CVE-2023-24789
📋 TL;DR
CVE-2023-24789 is an authenticated SQL injection vulnerability in jeecg-boot's building block report component. Attackers with valid credentials can execute arbitrary SQL commands, potentially leading to data theft, modification, or deletion. Organizations using jeecg-boot v3.4.4 are affected.
💻 Affected Systems
- jeecg-boot
📦 What is this software?
Jeecg by Jeecg
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data exfiltration, privilege escalation, and potential remote code execution via database functions.
Likely Case
Unauthorized data access and manipulation, potentially exposing sensitive business information or user data.
If Mitigated
Limited impact with proper input validation, parameterized queries, and database user privilege restrictions.
🎯 Exploit Status
SQL injection vulnerabilities are commonly exploited, and authenticated access requirement reduces but doesn't eliminate risk.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v3.4.5 or later
Vendor Advisory: https://github.com/jeecgboot/jeecg-boot/issues/4511
Restart Required: Yes
Instructions:
1. Backup your application and database. 2. Update jeecg-boot to v3.4.5 or later. 3. Restart the application server. 4. Verify the fix by testing the building block report component.
🔧 Temporary Workarounds
Disable Building Block Report Component
allTemporarily disable or restrict access to the vulnerable component until patching is complete.
Modify application configuration to disable report module access
Implement WAF Rules
allDeploy web application firewall rules to block SQL injection patterns targeting the report endpoint.
Configure WAF with SQL injection detection rules for /jeecg-boot/report/* endpoints
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries for all report component inputs.
- Apply principle of least privilege to database accounts used by the application.
🔍 How to Verify
Check if Vulnerable:
Check if running jeecg-boot v3.4.4 and test the building block report component with SQL injection payloads.Check Version:
Check application.properties or pom.xml for version information, or use the application's about/version endpoint.Verify Fix Applied:
Verify version is v3.4.5 or later and test that SQL injection attempts are properly rejected.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed authentication attempts followed by report component access
- Long or malformed parameter values in application logs
Network Indicators:
- SQL keywords in HTTP POST parameters to report endpoints
- Unusual database connection patterns from application server
SIEM Query:
source="application.log" AND "report" AND ("SELECT" OR "UNION" OR "INSERT" OR "DELETE")
