漏洞描述
中文描述:

Cisco NX-OS Software和Cisco FXOS Software都是美国思科（Cisco）公司的产品。Cisco NX-OS Software是一套交换机使用的数据中心级操作系统软件。Cisco FXOS Software是一套运行在思科安全设备中的防火墙软件。 Cisco FXOS Software和Cisco NX-OS Software中的轻量目录访问协议(LDAP)功能的实现存在输入验证漏洞，该漏洞源于程序错误地解析了LDAP数据包。远程攻击者可通过发送由基本编码规则(BER)构建的LDAP数据包利用该漏洞重新加载受影响设备，造成拒绝服务。以下产品受到影响：Cisco Firepower 4100 Series Next-Generation Firewalls；Firepower 9300 Security Appliance；MDS 9000 Series Multilayer Switches；Nexus 3000 Series Switches；Nexus 3500 Platform Switches；Nexus 7000 Series Switches；Nexus 7700 Series Switches；Nexus 9000 Series Switches in standalone NX-OS mode；UCS 6200 Series Fabric Interconnects；UCS 6300 Series Fabric Interconnects。

英文描述:

Multiple vulnerabilities in the implementation of the Lightweight Directory Access Protocol (LDAP) feature in Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerabilities are due to the improper parsing of LDAP packets by an affected device. An attacker could exploit these vulnerabilities by sending an LDAP packet crafted using Basic Encoding Rules (BER) to an affected device. The LDAP packet must have a source IP address of an LDAP server configured on the targeted device. A successful exploit could cause the affected device to reload, resulting in a DoS condition. Firepower 4100 Series Next-Generation Firewalls are affected in versions prior to 2.0.1.201, 2.2.2.54, and 2.3.1.75. Firepower 9300 Security Appliances are affected in versions prior to 2.0.1.201, 2.2.2.54 and 2.3.1.75. MDS 9000 Series Multilayer Switches are affected in versions prior to 8.2(1). Nexus 3000 Series Switches are affected in versions prior to 7.0(3)I7(1). Nexus 3500 Platform Switches are affected in versions prior to 7.0(3)I7(2). Nexus 7000 and 7700 Series Switches are affected in versions prior to 8.2(1). Nexus 9000 Series Switches in Standalone NX-OS Mode are affected in versions prior to 7.0(3)I7(1). Cisco UCS 6200 and 6300 Fabric Interconnect devices are affected in versions prior to 3.2(2b).
