CVSS 2.x

A vulnerability in the Live Data server of Cisco Unified Intelligence Center could allow an unauthenticated, local attacker to read and modify data in a repository that belongs to an internal service on an affected device. This vulnerability is due to insufficient access control implementations on cluster configuration CLI requests. An attacker could exploit this vulnerability by sending a cluster configuration CLI request to specific directories on an affected device. A successful exploit could allow the attacker to read and modify data that is handled by an internal service on the affected device.


The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

Extended Description

Access control involves the use of several protection mechanisms such as:

When any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc. There are two distinct behaviors that can introduce access control weaknesses:

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
