CVE-2025-32429
📋 TL;DR
This CVE describes a critical SQL injection vulnerability in XWiki Platform that allows unauthenticated attackers to execute arbitrary SQL commands via the 'sort' parameter in getdeleteddocuments.vm. The vulnerability affects all XWiki instances running vulnerable versions, potentially compromising database integrity and confidentiality.
💻 Affected Systems
- XWiki Platform
📦 What is this software?
Xwiki by Xwiki
Xwiki by Xwiki
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, privilege escalation, and potential remote code execution via database functions.
Likely Case
Data exfiltration, unauthorized data modification, and potential authentication bypass through database manipulation.
If Mitigated
Limited impact if proper input validation and parameterized queries are implemented, though SQL injection remains a serious threat.
🎯 Exploit Status
SQL injection via ORDER BY parameter is well-understood and easily weaponized. No authentication required makes exploitation trivial.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 16.10.6 and 17.3.0-rc-1
Vendor Advisory: https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-vr59-gm53-v7cq
Restart Required: Yes
Instructions:
1. Backup your XWiki instance and database. 2. Download and install XWiki version 16.10.6 or 17.3.0-rc-1 from official sources. 3. Follow XWiki upgrade documentation for your specific deployment. 4. Restart the XWiki service. 5. Verify the fix by checking version and testing the vulnerable endpoint.
🔧 Temporary Workarounds
Input Validation Filter
allImplement web application firewall or input validation to block SQL injection patterns in the 'sort' parameter
# Configure WAF rules to block SQL patterns in GET parameters
# Example mod_security rule: SecRule ARGS:sort "@detectSQLi" "id:1001,phase:2,deny"
Access Restriction
linuxRestrict access to the vulnerable endpoint using network controls or authentication
# Apache/Nginx config to restrict /getdeleteddocuments.vm
location ~* /getdeleteddocuments\.vm$ { deny all; }
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries for all database interactions
- Deploy web application firewall with SQL injection detection rules and monitor for exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check if your XWiki version falls within affected ranges and test the /getdeleteddocuments.vm endpoint with SQL injection payloads in the 'sort' parameter.Check Version:
Check XWiki administration panel or view /xwiki/bin/view/Main/WebHome page source for version informationVerify Fix Applied:
After patching, verify the version is 16.10.6+ or 17.3.0-rc-1+, and test that SQL injection attempts in the 'sort' parameter are properly sanitized or rejected.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple requests to /getdeleteddocuments.vm with suspicious 'sort' parameters
- Database error messages containing SQL syntax errors
Network Indicators:
- HTTP requests with SQL keywords (UNION, SELECT, INSERT) in GET parameters
- Unusual database connection patterns from web server
SIEM Query:
source="web_logs" AND uri="/getdeleteddocuments.vm" AND (param_sort CONTAINS "UNION" OR param_sort CONTAINS "SELECT" OR param_sort CONTAINS "INSERT")
