CVE-2026-23731

4.3 MEDIUM

📋 TL;DR

This CVE describes a clickjacking vulnerability in WeGIA web management software for charitable institutions. Attackers can embed WeGIA pages in malicious frames to trick users into unintended interactions with sensitive workflows. All users running WeGIA versions before 3.6.2 are affected.

💻 Affected Systems

Products:
  • WeGIA
Versions: All versions prior to 3.6.2
Operating Systems: All
Default Config Vulnerable: ⚠️ Yes
Notes: All default installations are vulnerable as the missing security headers are not configured by default.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Users could be tricked into performing unauthorized administrative actions, financial transactions, or data modifications by interacting with hidden/deceptive interface elements.

🟠

Likely Case

Attackers create convincing phishing pages that overlay deceptive elements on legitimate WeGIA interfaces, leading to accidental data exposure or unintended actions.

🟢

If Mitigated

With proper framing protection headers, WeGIA pages cannot be embedded in malicious frames, preventing clickjacking attacks entirely.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Clickjacking attacks are well-documented and easy to implement. No authentication is required to embed vulnerable pages in frames.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 3.6.2

Vendor Advisory: https://github.com/LabRedesCefetRJ/WeGIA/security/advisories/GHSA-99qp-hjvh-c59q

Restart Required: Yes

Instructions:

1. Download WeGIA version 3.6.2 from the official repository. 2. Backup your current installation. 3. Replace files with the patched version. 4. Restart the web server.

🔧 Temporary Workarounds

Add X-Frame-Options Header

all

Configure web server to send X-Frame-Options: DENY or SAMEORIGIN header for all WeGIA responses

For Apache: Header always set X-Frame-Options "DENY"
For Nginx: add_header X-Frame-Options "DENY" always;

Add Content-Security-Policy Header

all

Configure web server to send Content-Security-Policy with frame-ancestors directive

For Apache: Header always set Content-Security-Policy "frame-ancestors 'none'"
For Nginx: add_header Content-Security-Policy "frame-ancestors 'none'" always;

🧯 If You Can't Patch

  • Implement web application firewall (WAF) rules to add X-Frame-Options or Content-Security-Policy headers
  • Use browser extensions or policies to enforce framing restrictions for WeGIA domains

🔍 How to Verify

Check if Vulnerable:

Use browser developer tools or curl to check HTTP response headers: curl -I https://your-wegia-instance.com | grep -i 'frame-options\|content-security-policy'

Check Version:

Check WeGIA version in admin interface or read version file if available

Verify Fix Applied:

Verify that X-Frame-Options: DENY or Content-Security-Policy with frame-ancestors directive is present in HTTP responses

📡 Detection & Monitoring

Log Indicators:

  • Multiple failed authentication attempts from same IP with unusual referrer headers
  • User complaints about unexpected interface behavior

Network Indicators:

  • HTTP requests with suspicious referrer domains
  • Multiple iframe embedding attempts from external domains

SIEM Query:

http.response.headers contains "X-Frame-Options" AND http.response.headers !contains "DENY" AND http.response.headers !contains "SAMEORIGIN"
