CVE-2025-51825
📋 TL;DR
JeecgBoot versions 3.4.3 through 3.8.0 contain a SQL injection vulnerability in the /jeecg-boot/online/cgreport/head/parseSql endpoint that bypasses SQL blacklist restrictions. This allows attackers to execute arbitrary SQL commands against the database. Organizations using affected JeecgBoot versions are vulnerable.
💻 Affected Systems
- JeecgBoot

⚠️ Risk & Real-World Impact
Worst Case
Full database compromise including data theft, modification, deletion, or potential remote code execution via database functions.
Likely Case
Data exfiltration from the database, privilege escalation, or unauthorized data manipulation.
If Mitigated
Limited impact due to proper input validation, parameterized queries, and database permission restrictions.
🎯 Exploit Status
Exploitation requires understanding of SQL injection techniques and bypassing blacklist filters. No public exploit code available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 3.8.1 or later
Vendor Advisory: https://github.com/jeecgboot/JeecgBoot/issues/8335
Restart Required: No
Instructions:
1. Upgrade JeecgBoot to version 3.8.1 or later. 2. Verify the patch is applied by checking the version. 3. Test the vulnerable endpoint to ensure SQL injection is no longer possible.
🔧 Temporary Workarounds
Disable vulnerable endpoint
allBlock access to the /jeecg-boot/online/cgreport/head/parseSql endpoint via web server configuration or application firewall.
# Example for nginx: location ~ ^/jeecg-boot/online/cgreport/head/parseSql { deny all; }
# Example for Apache: <Location "/jeecg-boot/online/cgreport/head/parseSql"> Require all denied </Location>
Implement WAF rules
allDeploy web application firewall rules to detect and block SQL injection attempts targeting this endpoint.
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries for all SQL operations.
- Restrict database user permissions to minimum required privileges.
🔍 How to Verify
Check if Vulnerable:
Test the /jeecg-boot/online/cgreport/head/parseSql endpoint with SQL injection payloads that bypass blacklist filters.Check Version:
Check the JeecgBoot application version in the admin interface or configuration files.Verify Fix Applied:
After patching, retest the endpoint with the same SQL injection payloads to confirm they are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in application logs
- Multiple requests to /jeecg-boot/online/cgreport/head/parseSql with SQL keywords
- Database error messages containing SQL syntax
Network Indicators:
- HTTP POST requests to the vulnerable endpoint with SQL payloads
- Unusual database connection patterns from the application server
SIEM Query:
source="web_logs" AND uri="/jeecg-boot/online/cgreport/head/parseSql" AND (payload CONTAINS "SELECT" OR payload CONTAINS "UNION" OR payload CONTAINS "OR")
