Assigner: Cisco Systems, Inc.

Description
A vulnerability in the IPv6 Router Advertisement (RA) packet processing of Cisco Access Point Software could allow an unauthenticated, adjacent attacker to modify the IPv6 gateway on an affected device. This vulnerability is due to a logic error in the processing of IPv6 RA packets that are received from wireless clients. An attacker could exploit this vulnerability by associating to a wireless network and sending a series of crafted IPv6 RA packets. A successful exploit could allow the attacker to temporarily change the IPv6 gateway of an affected device. This could also lead to intermittent packet loss for any wireless clients that are associated with the affected device.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability exists in the IPv6 Router Advertisement (RA) packet processing of Cisco Access Point Software. It allows an unauthenticated, adjacent attacker to modify the IPv6 gateway on an affected device by exploiting a logic error when processing IPv6 RA packets received from wireless clients. The attacker can associate with the wireless network and send crafted IPv6 RA packets to temporarily change the IPv6 gateway.


How can this vulnerability impact me? :

Exploiting this vulnerability could allow an attacker to temporarily change the IPv6 gateway of the affected device, which may cause intermittent packet loss for wireless clients connected to that device. This could disrupt network connectivity and degrade the user experience.
