CVE-2021-37292 Scanner

KevinLAB BEMS (Building Energy Management System) is designed for monitoring and managing energy consumption within large buildings. It is extensively used by facility managers, building owners, and engineers to optimize energy efficiency and reduce operational costs. The system integrates various energy control and monitoring devices to provide real-time data and analytics. Its purpose is to enhance sustainable energy usage and improve resource management within commercial and industrial facilities. This software is applicable for smart buildings and can be scaled to manage multiple facilities, offering centralized control and reporting.

The vulnerability identified in KevinLAB BEMS pertains to an undocumented backdoor account within the system. This backdoor compromises security as it allows unauthorized users to gain administrative access. By exploiting this vulnerability, attackers can bypass standard authentication mechanisms and manipulate system operations. The backdoor is not listed within user settings, making it invisible during standard administrative checks. Additionally, the associated privileges grant attackers extensive control over system functionalities remotely. This inherent vulnerability poses significant risks to the integrity and availability of the managed building systems.

Technically, the vulnerability exists due to an undocumented backdoor account that utilizes specific credentials. This account is embedded within the system and is not disclosed to end-users, hence not modifiable through conventional means. Attackers can exploit the backdoor by sending specific login requests to gain administrative privileges. The endpoint targeted typically includes login forms where malicious actors insert predefined credentials to achieve unauthorized access. The backdoor remains hidden from view within user interfaces, making detection difficult without specialized scanning. It operates with an undocumented privilege level that exceeds typical admin controls.

The potential effects of exploiting this backdoor include complete system takeover by malicious entities. Attackers may disrupt building energy management controls, leading to substantial operational inefficiencies. Unauthorized access provides an opportunity for data manipulation or exfiltration, causing privacy concerns. The integrity of energy management outputs can be compromised, affecting decision-making processes for building optimization. Moreover, full control access raises the risk of sabotage, potentially damaging equipment or altering predefined energy schedules. These repercussions necessitate immediate attention to mitigate impact and secure the infrastructure.
