CVE-2025-10542 is a critical security vulnerability identified in iMonitor Software Inc.'s iMonitor EAM product, specifically version 9.63.94. The root cause is the presence of default administrative credentials that are not only preset but also displayed within the management client's connection dialog. This design flaw allows any remote attacker to authenticate to the EAM server without prior privileges or user interaction, provided the default credentials remain unchanged. Once authenticated, the attacker gains full administrative control over the EAM server, enabling them to manipulate all monitored agents and access sensitive telemetry data, including keylogger outputs. This level of access compromises confidentiality, integrity, and availability of the monitored systems. The vulnerability is rated with a CVSS v3.1 score of 9.8, reflecting its critical nature due to network attack vector, no required privileges or user interaction, and complete system compromise potential. Although no exploits are currently known in the wild, the simplicity of exploitation and the severity of impact make this a high-risk vulnerability. The vulnerability is tracked under CWE-1392, which relates to the use of default credentials, a common but severe security oversight. The lack of available patches at the time of publication increases the urgency for organizations to implement compensating controls.

For European organizations, the impact of CVE-2025-10542 is substantial. Organizations relying on iMonitor EAM for endpoint monitoring and management could face full compromise of their monitoring infrastructure if default credentials are not changed. Attackers gaining control can exfiltrate sensitive telemetry data, including keystrokes, potentially exposing confidential information and intellectual property. The ability to issue arbitrary commands to connected clients can lead to widespread disruption, data manipulation, or further lateral movement within networks. Critical sectors such as government agencies, financial institutions, healthcare providers, and energy companies that use iMonitor EAM for security monitoring are particularly at risk. The breach of telemetry data can undermine trust in security operations and lead to regulatory penalties under GDPR due to data exposure. Additionally, the availability of the monitoring system can be disrupted, impairing incident detection and response capabilities. The lack of required privileges or user interaction lowers the barrier for attackers, increasing the likelihood of exploitation in targeted or opportunistic attacks.

1. Immediately change all default administrative credentials on iMonitor EAM servers to strong, unique passwords. 2. Restrict network access to the iMonitor EAM management interface using network segmentation, firewalls, or VPNs to limit exposure to trusted administrators only. 3. Implement multi-factor authentication (MFA) if supported by the product or via external access controls to add an additional layer of security. 4. Monitor logs and network traffic for unusual authentication attempts or access patterns to detect potential exploitation attempts early. 5. Conduct an audit of all deployed iMonitor EAM instances to ensure no default credentials remain in use. 6. Engage with the vendor for patches or updates addressing this vulnerability and apply them promptly once available. 7. Educate administrators and users about the risks of default credentials and enforce credential management policies. 8. Consider deploying endpoint detection and response (EDR) tools to detect anomalous behavior resulting from potential compromise of monitored clients.
