CVE-2024-44570 identifies a critical code injection vulnerability in the RELY-PCIe product line, affecting versions 22.2.1 through 23.1.0. The vulnerability resides in the getParams function of the phpinf.php script, where insufficient input validation allows an attacker to inject and execute arbitrary code. This issue is categorized under CWE-77, which involves improper neutralization of special elements in commands, leading to command injection. The vulnerability can be exploited remotely over the network without requiring user interaction, though it does require low-level privileges (PR:L). The CVSS v3.1 base score of 8.8 reflects the high impact on confidentiality, integrity, and availability, as successful exploitation could lead to full system compromise. Despite no known exploits currently in the wild, the vulnerability poses a significant risk due to the ease of exploitation and the critical nature of the affected systems. RELY-PCIe is commonly used in environments requiring PCIe interface management, often in industrial, telecommunications, and embedded systems, making this vulnerability particularly concerning for critical infrastructure. The lack of available patches at the time of disclosure necessitates immediate risk mitigation through configuration changes, access restrictions, and monitoring until official fixes are released.

The impact of CVE-2024-44570 is substantial for organizations using RELY-PCIe versions 22.2.1 to 23.1.0. Successful exploitation allows attackers to execute arbitrary code remotely, potentially leading to full system compromise. This can result in unauthorized data access or modification, disruption of critical services, and potential lateral movement within networks. The vulnerability affects confidentiality by exposing sensitive data, integrity by allowing unauthorized changes, and availability by enabling denial-of-service conditions. Given RELY-PCIe's deployment in industrial and embedded systems, exploitation could disrupt operational technology environments, causing physical and economic damage. The requirement for low privileges lowers the barrier for attackers, increasing the likelihood of exploitation if systems are exposed. Organizations without timely mitigation may face significant operational risks, regulatory penalties, and reputational damage.

To mitigate CVE-2024-44570, organizations should immediately restrict network access to the affected RELY-PCIe devices, limiting exposure to trusted management networks only. Implement strict access controls and monitor for unusual activity related to the phpinf.php script and the getParams function. Employ web application firewalls (WAFs) with custom rules to detect and block command injection patterns targeting this vulnerability. Until official patches are released, consider disabling or restricting the functionality of the getParams endpoint if feasible. Conduct thorough input validation and sanitization on all user-supplied data interacting with RELY-PCIe interfaces. Regularly audit and update privilege assignments to ensure minimal necessary access. Additionally, maintain comprehensive logging and alerting to detect potential exploitation attempts. Prepare for rapid deployment of official patches once available and test updates in controlled environments before production rollout.
