HPE Aruba Networking Access Points, Instant…: Improper Neutralization of Special Elements used in a Command

Published Updated By the CyberSecBulletin desk

CVE-2024-47460 is a critical-severity improper neutralization of special elements used in a command vulnerability in HPE Aruba Networking Access Points, Instant AOS-8, and AOS-10 from Hewlett Packard Enterprise, with a CVSS 3.1 base score of 9.0 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected HPE Aruba Networking Access Points, Instant AOS-8, and AOS-10 versions: AOS-10.4.x.x: 10.4.1.4 and below through <=10.4.1.4; Instant AOS-8.12.x.x: 8.12.0.2 and below through <=8.12.0.2; Instant AOS-8.10.x.x: 8.10.0.13 and below through <=8.10.0.13. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 1.39% chance of exploitation within 30 days, higher than 73% of scored CVEs.

Patch this week

Critical severity: a successful attack would have severe impact.

What to do

  1. Update arubaos to 10.4.0.0 or 10.7.0.0, whichever matches your release line, or a later version.
  2. Update instant to 6.6.0.0 or 8.10.0.0 or 8.12.0.0, whichever matches your release line, or a later version.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Command injection vulnerability in the underlying CLI service could lead to unauthenticated remote code execution by sending specially crafted packets destined to the PAPI (Aruba's Access Point management protocol) UDP port (8211). Successful exploitation of this vulnerability results in the ability to execute arbitrary code as a privileged user on the underlying operating system.

The underlying weakness: Improper Neutralization of Special Elements used in a Command

The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.

How developers prevent this class of flaw

  • If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • If possible, ensure that all external commands called from the program are statically created.
  • Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
