CVE-2023-49625
📋 TL;DR
Billing Software v1.0 contains unauthenticated SQL injection vulnerabilities in the partylist_edit_submit.php resource, allowing attackers to execute arbitrary SQL commands without authentication. This affects all systems running the vulnerable software version.
💻 Affected Systems
- Billing Software
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, privilege escalation, and potential remote code execution on the database server.
Likely Case
Data exfiltration of sensitive billing information, customer data, and potential authentication bypass.
If Mitigated
Limited impact with proper input validation and database permissions, though SQL injection attempts would still be logged.
🎯 Exploit Status
SQL injection in the 'id' parameter is straightforward to exploit with common SQL injection techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.kashipara.com/
Restart Required: No
Instructions:
1. Check vendor website for updated version. 2. If patch available, download and install. 3. Validate input filtering is implemented. 4. Test functionality after update.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy WAF with SQL injection rules to block malicious requests
Input Validation Filter
allAdd input validation to sanitize 'id' parameter before processing
Example PHP: $id = filter_var($_GET['id'], FILTER_VALIDATE_INT); if($id === false) { die('Invalid input'); }
🧯 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 partylist_edit_submit.php endpoint with SQL injection payloads in the 'id' parameter (e.g., id=1' OR '1'='1)Check Version:
Check software documentation or interface for version informationVerify Fix Applied:
Test with same SQL injection payloads and verify they are rejected or properly sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed parameter validation attempts
