Name of the Vulnerable Software and Affected Versions Cisco IOS Software and Cisco IOS XE Software (affected versions not specified)

Description A vulnerability in the TACACS+ client subsystem could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to improper handling of crafted TACACS+ response packets by the affected software. An attacker could exploit this vulnerability by injecting a crafted TACACS+ packet into an existing TACACS+ session between an affected device and a TACACS+ server or by impersonating a known, valid TACACS+ server and sending a crafted TACACS+ packet to an affected device when establishing a connection to the device. To exploit this vulnerability, the attacker must know the shared TACACS+ secret and the crafted packet must be sent in response to a TACACS+ request from a TACACS+ client.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
