Executive brief
HPE Networking Fabric Composer is a network management platform used to configure and control fabric switches. A flaw in the API allows authenticated operators with low-level privileges to bypass security controls and escalate to full administrative access, potentially enabling an insider or compromised account to take complete control of the network infrastructure.
Technical details
A command sanitization bypass vulnerability exists in the API of HPE Networking Fabric Composer. The vulnerability allows authenticated users with low privilege operator roles to escalate their permissions to administrative level through improper input validation or filtering of API commands. The attack requires valid authentication credentials and network access to the API endpoint. Successful exploitation grants an attacker full administrative control of the affected system, enabling complete compromise of network management capabilities. A patch is expected from HPE to address the input validation flaw.
