Overview
In the rapidly evolving field of cybersecurity, new vulnerabilities are continually being discovered and exploited. One recent vulnerability, identified as CVE-2025-2521, has been detected in Honeywell Experion PKS and OneWireless WDM. These systems are widely used in industrial control, exposing a broad range of industries to potential attacks. The vulnerability lies in an overread buffer in the Control Data Access (CDA) component, which could lead to remote code execution by a malicious actor.
This vulnerability is particularly concerning due to its severe impact and the wide range of affected products. The potential for system compromise or data leakage is a significant threat to the security and integrity of operations in affected industries.

Product | Affected Versions
Honeywell Experion PKS | 520.1 through 520.2 TCU9 and 530 through 530 TCU3
OneWireless WDM | 322.1 through 322.4 and 330.1 through 330.3
How the Exploit Works
The vulnerability in question exists due to inadequate buffer size validation in the CDA component of the affected systems. An attacker could exploit this by sending specially crafted packets that would cause an overread of the buffer. This could potentially lead to remote code execution, allowing an attacker to execute arbitrary code on the affected system.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited. This is a pseudocode representation of a malicious packet that might trigger the buffer overread:
# Malicious Payload
malicious_payload = {"buffer": "OVERFLOW"}
# Send the malicious payload
send_packet("target_ip_address", "target_port", malicious_payload)Please note that this is a simplified representation and actual exploit code would likely be more complex.
