774", "versionEndIncluding": "7.3.1.1", "versionStartIncluding": "7.3.0"}], "operator": "OR"}]}], "sourceIdentifier": "ykramarz@cisco.com"}
