CVE-2025-1729: TrackPoint Quick Menu DLL Hijacking Flaw

CVE-2025-1729 Overview

A DLL hijacking vulnerability has been identified in Lenovo TrackPoint Quick Menu software that could allow a local attacker to escalate privileges under certain conditions. This type of vulnerability occurs when an application loads a dynamic-link library (DLL) from an insecure location, enabling an attacker to substitute a malicious DLL that executes with the privileges of the vulnerable application.

Critical Impact

Local attackers with access to the system could exploit this vulnerability to gain elevated privileges, potentially compromising system integrity and confidentiality.

Affected Products

Technical Details for CVE-2025-1729

Vulnerability Analysis

This vulnerability is classified as CWE-427 (Uncontrolled Search Path Element), which describes a condition where an application searches for critical resources using an attacker-controllable search path. In the context of DLL hijacking, the TrackPoint Quick Menu software appears to load one or more DLLs from directories that can be manipulated by a low-privileged user.

When the vulnerable application executes, it searches for required DLLs in a predictable order. If an attacker can place a malicious DLL earlier in the search path than the legitimate library, the application will load and execute the attacker's code. This is particularly dangerous when the application runs with elevated privileges, as the malicious code inherits those same privileges.

Root Cause

The root cause of this vulnerability stems from improper DLL loading practices in the TrackPoint Quick Menu software. The application likely uses insecure methods to locate and load dynamic libraries, such as:

• Loading DLLs from the current working directory
• Using relative paths instead of fully qualified paths
• Failing to validate the integrity or location of loaded libraries
• Not implementing proper DLL search order hardening

Attack Vector

The attack requires local access to the system, making it a privilege escalation vector rather than a remote exploitation scenario. An attacker would need to:

1. Identify the vulnerable DLL loading behavior in TrackPoint Quick Menu
2. Determine which DLLs are loaded and from which locations
3. Place a malicious DLL in a location that precedes the legitimate DLL in the search path
4. Trigger the application to load the malicious library

The vulnerability mechanism involves DLL search order hijacking. When an application calls LoadLibrary() or LoadLibraryEx() without specifying an absolute path, Windows searches for the DLL in a defined sequence of directories. If the application's working directory or another user-writable location is searched before the system directories, an attacker can plant a malicious DLL there. The malicious DLL is then loaded and executed with the privileges of the parent process. For technical details, see the Lenovo Security Advisory LEN-189489.

Detection Methods for CVE-2025-1729

Indicators of Compromise

• Unexpected DLL files appearing in TrackPoint Quick Menu installation directories or working directories
• DLL files with names matching known TrackPoint dependencies located in unusual paths
• Process execution anomalies where TrackPoint Quick Menu spawns unexpected child processes
• Unauthorized privilege changes associated with TrackPoint-related processes

Detection Strategies

• Monitor for DLL loading events from non-standard directories using Windows Event Tracing or Sysmon
• Implement application whitelisting to detect unauthorized DLL loads
• Use endpoint detection and response (EDR) solutions to identify suspicious DLL sideloading behavior
• Audit file creation events in directories associated with TrackPoint Quick Menu

Monitoring Recommendations

• Enable Sysmon Event ID 7 (Image Loaded) to track DLL loading activities
• Configure alerts for DLL loads from user-writable directories by elevated processes
• Monitor for changes to TrackPoint Quick Menu installation directories
• Implement integrity monitoring for legitimate DLL files associated with the application

How to Mitigate CVE-2025-1729

Immediate Actions Required

• Review and apply the latest updates from Lenovo for TrackPoint Quick Menu software
• Restrict write access to directories where TrackPoint Quick Menu searches for DLLs
• Audit systems for any unauthorized DLL files in TrackPoint-related directories
• Consider temporarily disabling TrackPoint Quick Menu if elevated privilege functionality is not required

Patch Information

Lenovo has published a security advisory addressing this vulnerability. System administrators should consult the Lenovo Security Advisory LEN-189489 for specific patch information and updated software versions.

Workarounds

• Implement application control policies to prevent execution of unsigned DLLs
• Configure Windows SafeDllSearchMode to prioritize system directories in the DLL search order
• Use software restriction policies to limit DLL loading to trusted paths
• Remove unnecessary write permissions from application directories

# Windows SafeDllSearchMode registry configuration
# Run as Administrator to enable SafeDllSearchMode
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager" /v SafeDllSearchMode /t REG_DWORD /d 1 /f
