Published Updated By the CyberSecBulletin desk

CVE-2022-23679 is a high-severity cross-site request forgery vulnerability in Aruba CX 6200F Switch Series; Aruba 6300 Switch Series; Aruba 6400 Switch Series; Aruba 8325 Switch Series; Aruba 8400 Switch Series; Aruba CX 8360 Switch Series; ArubaOS-CX Switches; from Aruba CX 6200F Switch Series; Aruba 6300 Switch Series; Aruba 6400 Switch Series; Aruba 8325 Switch Series; Aruba 8400 Switch Series; Aruba CX 8360 Switch Series; ArubaOS-CX Switches, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. There is no confirmed exploitation so far. EPSS estimates a 0.43% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Aos-cx to 10.06.0210 or 10.08.1070 or 10.09.1030 or 10.10.1000, whichever matches your release line, or a later version.
  2. Read the advisory on arubanetworks.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
  4. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

AOS-CX lacks Anti-CSRF protections in place for state-changing operations. This can potentially be exploited by an attacker to execute commands in the context of another user in ArubaOS-CX Switches version(s): AOS-CX 10.10.xxxx: 10.10.0002 and below, AOS-CX 10.09.xxxx: 10.09.1020 and below, AOS-CX 10.08.xxxx: 10.08.1060 and below, AOS-CX 10.06.xxxx: 10.06.0200 and below. Aruba has released upgrades for ArubaOS-CX Switch Devices that address this security vulnerability.

The underlying weakness: Cross-Site Request Forgery

The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.

How developers prevent this class of flaw

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, use anti-CSRF packages such as the OWASP CSRFGuard. Another example is the ESAPI Session Management control, which includes a component for CSRF.
  • Ensure that the application is free of cross-site scripting issues (CWE-79), because most CSRF defenses can be bypassed using attacker-controlled script.
  • Generate a unique nonce for each form, place the nonce into the form, and verify the nonce upon receipt of the form. Be sure that the nonce is not predictable (CWE-330).
