An unauthenticated attacker can send a specially crafted update file to the device that can overflow a buffer. This vulnerability impacts products based on HID Mercury Intelligent Controllers LP1501, LP1502, LP2500, LP4502, and EP4502 which contain firmware versions prior to 1.302 for the LP series and 1.296 for the EP series. The overflowed data can allow the attacker to manipulate the “normal” code execution to that of their choosing. An attacker with this level of access on the device can monitor all communications sent to and from this device, modify onboard relays, change configuration files, or cause the device to become unstable.
Source: NIST NVD / MITRE CVE Database
The vulnerability allows an unauthenticated attacker to send a specially crafted update file to the device, causing a buffer overflow. This can lead to remote code execution, allowing the attacker to monitor communications, modify onboard relays, change configuration files, or destabilize the device.

Implement network segmentation and access controls to restrict communication to the affected controllers only from trusted sources. Regularly monitor network traffic for suspicious activity.
No reliable network detection signature exists for this vulnerability class — apply the compensating controls above and the vendor patch. SAGE only publishes a network rule when a concrete on-the-wire signature can be grounded in the advisory.
This CVE violates CIP-007-R2 as it allows unauthorized access to the control system, potentially leading to the compromise of critical assets and operations.
This CVE maps to SR 7.6 because it involves a vulnerability that can be exploited remotely, leading to unauthorized control of the device and potential disruption of industrial processes.
Virtual patch generated by CITED Relevance SAGE. Validate in isolated environment before production deployment. Compensating control only - does not replace vendor patch.
