CVE-2025-37102: HPE Instant On Access Points RCE Flaw

CVE-2025-37102 Overview

An authenticated command injection vulnerability exists in the Command Line Interface (CLI) of HPE Networking Instant On Access Points. This vulnerability allows a remote attacker with elevated privileges to execute arbitrary commands on the underlying operating system as a highly privileged user, potentially leading to complete system compromise.

Critical Impact

Authenticated attackers with elevated privileges can achieve arbitrary command execution on the underlying operating system with highly privileged access, enabling full device takeover.

Technical Details for CVE-2025-37102

Vulnerability Analysis

This vulnerability is classified as CWE-77 (Improper Neutralization of Special Elements used in a Command), commonly known as Command Injection. The flaw exists within the Command Line Interface of HPE Networking Instant On Access Points, where user-supplied input is improperly sanitized before being passed to system shell commands.

When an authenticated user with elevated privileges interacts with specific CLI commands, their input may be incorporated into operating system commands without adequate validation or escaping. This allows an attacker to inject additional commands that execute with the privileges of the access point's underlying system processes—typically root or equivalent elevated permissions.

The network-accessible nature of this vulnerability means attackers can exploit it remotely, though the requirement for elevated privileges limits the immediate attack surface. Organizations should consider that compromised administrator credentials or insider threats represent viable attack scenarios.

Root Cause

The root cause stems from improper input validation and sanitization within the CLI command processing logic. User-supplied arguments are concatenated directly into shell commands without proper escaping or parameterization, allowing shell metacharacters to break out of the intended command context and inject malicious commands.

Attack Vector

The attack requires network access to the HPE Instant On Access Point's management interface and valid credentials with elevated privileges. An attacker who has obtained such credentials—whether through phishing, credential stuffing, or insider access—can craft malicious CLI input containing shell metacharacters and commands. These injected commands execute in the security context of the access point's operating system with high privileges, enabling activities such as:

• Installing persistent backdoors or malware
• Exfiltrating network traffic and sensitive configurations
• Pivoting to attack other network devices
• Disrupting wireless network services

The vulnerability does not require user interaction beyond the attacker's own actions, making it straightforward to exploit once authentication is achieved.

Detection Methods for CVE-2025-37102

Indicators of Compromise

• Unexpected CLI login attempts or sessions from unusual IP addresses or at unusual times
• Anomalous process execution on access points, particularly shell processes spawned by CLI services
• Unusual outbound network connections from access point devices
• Unexpected configuration changes or new administrative accounts on access points

Detection Strategies

• Monitor authentication logs for elevated privilege accounts accessing HPE Instant On Access Points
• Implement network traffic analysis to detect unusual command-and-control patterns from access point devices
• Deploy endpoint detection solutions capable of monitoring embedded Linux systems for suspicious process trees
• Correlate CLI access events with follow-on network activity to identify potential exploitation chains

Monitoring Recommendations

• Enable comprehensive logging on all HPE Instant On Access Points and forward logs to a centralized SIEM
• Establish baseline behavior for administrative access patterns and alert on deviations
• Monitor for file system changes on access points that may indicate persistence mechanisms
• Implement network segmentation to limit the blast radius if an access point is compromised

How to Mitigate CVE-2025-37102

Immediate Actions Required

• Review and restrict which accounts have elevated CLI access to HPE Instant On Access Points
• Audit recent CLI access logs for any suspicious activity or unrecognized sessions
• Implement network segmentation to limit management interface exposure
• Enforce multi-factor authentication for administrative access where supported
• Apply vendor patches immediately upon availability

Patch Information

HPE has published a security bulletin addressing this vulnerability. Administrators should review the HPE Security Document for detailed patch information, affected firmware versions, and upgrade instructions. Apply the recommended firmware updates as soon as possible to remediate this vulnerability.

Workarounds

• Restrict CLI access to trusted management networks only using firewall rules or ACLs
• Disable CLI access entirely if not required for operational purposes
• Implement strong password policies and rotate credentials for privileged accounts
• Monitor and alert on all CLI access attempts until patches can be applied
• Consider placing access points behind a VPN for management access

Organizations should prioritize patching as workarounds only reduce—not eliminate—the risk of exploitation. Continuous monitoring remains essential until the vulnerability is fully remediated.
