Cisco Clean Access CCA 3.6.x through 3.6.4.2 and 4.0.x through 4.0.3.2 does not properly configure or allow modification of a shared secret authentication key, which causes all devices to have the same shared sercet and allows remote attackers to gain unauthorized access...

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...
