Frequently Asked Questions
Who is realistically exposed to exploitation?
HPE Networking Instant On AP deployments are exposed where an attacker can operate on an adjacent network and reach the PAPI protocol used to access the CLI. The issue does not require authentication or user interaction.
What level of access can successful exploitation provide?
A successful attacker can inject commands and execute arbitrary commands as a privileged user on the underlying operating system. The stated impact includes high confidentiality, integrity, and availability impact.
Does exploitation require valid credentials or a complex attack path?
No. The vulnerability is described as unauthenticated, with low attack complexity, and is triggered by specially crafted packets sent by an adjacent attacker.
