Executive Summary

This is a path traversal vulnerability in Zr.Admin.NET where authenticated users can read arbitrary server files by manipulating the path parameter in the /common/DownloadFile endpoint. Attackers can use absolute paths or directory traversal sequences like ../ to access sensitive files such as appsettings.json. If the appsettings file contains the JwtSettings SecretKey, attackers can forge administrator tokens.

Detection Guidance

To detect this vulnerability, check if your Zr.Admin.NET application has the affected endpoints /common/DownloadFile and /BaseController.cs with the path traversal flaw. Monitor for unauthorized file access attempts or unusual file download requests containing ../ or absolute paths.

Impact Analysis

An attacker could read sensitive server files, including configuration files with secrets like the JwtSettings SecretKey. This could lead to full system compromise, unauthorized access, or privilege escalation to administrator level. The high CVSS score of 8.7 indicates significant risk.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection requirements and HIPAA's security rules for protected health information. Organizations using this software may face compliance violations, legal penalties, and reputational damage.

Mitigation Strategies

Immediately update Zr.Admin.NET to a version beyond commit eb9228a. Restrict access to the /common/DownloadFile endpoint to authorized users only. Review server logs for suspicious file access patterns and revoke any compromised administrator tokens.
