CVE-2025-22392: Intel AMT Information Disclosure Flaw

CVE-2025-22392 Overview

CVE-2025-22392 is an out-of-bounds read vulnerability affecting firmware for Intel Active Management Technology (AMT) and Intel Standard Manageability. This memory safety flaw may allow a privileged user to potentially enable information disclosure via network access.

The vulnerability exists within the firmware's memory handling routines, where improper bounds checking can lead to reading data beyond allocated buffer boundaries. While exploitation requires privileged access and network connectivity, successful attacks could result in exposure of sensitive information from firmware memory.

Critical Impact

A privileged attacker with network access could exploit this out-of-bounds read vulnerability to disclose sensitive information from Intel AMT or Standard Manageability firmware memory, potentially exposing configuration data, credentials, or other confidential system information.

Affected Products

• Intel Active Management Technology (AMT) firmware
• Intel Standard Manageability firmware
• Systems with vulnerable Intel vPro platform implementations

Technical Details for CVE-2025-22392

Vulnerability Analysis

This vulnerability is classified as CWE-125 (Out-of-bounds Read), a common memory safety issue where software reads data from a location outside the bounds of the intended buffer. In the context of Intel AMT and Standard Manageability firmware, this flaw occurs when the firmware processes certain network requests without properly validating memory access boundaries.

Intel AMT provides remote management capabilities for enterprise systems, operating at a hardware level below the operating system. This makes vulnerabilities in AMT firmware particularly concerning, as they can persist regardless of OS-level security measures and may be exploitable even when the system is powered off (but connected to power).

The out-of-bounds read could allow an authenticated, privileged attacker to extract memory contents that should not be accessible, potentially revealing sensitive configuration data, cryptographic material, or other confidential information stored in firmware memory regions.

Root Cause

The root cause of CVE-2025-22392 lies in insufficient bounds checking within the Intel AMT and Standard Manageability firmware. When processing network-based requests, the firmware fails to properly validate that memory read operations remain within allocated buffer boundaries. This allows read operations to access adjacent memory regions, exposing data that was not intended to be returned to the requester.

Attack Vector

The attack vector for this vulnerability requires network access and privileged authentication to the Intel AMT or Standard Manageability interface. An attacker would need to:

1. Gain network access to the target system's AMT management interface (typically on port 16992 or 16993)
2. Authenticate with privileged credentials to the management service
3. Send specially crafted requests designed to trigger the out-of-bounds read condition
4. Analyze returned data to extract sensitive information from adjacent memory regions

The network-based attack vector combined with the requirement for privileged access means exploitation is more likely in scenarios where an attacker has already compromised administrative credentials or operates from a position within the management network.

Detection Methods for CVE-2025-22392

Indicators of Compromise

• Unusual or anomalous network traffic to Intel AMT management ports (16992/TCP for HTTP, 16993/TCP for HTTPS)
• Unexpected authentication attempts against AMT interfaces from unauthorized sources
• Abnormal patterns in AMT management logs indicating repeated or malformed requests
• Memory access violations or errors reported in firmware diagnostic logs

Detection Strategies

• Monitor network traffic for connections to Intel AMT management ports from unexpected sources or with unusual request patterns
• Implement network segmentation to isolate AMT management traffic and enable focused monitoring
• Review Intel AMT audit logs for suspicious administrative access patterns or failed authentication attempts
• Deploy network intrusion detection signatures targeting anomalous AMT protocol traffic

Monitoring Recommendations

• Enable comprehensive logging on Intel AMT interfaces and forward logs to a centralized SIEM platform
• Establish baseline behavior for AMT management traffic and alert on deviations
• Monitor for firmware update activities and validate all updates against Intel's official releases
• Implement alerting for any out-of-band management activity during non-maintenance windows

How to Mitigate CVE-2025-22392

Immediate Actions Required

• Review the Intel Security Advisory SA-01280 for detailed guidance and affected version information
• Inventory all systems with Intel AMT or Standard Manageability enabled to identify vulnerable deployments
• Apply firmware updates from Intel as soon as they become available for your platform
• Restrict network access to AMT management interfaces to authorized management networks only
• Audit and rotate privileged credentials used for AMT administration

Patch Information

Intel has released security guidance for this vulnerability through Intel Security Advisory SA-01280. System administrators should consult this advisory for specific firmware versions affected and obtain updated firmware from their system manufacturer or directly from Intel.

Firmware updates for Intel AMT are typically distributed through OEM update channels. Contact your hardware vendor for the appropriate update package for your specific system model.

Workarounds

• If firmware updates are not immediately available, consider disabling Intel AMT or Standard Manageability on systems where remote management is not essential
• Implement strict network segmentation to isolate AMT management traffic on a dedicated, secured management VLAN
• Apply firewall rules to restrict access to AMT ports (16992, 16993) to only authorized management stations
• Enable and enforce strong authentication mechanisms for AMT access, including complex passwords and certificate-based authentication where supported
• Consider using Intel AMT's built-in network isolation features to limit exposure until patching is complete
