漏洞描述
中文描述:
Cisco IOS和Cisco IOS XR都是美国思科（Cisco）公司的一套为其网络设备开发的操作系统。 Cisco IOS XR 存在安全漏洞，该漏洞源于映像验证检查过程中存在代码执行漏洞。经过身份验证的攻击者可利用该漏洞在底层操作系统上执行任意代码。
英文描述:
A vulnerability in Cisco IOS XR Software image verification checks could allow an authenticated, local attacker to execute arbitrary code on the underlying operating system. This vulnerability is due to a time-of-check, time-of-use (TOCTOU) race condition when an install query regarding an ISO image is performed during an install operation that uses an ISO image. An attacker could exploit this vulnerability by modifying an ISO image and then carrying out install requests in parallel. A successful exploit could allow the attacker to execute arbitrary code on an affected device.
