The cybersecurity landscape is continually evolving, bringing forth new threats and vulnerabilities. Recently, a critical remote path traversal vulnerability, identified as CVE-2025-10766, has surfaced in SeriaWei ZKEACMS versions up to 4.3. This vulnerability poses a significant risk to server security for system administrators and hosting providers.

Overview of the Vulnerability

The CVE-2025-10766 vulnerability targets the Download function in the EventViewerController.cs file. By manipulating the argument ID, attackers can exploit this weakness to perform path traversal attacks. This vulnerability allows unauthorized access to sensitive files and could result in the disclosure of confidential information.

Importance for Server Admins and Hosting Providers

This vulnerability is especially critical for system administrators and hosting providers. Exploitation could lead to unauthorized access to not just application files but potentially the entire server. Thus, it is vital to understand the risks involved and the necessary mitigations.

Mitigation Steps

To protect your Linux servers and the applications hosted on them, consider the following proactive security measures:

• Update SeriaWei ZKEACMS to the latest version to incorporate security patches provided by the vendor.
• Restrict access to the EventViewerController.cs file to minimize potential exploitation.
• Sanitize all user inputs for the ID parameter to prevent unauthorized access attempts.
• Implement a web application firewall (WAF) to provide additional layers of security against attacks.
