CVE-2025-10540 identifies a vulnerability in iMonitor Software Inc.'s iMonitor EAM version 9.63.94, where communications between the EAM client agent and server, as well as between the EAM monitor management software and the server, are transmitted in plaintext without any encryption or authentication mechanisms. This cleartext transmission exposes sensitive information such as user credentials, keylogger data, and personally identifiable information (PII) to interception by attackers with network access. Furthermore, the lack of integrity protection allows attackers to tamper with the communication, enabling them to issue arbitrary commands to client agents, potentially leading to unauthorized control over monitored endpoints. The vulnerability is exploitable remotely over the network without requiring any user interaction or prior authentication, increasing the attack surface. Although no exploits have been observed in the wild yet, the vulnerability represents a significant risk, especially in environments where iMonitor EAM is used to monitor sensitive or critical systems. The CVSS v3.1 base score of 6.5 reflects a medium severity rating, primarily due to the confidentiality and integrity impacts, the ease of network-based exploitation, and the absence of availability impact. The vulnerability falls under CWE-319, which concerns cleartext transmission of sensitive information, a common and critical security weakness. The lack of vendor patches or mitigations at the time of publication further elevates the risk. Organizations relying on iMonitor EAM should prioritize securing communication channels and restricting network access to mitigate potential exploitation.

For European organizations, this vulnerability poses a risk of unauthorized disclosure of sensitive data including credentials and PII, which can lead to identity theft, espionage, or further compromise of internal systems. The ability for attackers to tamper with traffic and issue arbitrary commands to client agents could result in unauthorized control over monitored endpoints, potentially disrupting business operations or enabling lateral movement within networks. Sectors such as finance, healthcare, government, and critical infrastructure that rely on iMonitor EAM for endpoint monitoring are particularly at risk. Data protection regulations like GDPR increase the stakes, as breaches involving PII could lead to significant fines and reputational damage. The vulnerability's exploitation could also undermine trust in security monitoring solutions, complicating incident detection and response. Since the vulnerability requires network access but no authentication, attackers who gain access to internal or poorly segmented networks could exploit it, emphasizing the need for robust network security controls. The absence of known exploits in the wild provides a window for proactive mitigation before widespread attacks occur.

1. Immediately restrict network access to iMonitor EAM servers and clients by implementing strict firewall rules and network segmentation to limit exposure to trusted hosts only. 2. Deploy VPNs or encrypted tunnels (e.g., TLS/SSL) to secure communications between EAM client agents, management software, and servers, compensating for the lack of native encryption. 3. Monitor network traffic for unusual patterns or unauthorized command issuance to client agents, using intrusion detection/prevention systems (IDS/IPS) tailored to detect anomalies in EAM communications. 4. Conduct a thorough inventory of all iMonitor EAM deployments and upgrade to patched versions as soon as they become available from the vendor. 5. Implement multi-factor authentication and strong access controls on management consoles to reduce risk if command injection attempts occur. 6. Educate network administrators and security teams about the vulnerability and the importance of securing internal network segments where EAM components operate. 7. Regularly audit logs and endpoint activity for signs of compromise or unauthorized access related to iMonitor EAM. 8. Engage with the vendor for updates on patches or official mitigations and participate in threat intelligence sharing communities to stay informed about emerging exploits.
