漏洞描述
中文描述:
Cisco Email Security Appliance(ESA)是美国思科(Cisco)公司的一个电子邮件安全设备。AsyncOS Software是运行在其中的一套操作系统。 Cisco Email Security Appliance中的AsyncOS Software存在输入验证错误漏洞,该漏洞源于对SPF消息程序缺少完整的输入和验证检查机制。远程攻击者可通过发送特制的SPF数据包利用该漏洞绕过所配置的头过滤器。
英文描述:
A vulnerability in the Sender Policy Framework (SPF) functionality of Cisco AsyncOS Software for Cisco Email Security Appliances (ESA) could allow an unauthenticated, remote attacker to bypass configured user filters on the device. The vulnerability is due to incomplete input and validation checking mechanisms for certain SPF messages that are sent to an affected device. An attacker could exploit this vulnerability by sending a customized SPF packet to an affected device. A successful exploit could allow the attacker to bypass the header filters that are configured for the affected device, which could allow malicious content to pass through the device.
