CVE-2023-34601
📋 TL;DR
Jeesite versions before commit 10742d3 contain a SQL injection vulnerability in the ActDao.xml component via the ${businessTable} parameter. This allows attackers to execute arbitrary SQL commands on the database. Any organization running vulnerable Jeesite installations is affected.
💻 Affected Systems
- Jeesite
📦 What is this software?
Jeesite by Jeesite
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data manipulation, or remote code execution on the database server.
Likely Case
Unauthorized data access, data exfiltration, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation and parameterized queries preventing successful exploitation.
🎯 Exploit Status
SQL injection vulnerabilities are commonly exploited and tooling exists for automated exploitation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Commit 10742d3 and later
Vendor Advisory: https://github.com/thinkgem/jeesite/issues/515
Restart Required: Yes
Instructions:
1. Update to Jeesite commit 10742d3 or later. 2. Replace vulnerable ${businessTable} usage with parameterized queries. 3. Restart the application server.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation for the businessTable parameter to allow only alphanumeric characters.
Add input validation in the controller layer before passing to ActDao.xml
WAF Rule
allDeploy web application firewall rules to block SQL injection patterns.
Configure WAF to detect and block SQL injection attempts on /act endpoints
🧯 If You Can't Patch
- Implement network segmentation to isolate the vulnerable system from critical assets
- Enable detailed SQL query logging and monitor for suspicious database activity
🔍 How to Verify
Check if Vulnerable:
Check if your Jeesite version is older than commit 10742d3 by examining the codebase or version metadata.Check Version:
git log --oneline | grep -i '10742d3' or check version in application propertiesVerify Fix Applied:
Verify that the ActDao.xml file no longer contains vulnerable ${businessTable} usage and uses parameterized queries instead.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts via /act endpoints
- SQL syntax errors in application logs
Network Indicators:
- Unusual outbound database connections
- SQL injection patterns in HTTP requests to /act endpoints
SIEM Query:
source="application.logs" AND "ActDao.xml" AND ("SQL" OR "injection" OR "businessTable")
