Cisco Video Surveillance 7000 Series IP Cameras 安全漏洞
英文标题:
Cisco Video Surveillance 7000 Series IP Cameras Link Layer Discovery Protocol Memory Leak Vulnerabilities
漏洞描述
中文描述:
Cisco Video Surveillance 7000 Series IP Cameras是美国思科（Cisco）公司的网络设备一款视频监控摄像头。 Cisco Video Surveillance 7000 Series IP Cameras存在安全漏洞，该漏洞源于链路层发现协议 (LLDP) 中存在多个漏洞。成功的利用可能使设备持续消耗内存，这可能导致设备崩溃并重新加载，从而导致DoS。
英文描述:
Multiple vulnerabilities in the Link Layer Discovery Protocol (LLDP) implementation for Cisco Video Surveillance 7000 Series IP Cameras could allow an unauthenticated, adjacent attacker to cause a memory leak, which could lead to a denial of service (DoS) condition on an affected device. These vulnerabilities are due to incorrect processing of certain LLDP packets at ingress time. An attacker could exploit these vulnerabilities by sending crafted LLDP packets to an affected device. A successful exploit could allow the attacker to cause the affected device to continuously consume memory, which could cause the device to crash and reload, resulting in a DoS condition. Note: LLDP is a Layer 2 protocol. To exploit these vulnerabilities, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).
