CVE-2024-55407 is a vulnerability identified in the DeviceloControl function of the ITE IO Access driver version 1.0.0.0 developed by ITE Tech. Inc. This driver facilitates low-level hardware access via IOCTL (Input Output Control) requests. The vulnerability arises because the driver improperly restricts access to port read and write operations, allowing attackers with limited privileges (PR:L) to craft malicious IOCTL requests that perform arbitrary port I/O operations. This can lead to unauthorized reading from or writing to hardware ports, potentially compromising system confidentiality, integrity, and availability. The CVSS 3.1 base score of 7.8 reflects a high severity, with the attack vector being local (AV:L), requiring low privileges (PR:L), no user interaction (UI:N), and unchanged scope (S:U). The vulnerability is categorized under CWE-1284, which relates to improper access control for I/O ports. Although no exploits have been reported in the wild yet, the potential for attackers to manipulate hardware-level operations poses a significant risk. The lack of published patches means that affected systems remain vulnerable until vendor remediation is available. This vulnerability is particularly critical for environments where the ITE IO Access driver is deployed, often in embedded systems, industrial control, or specialized hardware platforms. Attackers exploiting this flaw could bypass security controls, manipulate hardware behavior, or cause system instability.

The impact of CVE-2024-55407 is substantial for organizations using hardware or software stacks that include the vulnerable ITE IO Access driver. Successful exploitation allows attackers to perform arbitrary port read and write operations, which can lead to unauthorized disclosure of sensitive information, corruption or manipulation of hardware states, and denial of service through hardware misconfiguration or disruption. This undermines the confidentiality, integrity, and availability of affected systems. Given the local attack vector and requirement for low privileges, attackers who have gained limited access to a system could escalate their control to a hardware manipulation level, potentially bypassing higher-level security mechanisms. This is especially critical in industrial, embedded, or critical infrastructure environments where hardware control is tightly linked to operational safety and security. The absence of known exploits in the wild provides a window for proactive defense, but the lack of patches increases risk. Organizations globally that rely on ITE Tech hardware components or drivers should consider this vulnerability a high priority for risk management and incident prevention.

To mitigate CVE-2024-55407 effectively, organizations should implement the following specific measures: 1) Restrict access to the ITE IO Access driver by enforcing strict permissions and limiting which users or processes can issue IOCTL requests to it. 2) Employ application whitelisting and endpoint protection solutions to monitor and block unauthorized attempts to interact with the driver at the IOCTL level. 3) Conduct thorough auditing and logging of IOCTL calls to detect anomalous or suspicious port read/write activities indicative of exploitation attempts. 4) Isolate systems running the vulnerable driver from untrusted users and networks to reduce the risk of local privilege exploitation. 5) Engage with ITE Tech or hardware vendors to obtain patches or updated driver versions as soon as they become available and plan for timely deployment. 6) In environments where patching is delayed, consider disabling or uninstalling the vulnerable driver if it is not essential to system operation. 7) Educate system administrators and security teams about the vulnerability specifics to enhance detection and response capabilities. These targeted actions go beyond generic advice by focusing on controlling driver access, monitoring low-level hardware interactions, and preparing for vendor remediation.
