- A vulnerability in Cisco IOS XE Software could allow an unauthenticated, remote attacker to log in to a device running an affected release of Cisco IOS XE Software with the default username and password that are used at initial boot, aka a Static Credential Vulnerability. The vulnerability is due to an undocumented user account with privilege level 15 that has a default username and password. An attacker could exploit this vulnerability by using this account to remotely connect to an affected device. A successful exploit could allow the attacker to log in to the device with privilege level 15 access. This vulnerability affects Cisco devices that are running a vulnerable release of Cisco IOS XE Software Release 16.x. This vulnerability does not affect Cisco IOS XE Software releases prior to Release 16.x. Cisco Bug IDs: CSCve89880.
