CVE-2025-30363
📋 TL;DR
A stored Cross-Site Scripting (XSS) vulnerability in WeGIA web management software allows attackers to inject malicious scripts that are permanently stored on the server and executed in users' browsers when they view compromised pages. This affects all users of WeGIA versions prior to 3.2.6, potentially leading to session hijacking, data theft, or unauthorized actions.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, take over administrative accounts, deface the website, or redirect users to malicious sites, potentially compromising the entire charitable institution's operations.
Likely Case
Attackers inject malicious scripts to steal user session cookies, perform actions on behalf of authenticated users, or display phishing content to visitors.
If Mitigated
With proper input validation and output encoding, the risk is reduced to minimal, though the vulnerability still exists in the codebase.
🎯 Exploit Status
Stored XSS typically requires some level of user interaction or access to input fields, but exploitation is straightforward once the vulnerability vector is identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 3.2.6
Vendor Advisory: https://github.com/LabRedesCefetRJ/WeGIA/security/advisories/GHSA-qhfm-2qfp-h4m3
Restart Required: Yes
Instructions:
1. Backup your current WeGIA installation and database. 2. Download WeGIA version 3.2.6 from the official repository. 3. Replace the existing installation files with the new version. 4. Restart the web server service. 5. Verify the update was successful.
🔧 Temporary Workarounds
Implement Content Security Policy
allAdd a Content Security Policy header to restrict script execution sources
Add to web server config: Content-Security-Policy: default-src 'self'; script-src 'self'
Input Validation Filter
allImplement server-side input validation to sanitize user inputs
Implement input sanitization in affected PHP files using htmlspecialchars() or similar functions
🧯 If You Can't Patch
- Implement a Web Application Firewall (WAF) with XSS protection rules
- Disable or restrict access to the vulnerable functionality if possible
🔍 How to Verify
Check if Vulnerable:
Check the WeGIA version in the admin panel or by examining the application files. If version is below 3.2.6, the system is vulnerable.Check Version:
Check the version.php file or admin panel dashboardVerify Fix Applied:
After updating to 3.2.6, verify the version in the admin panel and test the previously vulnerable input fields with basic XSS payloads like <script>alert('test')</script>📡 Detection & Monitoring
