CVE-2023-24084
📋 TL;DR
CVE-2023-24084 is a critical SQL injection vulnerability in ChiKoi v1.0 that allows attackers to execute arbitrary SQL commands via the load_file function. This affects all users running the vulnerable version of ChiKoi software, potentially leading to complete database compromise.
💻 Affected Systems
- ChiKoi
📦 What is this software?
Chikoi by Chikoi Project
⚠️ Risk & Real-World Impact
Worst Case
Complete database takeover, data exfiltration, privilege escalation, and potential remote code execution on the database server.
Likely Case
Unauthorized data access, data manipulation, and potential credential theft from the database.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or limited data exposure.
🎯 Exploit Status
SQL injection vulnerabilities are commonly exploited with automated tools. The public GitHub repository contains proof-of-concept details.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative software or implementing workarounds.
🔧 Temporary Workarounds
Input Validation and Parameterized Queries
allImplement proper input validation and use parameterized queries/prepared statements for all database operations.
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block exploitation attempts.
🧯 If You Can't Patch
- Isolate the ChiKoi application in a segmented network zone with strict access controls.
- Implement database-level controls: use least privilege accounts, enable database auditing, and restrict file system access.
🔍 How to Verify
Check if Vulnerable:
Check if you're running ChiKoi v1.0. Review application code for use of load_file function without proper input validation.Check Version:
Check application configuration files or documentation for version information.Verify Fix Applied:
Test the application with SQL injection payloads to ensure they're properly rejected. Review code changes implementing parameterized queries.📡 Detection & Monitoring
Log Indicators:
- Unusual database queries, SQL syntax errors in application logs, multiple failed login attempts with SQL payloads
Network Indicators:
- HTTP requests containing SQL keywords (SELECT, UNION, etc.) in parameters, unusual database connection patterns
SIEM Query:
source="web_logs" AND ("load_file" OR "UNION SELECT" OR "' OR '1'='1")
