Authenticated Path Traversal Vulnerability Leads to Remote Code Execution in AOS-CX

An authenticated path traversal vulnerability exists in AOS-CX. Successful exploitation of this vulnerability allows an attacker to copy arbitrary files to a user readable location from the command line interface of the underlying operating system, which could lead to remote code execution.

The Diffie-Hellman Key Agreement Protocol allows remote attackers (from the client side) to send arbitrary numbers that are actually not public keys, and trigger expensive server-side DHE modular-exponentiation calculations, aka a D(HE)at or D(HE)ater attack. The client needs very little CPU resources and network bandwidth. The attack may be more disruptive in cases where a client can require a server to select its largest supported key size. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE.

Authenticated Command Injection Vulnerability in AOS-CX Command Line Interface

An authenticated command injection vulnerability exists in the AOS-CX command line interface. Successful exploitation of this vulnerability results in the ability to execute arbitrary commands on the underlying operating system as a privileged user on the affected switch. This allows an attacker to fully compromise the underlying operating system on the device running AOS-CX.
