漏洞描述
中文描述:
Cisco Firepower Management Center（FMC）等都是美国思科（Cisco）公司的产品。Cisco Firepower Management Center是新一代防火墙管理中心软件。Cisco Firepower Threat Defense（FTD）是一套提供下一代防火墙服务的统一软件。Cisco?FirePOWER Services Software for ASA是一套用于Cisco ASA设备的安全威胁防护软件。 Cisco FTD、Cisco FirePOWER Services Software for ASA和Cisco FMC中的normalization功能存在权限许可和访问控制问题漏洞，该漏洞源于程序没有充分地对基于文本的payload进行标准化处理。远程攻击者可通过发送流量利用该漏洞绕过过滤机制，向受保护的系统发送恶意的payloads。
英文描述:
A vulnerability in the normalization functionality of Cisco Firepower Threat Defense Software, Cisco FirePOWER Services Software for ASA, and Cisco Firepower Management Center Software could allow an unauthenticated, remote attacker to bypass filtering protections. The vulnerability is due to insufficient normalization of a text-based payload. An attacker could exploit this vulnerability by sending traffic that contains specifically obfuscated payloads through an affected device. An exploit could allow the attacker to bypass filtering and deliver malicious payloads to protected systems that would otherwise be blocked.
