CVE-2025-10542 is a vulnerability identified in iMonitor Software Inc.'s iMonitor EAM version 9.63.94. The core issue is the presence of default administrative credentials that are shipped with the product and are also displayed within the management client's connection dialog. This design flaw means that if the administrator does not proactively change these default credentials, a remote attacker can authenticate to the EAM server without any prior knowledge or complex exploitation techniques. Once authenticated, the attacker gains full control over all monitored agents and the data they collect. This includes access to highly sensitive telemetry data, such as keylogger outputs, which can expose confidential user inputs and activities. Additionally, the attacker can issue arbitrary commands to all connected clients, potentially manipulating or disrupting their operations. The vulnerability is categorized under CWE-1392, which relates to the use of default credentials, a common and critical security weakness. Although no CVSS score has been assigned yet, the vulnerability's characteristics indicate a significant risk due to the ease of exploitation and the breadth of control it grants. There are no known exploits in the wild at the time of publication, and no patches have been released, which means organizations must rely on immediate configuration changes to mitigate the risk.

For European organizations, the impact of this vulnerability can be severe. iMonitor EAM is used for endpoint activity monitoring and management, often in environments requiring strict oversight, such as government agencies, financial institutions, and critical infrastructure sectors. Unauthorized access through default credentials could lead to the exposure of sensitive telemetry data, including keystrokes, which may contain passwords, confidential communications, or proprietary information. This compromises confidentiality and privacy, potentially violating GDPR and other data protection regulations. Moreover, the ability to issue arbitrary commands to connected clients can disrupt business operations, cause data integrity issues, or facilitate lateral movement within networks, escalating the threat to availability and integrity. The risk is amplified in sectors where endpoint monitoring is critical for compliance and security posture, making this vulnerability a significant concern for European enterprises and public sector organizations.

To mitigate this vulnerability, European organizations using iMonitor EAM 9.63.94 should immediately perform the following actions: 1) Change the default administrative credentials to strong, unique passwords immediately upon installation or before deployment. 2) Audit existing deployments to verify that no systems are still using default credentials. 3) Restrict network access to the EAM server management interface by implementing network segmentation and firewall rules, limiting access to trusted administrative hosts only. 4) Enable multi-factor authentication (MFA) for administrative access if supported by the product or through external access control mechanisms. 5) Monitor logs and network traffic for unusual authentication attempts or commands issued to monitored clients. 6) Engage with iMonitor Software Inc. for updates or patches addressing this vulnerability and plan for timely application once available. 7) Educate administrators and users about the risks of default credentials and enforce policies to avoid such configurations in the future.
