CVE-2025-22392 is a medium-severity vulnerability identified in the firmware of Intel(R) Active Management Technology (AMT) and Intel(R) Standard Manageability. The flaw is an out-of-bounds read condition that can be triggered by a privileged user, potentially leading to information disclosure through network access. Intel AMT and Standard Manageability are remote management technologies embedded in many Intel chipsets, enabling IT administrators to remotely monitor, maintain, and repair systems even when the operating system is down or the device is powered off. The vulnerability arises from improper bounds checking in the firmware, which allows a privileged user to read memory outside the intended buffer limits. This can expose sensitive information residing in adjacent memory areas. The attack vector is network-based, requiring the attacker to have high privileges on the targeted system, but no user interaction is necessary. The CVSS v4.0 base score is 5.9, reflecting a medium severity level, with the attack complexity rated as high and privileges required as high. The vulnerability does not impact integrity or availability but compromises confidentiality by enabling unauthorized information disclosure. No known exploits are reported in the wild as of the publication date. The affected versions are not explicitly listed here but are referenced in Intel advisories. Since Intel AMT is widely deployed in enterprise environments for out-of-band management, this vulnerability could be leveraged by malicious insiders or attackers who have already gained privileged access to extract sensitive data remotely via the network interface exposed by AMT firmware. Given the firmware nature, patching typically requires firmware updates from device manufacturers or Intel, which can be complex and slow to deploy across large fleets of managed devices.

For European organizations, the impact of CVE-2025-22392 can be significant, especially for enterprises relying heavily on Intel AMT for remote management of their IT infrastructure. Information disclosure could lead to leakage of sensitive configuration data, credentials, or other confidential information stored in memory buffers. This could facilitate further attacks such as lateral movement, privilege escalation, or targeted espionage. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, may face compliance risks if sensitive data is exposed. Moreover, the network-accessible nature of the vulnerability means that attackers with privileged access could exploit it remotely, increasing the attack surface. The requirement for high privileges limits exploitation to insiders or attackers who have already compromised systems, but the potential for stealthy data exfiltration remains a concern. The complexity of patching firmware and the prevalence of Intel AMT in corporate laptops and desktops means that remediation may be slow, prolonging exposure. Additionally, the vulnerability could be leveraged in supply chain attacks or targeted campaigns against critical infrastructure operators in Europe, where Intel AMT is commonly used for remote device management.

To mitigate CVE-2025-22392, European organizations should take a multi-layered approach: 1) Inventory and identify all systems using Intel AMT and Standard Manageability firmware to understand the scope of exposure. 2) Apply firmware updates and patches provided by Intel or device manufacturers as soon as they become available, prioritizing critical and high-value assets. 3) Restrict network access to Intel AMT interfaces by implementing strict network segmentation and firewall rules, allowing only trusted management stations to communicate with AMT-enabled devices. 4) Enforce strong access controls and monitoring on privileged accounts that can interact with AMT firmware to prevent unauthorized use. 5) Disable Intel AMT or Standard Manageability features on devices where remote management is not required to reduce the attack surface. 6) Employ network intrusion detection systems (NIDS) and anomaly detection to identify unusual AMT-related network activity that could indicate exploitation attempts. 7) Conduct regular security audits and penetration testing focused on firmware and out-of-band management interfaces. 8) Educate IT staff about the risks associated with AMT vulnerabilities and the importance of timely patching and access control. These measures, combined, will reduce the risk of exploitation and limit potential information disclosure.
