CVE-2023-49622

9.8 CRITICAL

📋 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

Products:
  • Billing Software
Versions: v1.0
Operating Systems: All platforms running the software
Default Config Vulnerable: ⚠️ Yes
Notes: All installations of v1.0 are vulnerable by default. No special configuration required for exploitation.

📦 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.

🌐 Internet-Facing: HIGH - Unauthenticated exploitation makes this extremely dangerous for internet-facing instances.
🏢 Internal Only: HIGH - Even internal systems are vulnerable to insider threats or compromised internal accounts.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

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

all

Add 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

all

Deploy 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

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL error messages in application logs
  • Multiple failed login attempts following SQL injection patterns
  • Unusual database queries from application user

Network Indicators:

  • HTTP requests with SQL keywords in parameters
  • Unusual traffic patterns to material_bill.php endpoint

SIEM Query:

source="web_logs" AND (uri="*material_bill.php*" AND (param="*itemnameid*" AND (value="*' OR*" OR value="*' UNION*" OR value="*' SELECT*")))
