CVE-2017-12261
HighSummary
A vulnerability in the restricted shell of the Cisco Identity Services Engine (ISE) accessible via SSH allows an authenticated local attacker to run arbitrary CLI commands with elevated privileges. The issue is due to incomplete input validation of user input for CLI commands issued at the restricted shell.
Risk Assessment
An attacker with valid user credentials could exploit this vulnerability to gain elevated privileges, potentially leading to serious security breaches within the system.
Recommendation
It is recommended to update Cisco ISE to the latest version to mitigate this vulnerability and to monitor access logs for unauthorized login attempts.

A stored cross-site scripting (XSS) weakness in Kiteworks Core could allow an unauthenticated attacker to store crafted content that later executes arbitrary JavaScript in the authenticated session of an administrator who views the affected page. This could have permitted the attacker to gain full administrative control, including the creation of a new administrative account.
Original NVD description (English source)
A vulnerability in the restricted shell of the Cisco Identity Services Engine (ISE) that is accessible via SSH could allow an authenticated, local attacker to run arbitrary CLI commands with elevated privileges. The vulnerability is due to incomplete input validation of the user input for CLI commands issued at the restricted shell. An attacker could exploit this vulnerability by authenticating to the targeted device and executing commands that could lead to elevated privileges. An attacker would need valid user credentials to the device to exploit this vulnerability. The vulnerability affects the following Cisco Identity Services Engine (ISE) products running Release 1.4, 2.0, 2.0.1, 2.1.0: ISE, ISE Express, ISE Virtual Appliance. Cisco Bug IDs: CSCve74916.
