A vulnerability in the hxterm service of Cisco HyperFlex Software could allow an unauthenticated, local attacker to gain root access to all nodes in the cluster. The vulnerability is due to insufficient authentication controls. An attacker could exploit this vulnerability by connecting to the hxterm service as a non-privileged, local user. A successful exploit could allow the attacker to gain root access to all member nodes of the HyperFlex cluster. This vulnerability affects Cisco HyperFlex Software Releases prior to 3.5(2a).
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

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:
