Cisco IOS XE Software IOx Guest Shell USB SSD Namespace Protection Privilege Escalation Vulnerability

A vulnerability in the file system on the pluggable USB 3.0 Solid State Drive (SSD) for Cisco IOS XE Software could allow an authenticated, physical attacker to remove the USB 3.0 SSD and modify sensitive areas of the file system, including the namespace container protections. The vulnerability occurs because the USB 3.0 SSD control data is not stored on the internal boot flash. An attacker could exploit this vulnerability by removing the USB 3.0 SSD, modifying or deleting files on the USB 3.0 SSD by using another device, and then reinserting the USB 3.0 SSD on the original device. A successful exploit could allow the attacker to remove container protections and perform file actions outside the namespace of the container with root privileges.

访问控制不恰当

Cisco IOS XE 文件系统访问控制错误漏洞

Cisco IOS和IOS XE都是美国思科（Cisco）公司的产品。CLI是其中的一个命令行界面。 Cisco IOS XE软件的可插拔USB 3.0固态驱动器（SSD）上的文件系统存在访问控制错误漏洞，该漏洞源于USB 3.0 SSD控制数据未存储在内部引导闪存中。 攻击者利用该漏洞删除USB 3.0 SSD，使用其他设备修改或删除USB 3.0 SSD上的文件，然后在原始设备上重新插入USB 3.0 SSD。
