Summary
by MITRE • 07/07/2026
An Incorrect Privilege Assignment (CWE-266) vulnerability in the Command Centre Server allows an authenticated operator with limited privileges to perform some operations that they would not normally be authorized to perform. Version of Command Centre affected: 9.50 prior to vEL9.50.1587(MR1), 9.40 prior to vEL9.40.3130(MR3), 9.30 prior to vEL9.30.3983(MR5), 9.20 prior to vEL9.20.4349(MR7), all versions of 9.10.

This vulnerability represents a critical privilege escalation flaw in the Command Centre Server software where authenticated users with limited permissions can execute operations beyond their designated authorization levels. The issue manifests as an incorrect privilege assignment that allows malicious or compromised operators to bypass intended access controls and perform administrative functions they should not normally be permitted to execute. This misconfiguration creates a pathway for unauthorized activities within the system's operational environment.
The technical nature of this vulnerability falls under CWE-266, which specifically addresses situations where software incorrectly assigns privileges to users or processes, leading to elevated access rights beyond what is intended by the security design. The affected versions span multiple release lines including 9.50 through 9.10, with specific patch levels indicating when fixes were introduced to address the privilege assignment error. This widespread impact across multiple versions suggests a fundamental flaw in the permission model implementation rather than an isolated incident.
The operational impact of this vulnerability extends beyond simple unauthorized access as it enables attackers to potentially escalate their privileges within the Command Centre environment. An authenticated operator could leverage this weakness to perform critical system functions such as modifying user permissions, accessing restricted data sets, or executing administrative commands that should be limited to privileged users only. This capability significantly undermines the security posture of systems relying on this software for command and control operations.
Security professionals should consider this vulnerability in relation to ATT&CK framework techniques such as privilege escalation and defense evasion where attackers might exploit misconfigured permissions to maintain persistent access. Organizations using these affected versions should immediately implement the recommended patches corresponding to their specific version lines, with particular attention to the MR (Maintenance Release) versions that contain the necessary fixes. Additionally, implementing principle of least privilege controls, regular access reviews, and monitoring for unauthorized administrative activities can help detect exploitation attempts and reduce the attack surface.
