Impact Analysis

This vulnerability can have a significant impact because it allows an unprivileged user on the affected system to gain SYSTEM-level privileges. SYSTEM privileges are the highest level of access on a Windows system, enabling the attacker to execute arbitrary code, modify system settings, access sensitive data, install malware, or disrupt system operations.

Detection Guidance

The vulnerability CVE-2026-35099 affects the LsiAgent.exe loopback component of the Lakeside SysTrack Agent and involves a race condition that allows local privilege escalation. Detection would involve identifying if vulnerable versions of the SysTrack agent (versions before 11.2.1.28, 11.3.0.38, 11.4.0.24, and 11.5.0.15) are running on the system.

To detect the presence of the vulnerable SysTrack agent, you can check the installed version of the agent on your system. For example, on Windows systems, you might use commands like:

• wmic product where "name like '%SysTrack Agent%'" get Name, Version
• Get-Service -Name LsiAgent | Select-Object Status, Name (in PowerShell to check if the service is running)

Additionally, monitoring for unusual crashes or application errors related to LsiAgent.exe, especially those triggered by malformed UDP packets, could indicate exploitation attempts.

Network monitoring tools could be used to detect malformed UDP packets targeting the SysTrack agent, but specific signatures or commands for this are not provided in the available resources.

Ultimately, the best detection method is to verify the version of the SysTrack agent and ensure it is updated to one of the fixed versions: 11.2.1.28, 11.3.0.38, 11.4.0.24, or 11.5.0.15.
