CVE-2025-3920 in CMMS
Summary
by MITRE • 07/07/2025
A vulnerability was identified in SUR-FBD CMMS where hard-coded credentials were found within a compiled DLL file. These credentials correspond to a built-in administrative account of the software. An attacker with local access to the system or the application's installation directory could extract these credentials, potentially leading to a complete compromise of the application's administrative functions. This issue was fixed in version 2025.03.27 of the SUR-FBD CMMS software.

The vulnerability described in CVE-2025-3920 represents a critical security flaw within the SUR-FBD CMMS software ecosystem, specifically manifesting as hard-coded credentials embedded within a compiled dynamic link library file. This type of vulnerability falls under the category of insecure credential storage practices and directly violates fundamental security principles regarding authentication and access control mechanisms. The presence of administrative credentials within compiled binary code creates a persistent attack surface that remains accessible to any entity capable of examining the application's installation directory or executing code locally on the target system.
The technical implementation of this flaw involves the inclusion of hardcoded authentication credentials within the DLL file structure, which serves as an executable component of the larger CMMS application. This approach fundamentally undermines the security model of the system, as it eliminates the possibility of dynamic credential management and creates a single point of failure that can be exploited by attackers with minimal technical sophistication. The vulnerability's exploitation requires only local system access or the ability to examine the application's installation directory, making it particularly dangerous in environments where physical or network access controls may be insufficient.
From an operational impact perspective, this vulnerability creates a severe risk of complete system compromise, as the hard-coded administrative credentials provide attackers with elevated privileges that bypass normal authentication mechanisms. The compromised administrative account can be used to manipulate system configurations, access sensitive data, modify user permissions, and potentially establish persistent access through the administrative interface. This represents a direct violation of the principle of least privilege and creates opportunities for attackers to escalate their access within the CMMS environment, potentially leading to broader system infiltration and data exfiltration.
The remediation for this vulnerability required the development team to implement proper credential management practices and remove the hardcoded credentials from the compiled application binaries. This fix aligns with established security best practices and standards including those outlined in the CWE catalog under CWE-798, which specifically addresses the use of hard-coded credentials, and reflects the principles of the MITRE ATT&CK framework's credential access tactics where adversaries seek to obtain credentials through various means including the exploitation of hardcoded values. Organizations implementing SUR-FBD CMMS should prioritize immediate deployment of version 2025.03.27 to address this vulnerability and should conduct thorough security assessments of their existing installations to identify any potential compromise. The fix demonstrates the importance of proper software development lifecycle practices including secure coding guidelines and regular security audits to prevent such vulnerabilities from being introduced into production systems.
