CVE-2023-38655

CVE-2023-38655 describes a vulnerability in the firmware of Intel(R) Active Management Technology (AMT) and Intel(R) Standard Manageability. The root cause is improper buffer restrictions, which can be triggered when a privileged user sends crafted network packets to the management interface.

Attack

Vector and Prerequisites To exploit this vulnerability, an attacker must already have privileged access to the affected system's management network, or be able to authenticate as a privileged user on that interface. The attack is carried out over the network, sending specially crafted requests that trigger the buffer-handling flaw.

Impact

A successful exploit could lead to a denial of service (DoS) condition, potentially making the management features unavailable. This could prevent remote management and monitoring, interrupting critical administrative functions on affected platforms.

Mitigation

Intel has released firmware updates to address this issue, as detailed in the advisory INTEL-SA-00999 [1]. Users are advised to update their firmware to the latest version provided by their system manufacturer to mitigate the risk.
