漏洞描述
中文描述:
Broadcom Media exChange是一个路由器的固件。 Broadcom Media exChange 中TrustZone存在安全漏洞，攻击者可利用此漏洞提升权限并执行任意代码。
英文描述:
The TrustZone implementation in certain Broadcom MediaxChange firmware could allow an unauthenticated, physically proximate attacker to achieve arbitrary code execution in the TrustZone Trusted Execution Environment (TEE) of an affected device. This, for example, affects certain Cisco IP Phone and Wireless IP Phone products before 2021-07-07. Exploitation is possible only when the attacker can disassemble the device in order to control the voltage/current for chip pins.
