A vulnerability has been identified in APOGEE PXC+TALON TC Series (BACnet) (All versions). Affected devices start sending unsolicited BACnet broadcast messages after processing a specific BACnet createObject request. This could allow an attacker residing in the same BACnet network to send a specially crafted message that results in a partial denial of service condition of the targeted device, and potentially reduce the availability of BACnet network. A power cycle is required to restore the device's normal operation.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 4.7, indicating it requires adjacent network access with relatively low complexity without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts and limited availability for affected systems.
Reported in 2025, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For affected software, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
