HPE Aruba Networking AOS-CX: Session Fixation
CVE-2025-37159 is a high-severity session fixation vulnerability in HPE Aruba Networking AOS-CX from Hewlett Packard Enterprise, with a CVSS 3.1 base score of 7.3 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. Affected HPE Aruba Networking AOS-CX versions: 10.16.0000 through 10.16.1000; 10.15.0000 through 10.15.1020; 10.14.0000 through 10.14.1050, and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.27% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Arubaos-cx to 10.10.1170 or 10.13.1101 or 10.14.1060 or 10.15.1030, whichever matches your release line, or a later version.
- Read the advisory on support.hpe.com for workarounds and exact fixed builds.
- 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
A vulnerability in the web management interface of the AOS-CX OS user authentication service could allow an authenticated remote attacker to hijack an active user session. Successful exploitation may enable the attacker to maintain unauthorized access to the session, potentially leading to the view or modification of sensitive configuration data.

The underlying weakness: Session Fixation
Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions.
How developers prevent this class of flaw
- Invalidate any existing session identifiers prior to authorizing a new user session.
- For platforms such as ASP that do not generate new values for sessionid cookies, utilize a secondary cookie. In this approach, set a secondary cookie on the user's browser to a random value and set a session variable to the same value. If the session variable and the cookie value ever don't match, invalidate the session, and force the user to log on again.
- Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
