CVE-2024-44610 identifies a command injection vulnerability in the PCAN-Ethernet Gateway FD (versions before 1.3.0) and PCAN-Ethernet Gateway (versions before 2.11.0). The vulnerability arises from improper handling of shell metacharacters in the Software Update functionality implemented in processing.php. Specifically, the update process fails to sanitize input, allowing an attacker with high privileges to inject arbitrary shell commands. This vulnerability is classified under CWE-77 (Improper Neutralization of Special Elements used in a Command). The CVSS v3.1 base score is 5.6, reflecting a medium severity level. The attack vector is local (AV:L), requiring low attack complexity (AC:L) but high privileges (PR:H), with no user interaction (UI:N). The scope is unchanged (S:U), and the impact is high on confidentiality (C:H), low on integrity (I:L), and low on availability (A:L). Although no known exploits are reported in the wild, the vulnerability could allow an attacker to execute arbitrary commands on the device, potentially leading to unauthorized data access or limited disruption of device functionality. The affected devices are specialized industrial communication gateways used to connect CAN networks to Ethernet, commonly found in automotive and industrial automation environments. Due to the nature of the vulnerability, exploitation requires an attacker to have elevated privileges on the device, limiting remote exploitation potential but increasing risk if internal systems are compromised. No official patches or updates are currently linked, so users should monitor vendor advisories closely.

The vulnerability could lead to unauthorized command execution on affected PCAN-Ethernet Gateway devices, compromising confidentiality by exposing sensitive data transmitted or stored on the device. Integrity impact is low but could allow limited unauthorized changes to device configuration or software update processes. Availability impact is also low but may cause partial disruption of gateway functionality if exploited. Organizations relying on these gateways for critical industrial or automotive network communications could experience operational disruptions or data breaches if attackers gain elevated access. Since exploitation requires high privileges and local access, the threat is more significant in environments where internal network security is weak or where attackers have already gained foothold. The lack of known exploits reduces immediate risk but does not eliminate the potential for future attacks. Overall, the vulnerability poses a moderate risk to organizations operating these devices, particularly in sectors where network integrity and data confidentiality are paramount.

Organizations should implement strict access controls to limit who can access the Software Update interface on PCAN-Ethernet Gateway devices, ensuring only trusted administrators have high privilege accounts. Network segmentation should isolate these devices from untrusted networks to reduce the risk of local privilege escalation leading to exploitation. Monitoring and logging of update processes and command executions on the gateway devices can help detect suspicious activity early. Until official patches are released, consider disabling remote update functionality if feasible or applying compensating controls such as application-layer firewalls to restrict access. Regularly check the vendor’s security advisories for updates or patches addressing this vulnerability and apply them promptly. Conduct internal audits to verify that no unauthorized commands or changes have been made to the devices. Additionally, enforce strong authentication mechanisms and keep device firmware and management software up to date to reduce the attack surface.
