CVE-2023-49622
📋 TL;DR
Billing Software v1.0 contains unauthenticated SQL injection vulnerabilities in the 'itemnameid' parameter of material_bill.php?action=itemRelation. This allows attackers to execute arbitrary SQL commands without authentication, potentially compromising the entire database. All users running Billing Software v1.0 are affected.
💻 Affected Systems
- Billing Software
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data destruction, and potential remote code execution leading to full system takeover.
Likely Case
Database information disclosure, data manipulation, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or limited data exposure.
🎯 Exploit Status
SQL injection is well-understood with many automated tools available. The unauthenticated nature makes exploitation trivial.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.kashipara.com/
Restart Required: No
Instructions:
No official patch available. Contact vendor for updated version or apply workarounds.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize the 'itemnameid' parameter before processing
Edit material_bill.php to add: $itemnameid = filter_var($_GET['itemnameid'], FILTER_VALIDATE_INT); if (!$itemnameid) { die('Invalid input'); }
Web Application Firewall
allDeploy WAF with SQL injection protection rules
🧯 If You Can't Patch
- Isolate the system behind a firewall with strict access controls
- Implement network segmentation to limit database access from the application server
🔍 How to Verify
Check if Vulnerable:
Test the endpoint with SQL injection payloads: material_bill.php?action=itemRelation&itemnameid=1' OR '1'='1
Check Version:
Check software version in admin panel or configuration files
Verify Fix Applied:
Test with same payloads and verify proper error handling or rejection of malicious input
