vulnerable.
IntelliShield Analysis
To exploit this vulnerability, an attacker must authenticate to the targeted
device. This access requirement reduces the likelihood of a successful
exploit.
A successful exploit could allow the attacker to access root credentials on

complete control of the device.
Cisco indicates through the CVSS score that functional exploit code exists;
however, the code is not known to be publicly available.
Vendor Announcements
Cisco has released bug ID CSCuv21819 for registered users, which contains
additional details and an up-to-date list of affected product versions.
Impact
An authenticated, remote attacker could exploit this vulnerability to access
sensitive information stored on an affected device. A successful exploit could
be used to conduct further attacks.
Technical Information
