CVE-2025-26086
📋 TL;DR
An unauthenticated blind SQL injection vulnerability in RSI Queue Management System v3.0 allows attackers to remotely execute time-delayed SQL queries via the TaskID parameter. This enables time-based inference attacks to extract sensitive database contents without authentication. Organizations using RSI Queue Management System v3.0 are affected.
💻 Affected Systems
- RSI Queue Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including extraction of all sensitive data (user credentials, PII, system configurations), potential privilege escalation, and full system takeover.
Likely Case
Extraction of sensitive database information such as user credentials, personal data, and system configurations leading to data breach and potential lateral movement.
If Mitigated
Limited data exposure with proper input validation and WAF protection, though system remains vulnerable to skilled attackers.
🎯 Exploit Status
Exploitation requires time-based blind SQL injection techniques which are well-documented and tools exist to automate the process.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available or implementing workarounds.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allImplement WAF rules to block SQL injection patterns in TaskID parameter
# Example ModSecurity rule: SecRule ARGS:TaskID "@detectSQLi" "id:1001,phase:2,deny,status:403"
Input Validation Filter
allAdd input validation to sanitize TaskID parameter before processing
# Example PHP filter: $taskID = preg_replace('/[^0-9]/', '', $_GET['TaskID']);
🧯 If You Can't Patch
- Isolate the vulnerable system behind a reverse proxy with strict input validation
- Implement network segmentation to limit database access from the vulnerable application
🔍 How to Verify
Check if Vulnerable:
Test with time-based SQL injection payload: /endpoint?TaskID=1' AND (SELECT * FROM (SELECT(SLEEP(5)))a)--Check Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Test with same payload after implementing fixes - should return immediate response without delay📡 Detection & Monitoring
Log Indicators:
- Unusual long response times for TaskID requests
- Repeated requests with SQL keywords in TaskID parameter
- Multiple failed login attempts following TaskID manipulation
Network Indicators:
- Unusual database connection patterns from application server
- High volume of requests to vulnerable endpoint with varying TaskID values
SIEM Query:
source="web_logs" AND (uri="*TaskID=*" AND (response_time>5000 OR uri="*SLEEP*" OR uri="*WAITFOR*" OR uri="*BENCHMARK*"))
