Cisco Wireless LAN Controller Software 输入验证错误漏洞
英文标题:
Cisco Wireless LAN Controller Secure Shell Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco Wireless LAN Controller(WLC)Software是美国思科(Cisco)公司的一套用于配置和管理WLC(无线局域网控制器)的软件。 Cisco WLC Software 8.5.140.0及之前版本中的Secure Shell会话管理存在输入验证错误漏洞,该漏洞源于当SSH连接断开时,程序没有正确删除SSH会话。远程攻击者可通过重复打开SSH连接利用该漏洞造成拒绝服务。
英文描述:
A vulnerability in the Secure Shell (SSH) session management for Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability exists because the SSH process is not properly deleted when an SSH connection to the device is disconnected. An attacker could exploit this vulnerability by repeatedly opening SSH connections to an affected device. A successful exploit could allow the attacker to exhaust system resources by initiating multiple SSH connections to the device that are not effectively terminated, which could result in a DoS condition.
