漏洞描述
中文描述:
Cisco Prime Access Registrar和Prime Access Registrar Jumpstar都是美国思科(Cisco)公司的Cisco Prime访问注册器。 Cisco Prime Access Registrar和Prime Access Registrar Jumpstart 7.3.0.4之前版本和8.0.1.1版本中的TCP连接管理存在资源管理错误漏洞,该漏洞源于程序没有正确的处理发送到监听端口的TCP SYN数据包。远程攻击者可通过向程序发送一连串特制的TCP SYN数据包利用该漏洞造成拒绝服务(应用程序意外重启)。
英文描述:
A vulnerability in TCP connection management in Cisco Prime Access Registrar could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition when the application unexpectedly restarts. The vulnerability is due to incorrect handling of incoming TCP SYN packets to specific listening ports. The improper handling of the TCP SYN packets could cause a system file description to be allocated and not freed. An attacker could exploit this vulnerability by sending a crafted stream of TCP SYN packets to the application. A successful exploit could allow the attacker to cause the application to eventually restart if a file description cannot be obtained.
