CVE-2025-22617

6.1 MEDIUM

📋 TL;DR

This CVE describes a reflected cross-site scripting (XSS) vulnerability in WeGIA's editar_socio.php endpoint where the 'socio' parameter is not properly sanitized. Attackers can inject malicious scripts that execute in victims' browsers when they visit crafted URLs. All WeGIA users running versions before 3.2.7 are affected.

💻 Affected Systems

Products:
  • WeGIA
Versions: All versions before 3.2.7
Operating Systems: Any OS running WeGIA
Default Config Vulnerable: ⚠️ Yes
Notes: The vulnerability exists in the default installation when the editar_socio.php endpoint is accessible.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers could steal session cookies, perform actions as authenticated users, redirect to malicious sites, or install malware via drive-by downloads.

🟠

Likely Case

Session hijacking leading to unauthorized access, credential theft, or defacement of the application interface.

🟢

If Mitigated

With proper input validation and output encoding, the malicious scripts would be rendered harmless as text rather than executed code.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Reflected XSS vulnerabilities are commonly exploited and require minimal technical skill. The advisory confirms the vulnerability exists but no public exploit code is mentioned.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 3.2.7

Vendor Advisory: https://github.com/LabRedesCefetRJ/WeGIA/security/advisories/GHSA-8cp5-vr69-h8xx

Restart Required: No

Instructions:

1. Backup your current WeGIA installation and database. 2. Download WeGIA version 3.2.7 or later from the official repository. 3. Replace the existing files with the updated version. 4. Verify the editar_socio.php file contains proper input validation/sanitization.

🔧 Temporary Workarounds

Web Application Firewall (WAF) Rules

all

Implement WAF rules to block malicious script patterns in the 'socio' parameter

Input Validation Filter

all

Add server-side validation to reject or sanitize suspicious characters in the socio parameter

🧯 If You Can't Patch

  • Implement a Web Application Firewall (WAF) with XSS protection rules
  • Restrict access to the editar_socio.php endpoint to trusted users only

🔍 How to Verify

Check if Vulnerable:

Test the editar_socio.php endpoint with a harmless XSS payload like <script>alert('test')</script> in the socio parameter. If the script executes, the system is vulnerable.

Check Version:

Check the WeGIA version in the application interface or review the application files for version indicators.

Verify Fix Applied:

After patching, repeat the same test with the XSS payload. The script should not execute and should be properly encoded or rejected.

📡 Detection & Monitoring

Log Indicators:

  • Unusual GET/POST requests to editar_socio.php with script tags or JavaScript in parameters
  • Multiple failed attempts with suspicious parameter values

Network Indicators:

  • HTTP requests containing <script> tags or JavaScript functions in URL parameters
  • Traffic patterns showing users being redirected after visiting specific URLs

SIEM Query:

source="web_server_logs" AND uri="*editar_socio.php*" AND (param="*<script>*" OR param="*javascript:*" OR param="*onload=*" OR param="*onerror=*")
