Vulnerability from fkie_nvd - Published: 2018-10-05 14:29 - Updated: 2024-11-21 03:50
Severity ?
6.8 (Medium) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H
Summary
A vulnerability in the FTP inspection engine of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability exists because the affected software fails to release spinlocks when a device is running low on system memory, if the software is configured to apply FTP inspection and an access control rule to transit traffic, and the access control rule is associated with an FTP file policy. An attacker could exploit this vulnerability by sending a high rate of transit traffic through an affected device to cause a low-memory condition on the device. A successful exploit could allow the attacker to cause a software panic on the affected device, which could cause the device to reload and result in a temporary DoS condition.

      "value": "Una vulnerabilidad en el motor de inspecci\u00f3n FTP de Cisco Firepower Threat Defense (FTD) Software podr\u00eda permitir que un atacante remoto sin autenticar haga que el dispositivo afectado se reinicie, provocando una denegaci\u00f3n de servicio (DoS) en consecuencia. La vulnerabilidad existe debido a que el software afectado no libera spinlocks cuando un dispositivo se ejecuta con poca memoria del sistema, si el software est\u00e1 configurado para aplicar una inspecci\u00f3n FTP y una regla de control de acceso para pasar tr\u00e1fico, estando esa regla de control de acceso asociada con una pol\u00edtica de archivos FTP. Un atacante podr\u00eda explotar esta vulnerabilidad enviando un gran volumen de tr\u00e1fico en tr\u00e1nsito a trav\u00e9s de un dispositivo afectado para provocar una condici\u00f3n de baja memoria en el dispositivo. Su explotaci\u00f3n con \u00e9xito podr\u00eda permitir que el atacante provoque un p\u00e1nico del software en el dispositivo afectado, lo que provocar\u00e1 que el dispositivo se recargue y desemboque en una denegaci\u00f3n de servicio (DoS) temporal."
