Overview<\/strong><\/p>\n

CVE-2025-10541 is a critical security vulnerability discovered in iMonitor EAM, which potentially allows threat actors to escalate their privileges on the system. The flaw lies within the system service’s insecure update mechanism that can be manipulated to load and execute malicious files, resulting in system compromise or data leakage. Thus, it is of utmost importance for organizations using iMonitor EAM to apply the necessary patches or preventive measures.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-10541
\nSeverity: High (7.8 CVSS)

Product | Affected Versions<\/p>\n

iMonitor EAM | 9.6394<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit operates by abusing the insecure update mechanism of the ‘eamusbsrv64.exe’ system service that runs with NT AUTHORITY\\SYSTEM privileges. The service is designed to automatically load files placed in the C:\\sysupdate\\ directory during startup. However, because any local user can create and write to this directory, an attacker can place malicious DLLs or executables in it. Upon service restart, these malicious files are moved to the application\u2019s installation path and executed with SYSTEM privileges, leading to privilege escalation.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

While this flaw doesn’t involve web-based exploits, a conceptual example of how an attacker could potentially exploit this vulnerability might look like this:<\/p>\n

# Assume local user access\ncd C:\\sysupdate\\\n# Create malicious file\necho \"malicious code here\" > malicious.dll\n# Restart the service to trigger the exploit\nnet stop eamusbsrv64\nnet start eamusbsrv64<\/code><\/pre>\n
In this scenario, the attacker creates a malicious.dll file in the ‘sysupdate’ directory. Upon service restart, the malicious file is loaded and executed with SYSTEM privileges.<\/p>\n","protected":false},"excerpt":{"rendered":"
