EUVD-2025-21430

Comprehensive Technical Analysis of EUVD-2025-21430

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-21430 affects Riverbed SteelCentral NetProfiler and NetExpress 10.8.7 virtual appliances. It is classified as an authenticated multi-stage remote code execution (RCE) vulnerability. The severity is rated with a CVSS Base Score of 10.0, indicating a critical risk. The vulnerability involves a SQL injection in the login endpoint, which can be exploited to create a new user account. This user can then trigger a command injection vulnerability to execute arbitrary commands, potentially leading to privilege escalation to root access.

CVSS Vector Breakdown:

• AV:N - Attack Vector: Network
• AC:L - Attack Complexity: Low
• AT:N - Attack Technique: Network
• PR:N - Privileges Required: None
• UI:N - User Interaction: None
• VC:H - Vulnerability Confidentiality: High
• VI:H - Vulnerability Integrity: High
• VA:H - Vulnerability Availability: High
• SC:H - Scope Change: High
• SI:H - Scope Integrity: High
• SA:H - Scope Availability: High

2. Potential Attack Vectors and Exploitation Methods

1. SQL Injection:

   • The attacker exploits a SQL injection vulnerability in the /api/common/1.0/login endpoint to create a new user account in the appliance database.

2. Command Injection:

   • The newly created user account is used to trigger a command injection vulnerability in the /index.php?page=licenses endpoint, allowing the execution of arbitrary commands.

3. Privilege Escalation:

   • The attacker can escalate privileges to root by exploiting an insecure sudoers configuration that allows the mazu user to execute arbitrary commands as root via SSH key extraction and command chaining.

3. Affected Systems and Software Versions

• Products:

  • Riverbed SteelCentral NetProfiler 10.8.7
  • Riverbed SteelCentral NetExpress 10.8.7

6. Technical Details for Security Professionals

SQL Injection Exploitation:

• The SQL injection vulnerability in the /api/common/1.0/login endpoint can be exploited using crafted SQL queries to manipulate the database and create a new user account.

Command Injection Exploitation:

• The command injection vulnerability in the /index.php?page=licenses endpoint can be triggered by injecting malicious commands through the newly created user account.

Privilege Escalation:

• The insecure sudoers configuration allows the mazu user to execute arbitrary commands as root. This can be exploited by extracting SSH keys and chaining commands to gain root access.
