Detail

A vulnerability in the Cisco Network Plug and Play application of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to gain unauthorized access to sensitive data by using an invalid certificate.

The vulnerability is due to insufficient certificate validation by the affected software. An attacker could exploit this vulnerability by supplying a crafted certificate to an affected device. A successful exploit could allow the attacker to conduct man-in-the-middle attacks to decrypt confidential information on user connections to the affected software.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
