CVE-2024-24004
📋 TL;DR
CVE-2024-24004 is a critical SQL injection vulnerability in jshERP v3.3 that allows attackers to bypass the application's SQL protection mechanism. Attackers can exploit this by injecting malicious payloads through the 'column' and 'order' parameters in the findInOutDetail() function, potentially gaining unauthorized database access. All organizations using the vulnerable jshERP version are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, privilege escalation, and potential remote code execution through database functions.
Likely Case
Unauthorized data access, extraction of sensitive business information, and potential authentication bypass.
If Mitigated
Limited impact with proper input validation, parameterized queries, and network segmentation in place.
🎯 Exploit Status
Exploitation requires authentication to access the vulnerable endpoint, but the SQL injection technique is straightforward once authenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v3.3.1 or later
Vendor Advisory: https://github.com/jishenghua/jshERP/issues/99
Restart Required: Yes
Instructions:
1. Backup your current jshERP installation and database. 2. Download the latest version from the official repository. 3. Replace the vulnerable files with patched versions. 4. Restart the jshERP application server. 5. Verify the fix by testing the vulnerable endpoint.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation for 'column' and 'order' parameters to only allow expected values.
WAF Rule Implementation
allDeploy web application firewall rules to block SQL injection patterns targeting the vulnerable endpoint.
🧯 If You Can't Patch
- Implement network segmentation to isolate jshERP from critical systems
- Enable detailed SQL query logging and monitor for injection patterns
🔍 How to Verify
Check if Vulnerable:
Test the /depotHead/findInOutDetail endpoint with SQL injection payloads in 'column' or 'order' parameters while authenticated.Check Version:
Check the jshERP version in the application interface or configuration files.Verify Fix Applied:
Attempt the same SQL injection tests after patching; successful queries should be blocked or sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple failed login attempts followed by SQL injection patterns
- Database error messages containing SQL syntax
Network Indicators:
- HTTP requests to /depotHead/findInOutDetail with suspicious parameters
- Unusual database connection patterns from application server
SIEM Query:
source="jshERP_logs" AND ("column=" OR "order=") AND ("UNION" OR "SELECT" OR "INSERT" OR "UPDATE" OR "DELETE" OR "--" OR "' OR '")
