CVE-2018-7081: Arubanetworks Arubaos: Remote code execution

CVE-2018-7081 is rated critical with a CVSS v3.1 base score of 9.8 and affects Arubanetworks Arubaos. Per its scoring, it can be exploited over the network, without authentication, without any user interaction. The scored impact on confidentiality, integrity and availability is the highest available.

Vulnerability 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.

Severity breakdown

CVSS v3.1 9.8: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

  • Attack vector: Network. Exploitable remotely over the network, with no need for local or physical access.
  • Attack complexity: Low. No special conditions; the attack can be repeated reliably.
  • Privileges required: None. No account or prior access is needed.
  • User interaction: None. No action from any user is needed.
  • Scope: Unchanged. Impact stays within the vulnerable component.
  • Confidentiality impact: High. Total loss of confidentiality; sensitive data can be fully disclosed.
  • Integrity impact: High. Total loss of integrity; data or system state can be fully modified.
  • Availability impact: High. Total loss of availability; the component can be shut down.

Underlying weakness

CWE-20: Improper Input Validation

The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
