Cisco Clean Access多个远程安全漏洞

Cisco Clean Access CCA是一种用于自动检测、隔离、清除受恶意代码感染的设备访问网络的软件解决方案。 CCA的实现上存在两个安全漏洞，远程攻击得可能利用这些漏洞获取非授权访问或得到敏感信息。 CCA与Cisco Clean Access Manager CAM交互时，交互双方需要相同的密钥，CAM端的密钥在CAM和CAS初始化时设定，CCA实现上的漏洞使此密钥不可被更改，网络上所有相关的设备共享了相同的密钥，可能导致非授权访问。此漏洞的Cisco Bug ID为CSCsd48626，影响如下的CCA版本： CCA releases 3.6.x - 3.6.4.2 CCA...
