Recently, DefenseCode researchers have uncovered a high-risk Broadcom UPnP stack remote root vulnerability.The vulnerability is located within the wanipc and wanppp modules of the Broadcom UPnP stack, which is used by manufacturers that deliver routers based on the Broadcom chipset.
The remote preauth format string vulnerability in the Broadcom UPnP stack can be exploited to write arbitrary values to an arbitrary memory address, and also to remotely read router memory. When exploited, it allows an unauthenticated attacker to execute arbitrary code under the root account.
