CVE-2025-26615: Wegia Path Traversal Vulnerability

CVE-2025-26615 Overview

A Path Traversal vulnerability has been discovered in WeGIA, an open source Web Manager for Institutions with a focus on Portuguese language users. The vulnerability exists in the examples.php endpoint and could allow an attacker to gain unauthorized access to sensitive information stored in config.php. Since config.php contains database connection credentials and configuration details, successful exploitation could lead to direct database access and further compromise of the affected system.

Critical Impact

Attackers can exploit this path traversal vulnerability to read sensitive configuration files containing database credentials, potentially leading to complete database compromise and unauthorized data access.

Affected Products

• WeGIA Web Manager versions prior to 3.2.14
• WeGIA installations with exposed examples.php endpoint
• Systems running vulnerable WeGIA configurations

Technical Details for CVE-2025-26615

Vulnerability Analysis

This vulnerability is classified as CWE-22 (Improper Limitation of a Pathname to a Restricted Directory), commonly known as Path Traversal or Directory Traversal. The flaw resides in the examples.php endpoint of the WeGIA application, which fails to properly validate and sanitize user-supplied input used in file path operations.

When exploited, an attacker can manipulate file path parameters to traverse outside the intended directory structure and access arbitrary files on the server. The primary target identified is config.php, which typically contains sensitive database connection strings, credentials, and application secrets. Access to this configuration file could enable attackers to establish direct database connections, exfiltrate data, or escalate their attack further into the infrastructure.

The vulnerability requires no authentication and can be exploited remotely over the network, making it particularly dangerous for internet-facing WeGIA installations.

Root Cause

The root cause of this vulnerability is insufficient input validation and sanitization in the examples.php endpoint. The application fails to properly filter or block path traversal sequences such as ../ in user-supplied input before using it in file system operations. This allows attackers to escape the intended directory context and navigate to arbitrary locations on the file system where the web server has read permissions.

Attack Vector

The attack can be executed remotely over the network without requiring any prior authentication or user interaction. An attacker crafts a malicious HTTP request to the examples.php endpoint, including path traversal sequences designed to navigate to the config.php file. The vulnerability is network-accessible and has low attack complexity, meaning it can be exploited with minimal technical skill or specialized knowledge.

Successful exploitation results in high confidentiality impact through the disclosure of sensitive configuration data, though integrity and availability of the system remain unaffected directly by this vulnerability.

Detection Methods for CVE-2025-26615

Indicators of Compromise

• Unusual HTTP requests to examples.php containing path traversal sequences like ../, ..%2f, or ..%252f
• Web server logs showing access attempts to sensitive files such as config.php through the examples.php endpoint
• Unexpected database access patterns from unfamiliar IP addresses following potential configuration file exposure
• Access logs revealing repeated requests to examples.php with varying directory traversal payloads

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block path traversal patterns in HTTP requests
• Configure server-side logging to capture and alert on requests containing path traversal sequences
• Deploy file integrity monitoring on sensitive configuration files including config.php
• Utilize endpoint detection and response (EDR) solutions to identify anomalous file access patterns

Monitoring Recommendations

• Enable detailed access logging for the WeGIA application and review logs regularly for suspicious activity
• Set up alerts for HTTP requests containing encoded or unencoded path traversal sequences targeting WeGIA endpoints
• Monitor database connection logs for unauthorized access attempts using credentials that may have been exposed
• Implement security information and event management (SIEM) rules to correlate path traversal attempts with subsequent suspicious activities

How to Mitigate CVE-2025-26615

Immediate Actions Required

• Upgrade WeGIA to version 3.2.14 or later immediately, as this version addresses the vulnerability
• Restrict access to the examples.php endpoint if not required for production operations
• Rotate all database credentials stored in config.php as a precautionary measure
• Review access logs to determine if the vulnerability has been exploited prior to patching

Patch Information

The WeGIA development team has addressed this vulnerability in version 3.2.14. All users are strongly advised to upgrade to this version or later. For detailed information about the fix and the security advisory, refer to the GitHub Security Advisory GHSA-p5wx-pv8j-f96h.

Workarounds

• No official workarounds are available for this vulnerability according to the vendor advisory
• Consider temporarily disabling or restricting access to the examples.php endpoint via web server configuration until patching is complete
• Implement network-level access controls to limit exposure of the WeGIA application to trusted networks only
• Deploy a Web Application Firewall (WAF) with rules to block path traversal attempts as an interim protective measure
