| Vector | AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Cisco Identity Services Engine (affected versions not specified)
Description
Insufficient validation of user-supplied input allows an authenticated remote attacker with at least Read Only Admin credentials to execute arbitrary commands on the underlying operating system. This is achieved by sending a crafted HTTP request to the device. A successful exploit can grant user-level access to the operating system, which can then be elevated to root privileges. In single-node deployments, this may lead to a denial of service (DoS) condition, preventing unauthenticated endpoints from accessing the network until the node is restored.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
