CVE-2023-31753
📋 TL;DR
This SQL injection vulnerability in eNdonesia 8.7 allows attackers to execute arbitrary SQL commands through the 'rid=' parameter in diskusi.php. Attackers can potentially read, modify, or delete database content, and in some cases achieve remote code execution. All systems running eNdonesia 8.7 with the vulnerable diskusi.php file are affected.

Endonesia by Endonesia
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, data destruction, and potential remote code execution on the underlying server.
Likely Case
Unauthorized data access, privilege escalation, and potential administrative account takeover.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only allowing data viewing.
🎯 Exploit Status
Public proof-of-concept code exists on GitHub, making exploitation straightforward for attackers with basic SQL injection knowledge.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version if available, or implement workarounds.
🔧 Temporary Workarounds
Input Validation and Sanitization
allAdd parameter validation and sanitization for the 'rid' parameter in diskusi.php
Edit diskusi.php to add: $rid = intval($_GET['rid']); // Convert to integer
Or implement prepared statements with parameterized queries
Web Application Firewall (WAF) Rules
allBlock SQL injection patterns targeting the rid parameter
Add WAF rule: Block requests with SQL keywords in rid parameter
Example pattern: rid=.*(SELECT|UNION|INSERT|DELETE|UPDATE|DROP|ALTER).*
🧯 If You Can't Patch
- Restrict access to diskusi.php using IP whitelisting or authentication
- Implement database user with minimal permissions (read-only if possible)
🔍 How to Verify
Check if Vulnerable:
Test by accessing diskusi.php with SQL injection payload in rid parameter: http://target/diskusi.php?rid=1' OR '1'='1Check Version:
Check eNdonesia version in configuration files or admin panelVerify Fix Applied:
Test with same payload after implementing fixes - should return error or no SQL injection behavior📡 Detection & Monitoring
Log Indicators:
- Unusual SQL errors in web server logs
- Multiple requests to diskusi.php with suspicious rid parameter values
- Database query errors containing SQL injection patterns
Network Indicators:
- HTTP requests with SQL keywords in GET parameters
- Unusual traffic patterns to diskusi.php endpoint
SIEM Query:
source="web_server_logs" AND uri="*diskusi.php*" AND (query="*SELECT*" OR query="*UNION*" OR query="*OR '1'='1*")
