CVE-2021-1433 (CNNVD-202103-1399)
中文标题:
Cisco IOS XE 缓冲区错误漏洞
英文标题:
Cisco IOS XE SD-WAN Software vDaemon Buffer Overflow Vulnerability
漏洞描述
中文描述:
Cisco IOS XE是美国思科(Cisco)公司的一套为其网络设备开发的操作系统。 Cisco IOS XE 存在安全漏洞,该漏洞源于设备处理流量时边界检查不足。攻击者可利用该漏洞在受影响的设备上造成缓冲区溢出。
英文描述:
A vulnerability in the vDaemon process in Cisco IOS XE SD-WAN Software could allow an unauthenticated, remote attacker to cause a buffer overflow on an affected device. This vulnerability is due to insufficient bounds checking when the device processes traffic. An attacker could exploit this vulnerability by sending crafted traffic to the device. The attacker must have a man-in-the-middle position between Cisco vManage and an associated device that is running an affected version of Cisco IOS XE SD-WAN Software. An exploit could allow the attacker to conduct a controllable buffer overflow attack (and possibly execute arbitrary commands as the root user) or cause a device reload, resulting in a denial of service (DoS) condition.
