CVE-2025-23051: AOS-8/AOS-10 Parameter Injection RCE Flaw

CVE-2025-23051 Overview

An authenticated parameter injection vulnerability exists in the web-based management interface of the AOS-8 and AOS-10 Operating Systems used in HPE Aruba networking equipment. This vulnerability allows an authenticated user with access to the management interface to inject malicious parameters that can be leveraged to overwrite arbitrary system files. The flaw is classified under CWE-94 (Improper Control of Generation of Code), indicating a code injection weakness at its core.

Critical Impact

Successful exploitation enables authenticated attackers to overwrite arbitrary system files, potentially leading to complete system compromise, persistent backdoor installation, or denial of service conditions on affected network infrastructure devices.

Affected Products

• HPE Aruba AOS-8 Operating System
• HPE Aruba AOS-10 Operating System
• Aruba Access Points and Controllers running vulnerable AOS versions

Technical Details for CVE-2025-23051

Vulnerability Analysis

This vulnerability stems from improper handling of user-supplied parameters within the web-based management interface of AOS-8 and AOS-10 systems. The attack requires network access and high-level privileges (authenticated user), but once authenticated, an attacker can exploit the parameter injection flaw without any user interaction. The vulnerability affects the confidentiality, integrity, and availability of the target system, as successful exploitation allows arbitrary file overwrites.

The web management interface fails to properly sanitize or validate certain input parameters before processing them in system operations. This allows an authenticated attacker to craft malicious requests that inject additional parameters or modify existing ones, ultimately manipulating file system operations to overwrite critical system files.

Root Cause

The root cause lies in improper input validation within the web-based management interface. When processing authenticated requests, the application does not adequately sanitize user-controlled parameters before using them in file system operations. This allows parameter values to escape their intended context and influence file path or content operations, enabling arbitrary file overwrites.

The vulnerability is classified under CWE-94 (Improper Control of Generation of Code), which encompasses code injection vulnerabilities where user input improperly influences the generation or execution of code or commands.

Attack Vector

The attack vector is network-based, requiring the attacker to have authenticated access to the web-based management interface. The attack flow typically involves:

1. The attacker authenticates to the AOS-8 or AOS-10 web management interface with valid credentials
2. The attacker identifies vulnerable parameters in specific management interface requests
3. Crafted requests containing injected parameters are sent to the target system
4. The injected parameters manipulate file system operations
5. Arbitrary system files are overwritten with attacker-controlled content

The parameter injection mechanism allows attackers to escape the intended parameter context and specify alternative file paths or content, bypassing normal access controls for file operations. For detailed technical information, refer to the HPE Security Bulletin.

Detection Methods for CVE-2025-23051

Indicators of Compromise

• Unexpected modifications to system configuration files or binaries on AOS devices
• Unusual authenticated session activity in web management interface logs
• Anomalous HTTP requests to management interface endpoints containing encoded or malformed parameters
• System instability or unexpected behavior following authenticated management sessions

Detection Strategies

• Monitor web management interface access logs for requests with abnormal parameter structures or lengths
• Implement file integrity monitoring on critical system files to detect unauthorized modifications
• Deploy network intrusion detection signatures for anomalous parameter patterns in AOS management traffic
• Audit authenticated user activities on network management interfaces for suspicious behavior

Monitoring Recommendations

• Enable detailed logging for all web management interface authentication and request activity
• Configure SIEM rules to alert on multiple failed parameter validation events or unusual file system operations
• Establish baseline behavior for management interface usage and alert on deviations
• Monitor for unauthorized configuration changes or unexpected file modifications on AOS systems

How to Mitigate CVE-2025-23051

Immediate Actions Required

• Review the HPE Security Bulletin for specific patch and mitigation guidance
• Restrict access to the web-based management interface to trusted networks and administrators only
• Audit all accounts with access to the management interface and revoke unnecessary privileges
• Enable enhanced logging and monitoring for management interface access

Patch Information

HPE has released security updates to address this vulnerability in AOS-8 and AOS-10. Administrators should consult the HPE Security Bulletin for specific version information and download instructions. Apply the appropriate patches immediately to all affected Aruba devices in your environment.

Workarounds

• Implement network segmentation to restrict management interface access to dedicated management VLANs
• Use access control lists (ACLs) to limit which IP addresses can reach the management interface
• Consider disabling the web-based management interface and using CLI-only management where feasible
• Deploy a web application firewall (WAF) or reverse proxy to filter malicious parameter injection attempts

# Example: Restrict management interface access via ACL (consult your specific AOS documentation)
# This is a conceptual example - refer to HPE documentation for exact syntax
ip access-list session mgmt-restrict
  any host <management-ip> svc-https permit
  any any svc-https deny
