Updated17 Jun 2026

Description

A vulnerability in role-based access control of Cisco Integrated Management Controller (IMC) Supervisor, Cisco UCS Director, and Cisco UCS Director Express for Big Data could allow a read-only authenticated, remote attacker to disable user accounts on an affected system. The vulnerability is due to incorrect allocation of the enable/disable action button under the role-based access control code on an affected system. An attacker could exploit this vulnerability by authenticating as a read-only user and then updating the roles of other users to disable them. A successful exploit could allow the attacker to disable users, including administrative users.

Waratek protection

Outside Waratek scope

A Java vulnerability, but not one Waratek protects. It affects only Java on a user's desktop (applets, Web Start, JavaFX, the installer), sits in a product the Waratek agent can't be installed into, or is in a package we don't expect in business applications. The decision below says which.

  • Protection none
  • Action not pursued none
  • Review automated Upstream data
  • Record active
Decided by The only affected product being a sealed appliance image, where Java runs but no -javaagent can be attached
Finding This CVE names only products the Waratek agent cannot be installed into (cisco/integrated_management_controller_supervisor, cisco/ucs_director). They ship as sealed appliance images or as native code with no application JVM, so there is no start-up line to add -javaagent to. The vulnerability may well be a Java one; it is permanently out of ARMR's reach rather than outside its subject.
