CVE-2022-20775— Cisco SD-WAN Software Privilege Escalation Vulnerability

Quick assessment

Affected
Cisco Cisco Catalyst SD-WAN
Exploitation
Confirmed exploitation in the wild; remediate immediately
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Cisco SD-WAN是美国思科（Cisco）公司的一种高度安全的云规模架构，具有开放性、可编程性和可扩展性。 Cisco SD-WAN Software存在路径遍历漏洞，该漏洞源于对应用程序CLI中的命令的访问控制不当，可能允许经过身份验证的本地攻击者获得提升的权限，成功利用此漏洞可以让攻击者执行任意命令。
