Overview
CVE-2025-26155 details an Untrusted Search Path vulnerability affecting NCP Secure Enterprise Client version 13.18 and NCP Secure Entry Windows Client version 13.19. This vulnerability could allow a local attacker to execute arbitrary code with elevated privileges. It is crucial to understand the implications and take immediate action to mitigate this risk.
Technical Details
The vulnerability stems from the application’s reliance on the Windows search path when loading certain DLL files. If a malicious DLL file with the same name as one expected by the NCP client is placed in a directory that appears earlier in the search path than the legitimate location, the malicious DLL will be loaded instead. This allows an attacker to execute arbitrary code within the context of the NCP client process, potentially gaining system-level privileges.
CVSS Analysis
Currently, the National Vulnerability Database (NVD) has not assigned a CVSS score to CVE-2025-26155. However, given the potential for arbitrary code execution with elevated privileges, it is reasonable to assume that this vulnerability would receive a high severity score once officially assessed. We will update this post as soon as a CVSS score becomes available.
Possible Impact
A successful exploit of this vulnerability could have severe consequences, including:
- Arbitrary Code Execution: An attacker could execute any code on the system with the privileges of the NCP client process.
- System Compromise: This could lead to a complete compromise of the affected system.
- Data Theft: Sensitive data could be stolen by the attacker.
- Malware Installation: The attacker could install malware on the system.
- Lateral Movement: The attacker could use the compromised system to gain access to other systems on the network.
Mitigation and Patch Steps
The recommended mitigation steps are as follows:
- Upgrade: The primary mitigation is to upgrade to a patched version of NCP Secure Enterprise Client or NCP Secure Entry Windows Client that addresses this vulnerability. Check the NCP website for the latest versions and security advisories.
- Verify Software Origin: Always download software from trusted sources, such as the official NCP website.
- Principle of Least Privilege: Ensure that user accounts have only the necessary privileges to perform their tasks.
- Monitor System Activity: Implement monitoring solutions to detect suspicious activity, such as unexpected DLL loading or privilege escalation.
