漏洞描述
中文描述:
Cisco Products Snort是美国思科(Cisco)公司的一个用于思科产品的Snort引擎。 Cisco Products Snort 存在安全漏洞,该漏洞源于在没有适当约束的情况下配置规则时,对Block with Reset或Interactive Block with Reset操作的不当处理造成的。攻击者可以通过向受影响的设备发送精心设计的 IP 数据包来利用此漏洞。成功的利用可能允许攻击者导致直通流量被丢弃。
英文描述:
Multiple Cisco products are affected by a vulnerability in Snort rules that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.The vulnerability is due to improper handling of the Block with Reset or Interactive Block with Reset actions if a rule is configured without proper constraints. An attacker could exploit this vulnerability by sending a crafted IP packet to the affected device. A successful exploit could allow the attacker to cause through traffic to be dropped. Note: Only products with Snort3 configured and either a rule with Block with Reset or Interactive Block with Reset actions configured are vulnerable. Products configured with Snort2 are not vulnerable.
