漏洞描述
中文描述:

Cisco IOS XE Software是美国思科（Cisco）公司的一个操作系统。用于企业有线和无线访问，汇聚，核心和WAN的单一操作系统，Cisco IOS XE降低了业务和网络的复杂性。 Cisco IOS XE Software 存在安全漏洞，该漏洞源于在检索用于图像签名验证的公开发布密钥时发生错误。

英文描述:

A vulnerability in Cisco IOS XE Software for Cisco Catalyst 9300 Series Switches could allow an authenticated, local attacker with level-15 privileges or an unauthenticated attacker with physical access to the device to execute persistent code at boot time and break the chain of trust. This vulnerability is due to errors that occur when retrieving the public release key that is used for image signature verification. An attacker could exploit this vulnerability by modifying specific variables in the Serial Peripheral Interface (SPI) flash memory of an affected device. A successful exploit could allow the attacker to execute persistent code on the underlying operating system. Note: In Cisco IOS XE Software releases 16.11.1 and later, the complexity of an attack using this vulnerability is high. However, an attacker with level-15 privileges could easily downgrade the Cisco IOS XE Software on a device to a release that would lower the attack complexity.
