漏洞描述
中文描述:
Cisco Wireless LAN Controller(WLC)是美国思科(Cisco)公司的一款无线局域网控制器产品。该产品在无线局域网中提供安全策略、入侵检测等功能。Simple Network Management Protocol(SNMP)是其中的一个用于网络设备管理信息交换的简单网络管理子系统。 Cisco WLC中的SNMP子系统存在拒绝服务漏洞,该漏洞设备上出现内存泄露。远程攻击者可利用该漏洞造成拒绝服务(设备重启)。
英文描述:
A vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco Wireless LAN Controllers could allow an authenticated, remote attacker to cause an affected device to restart, resulting in a denial of service (DoS) condition. The vulnerability is due to a memory leak that occurs on an affected device after the device fails to deallocate a buffer that is used when certain MIBs are polled. An attacker who knows the SNMP Version 2 SNMP Read string or has valid SNMP Version 3 credentials for an affected device could repeatedly poll the affected MIB object IDs (OIDs) and consume available memory on the device. When memory is sufficiently depleted on the device, the device will restart, resulting in a DoS condition. Cisco Bug IDs: CSCvc71674.
