漏洞描述
中文描述:
Cisco Catalyst Switches等都是美国思科（Cisco）公司的交换机产品。Cisco IOS和IOS XE都是运行于其中的操作系统。 多款Cisco产品中的IOS和IOS XE Software的Cluster Management Protocol (CMP)处理代码存在远程代码执行漏洞。远程攻击者可利用该漏洞造成受影响设备重载，或以提升的权限执行代码。以下设备受到影响：Cisco Catalyst switches；Embedded Service 2020 switches；Enhanced Layer 2 EtherSwitch Service Module；Enhanced Layer 2/3 EtherSwitch Service Module；Gigabit Ethernet Switch Module (CGESM) for HP；IE Industrial Ethernet switches；ME 4924-10GE switch；RF Gateway 10；SM-X Layer 2/3 EtherSwitch Service Module。
英文描述:
A vulnerability in the Cisco Cluster Management Protocol (CMP) processing code in Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a reload of an affected device or remotely execute code with elevated privileges. The Cluster Management Protocol utilizes Telnet internally as a signaling and command protocol between cluster members. The vulnerability is due to the combination of two factors: (1) the failure to restrict the use of CMP-specific Telnet options only to internal, local communications between cluster members and instead accept and process such options over any Telnet connection to an affected device; and (2) the incorrect processing of malformed CMP-specific Telnet options. An attacker could exploit this vulnerability by sending malformed CMP-specific Telnet options while establishing a Telnet session with an affected Cisco device configured to accept Telnet connections. An exploit could allow an attacker to execute arbitrary code and obtain full control of the device or cause a reload of the affected device. This affects Catalyst switches, Embedded Service 2020 switches, Enhanced Layer 2 EtherSwitch Service Module, Enhanced Layer 2/3 EtherSwitch Service Module, Gigabit Ethernet Switch Module (CGESM) for HP, IE Industrial Ethernet switches, ME 4924-10GE switch, RF Gateway 10, and SM-X Layer 2/3 EtherSwitch Service Module. Cisco Bug IDs: CSCvd48893.
