中文标题:
Cisco IOS XE 资源管理错误漏洞
英文标题:
Cisco IOS XE Software Filesystem Exhaustion Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco IOS XE是美国思科（Cisco）公司的一套为其网络设备开发的操作系统。 Cisco IOS XE中的文件系统资源管理代码存在资源管理错误漏洞，该漏洞源于程序没有有效地管理底层文件系统资源。远程攻击者可利用该漏洞耗尽文件系统资源，进而造成拒绝服务。
英文描述:
A vulnerability in the filesystem resource management code of Cisco IOS XE Software could allow an unauthenticated, remote attacker to exhaust filesystem resources on an affected device and cause a denial of service (DoS) condition. The vulnerability is due to ineffective management of the underlying filesystem resources. An attacker could exploit this vulnerability by performing specific actions that result in messages being sent to specific operating system log files. A successful exploit could allow the attacker to exhaust available filesystem space on an affected device. This could cause the device to crash and reload, resulting in a DoS condition for clients whose network traffic is transiting the device. Upon reload of the device, the impacted filesystem space is cleared, and the device will return to normal operation. However, continued exploitation of this vulnerability could cause subsequent forced crashes and reloads, which could lead to an extended DoS condition.
