Last modified

CVE-2018-7081 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. A remote code execution vulnerability is present in network-listening components in some versions of ArubaOS. An attacker with the ability to transmit specially-crafted IP traffic to a mobility controller could exploit this vulnerability and cause a process crash or to execute arbitrary code within the underlying operating system with full system privileges. EPSS estimates a 5.85% chance of exploitation in the next 30 days.

Description

A remote code execution vulnerability is present in network-listening components in some versions of ArubaOS. An attacker with the ability to transmit specially-crafted IP traffic to a mobility controller could exploit this vulnerability and cause a process crash or to execute arbitrary code within the underlying operating system with full system privileges. Such an attack could lead to complete system compromise. The ability to transmit traffic to an IP interface on the mobility controller is required to carry out an attack. The attack leverages the PAPI protocol (UDP port 8211). If the mobility controller is only bridging L2 traffic to an uplink and does not have an IP address that is accessible to the attacker, it cannot be attacked.
