CVE-2025-48707: Stormshield Network Security Authentication Bypass Vulnerability

Overview

The cybersecurity vulnerability identified as CVE-2025-48707 is a critical threat to Stormshield Network Security (SNS) systems running on versions prior to 5.0.1. The vulnerability pertains to the TPM authentication process, which, under specific HA use cases, results in shared secret among administrators. This flaw could potentially lead to unauthorized system access and subsequent data leakage, thus posing a significant risk to the confidentiality and integrity of the systems in question.

How the Exploit Works

The exploit works by taking advantage of the TPM authentication process in certain HA use cases. Normally, the TPM authentication information is unique to each administrator. However, due to this vulnerability, the same secret can be shared among multiple administrators. An attacker can leverage this flaw to gain unauthorized access to the system, impersonate an administrator, and potentially compromise the system or leak sensitive data.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. Please note that this is a hypothetical scenario meant to illustrate the nature of the vulnerability and is not an actual exploit code.

# Attacker gains network access
attacker@host:~$ ssh user@target.example.com
# Attacker uses shared secret to bypass TPM authentication
attacker@host:~$ sudo sns_tpm_auth --use-shared-secret
# Attacker now has unauthorized administrative access
attacker@host:~$ sudo whoami
root
