CVE-2025-23060 is a high-severity cleartext transmission of sensitive information vulnerability in HPE Aruba Networking ClearPass Policy Manager from Hewlett Packard Enterprise, with a CVSS 3.1 base score of 8.1 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 ClearPass Policy Manager versions: 6.12.0 through <=6.12.3; 6.11.0 through <=6.11.9. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.24% 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 Clearpass Policy Manager to 6.11.10 or 6.12.4, whichever matches your release line, or a later version.
- Read the advisory on support.hpe.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
A vulnerability in HPE Aruba Networking ClearPass Policy Manager may, under certain circumstances, expose sensitive unencrypted information. Exploiting this vulnerability could allow an attacker to perform a man-in-the-middle attack, potentially granting unauthorized access to network resources as well as enabling data tampering.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Cleartext Transmission of Sensitive Information
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
How developers prevent this class of flaw
- Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
- When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
- When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
