CVE-2026-2176
📋 TL;DR
This SQL injection vulnerability in code-projects Contact Management System 1.0 allows remote attackers to execute arbitrary SQL commands by manipulating the selecteditem[0] parameter in index.py. This affects all users running the vulnerable version of this contact management software.
💻 Affected Systems
- code-projects Contact Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, and potential remote code execution through database functions.
Likely Case
Unauthorized access to contact data, extraction of sensitive information, and potential database corruption.
If Mitigated
Limited impact with proper input validation and database permissions restricting damage to non-sensitive data.
🎯 Exploit Status
SQL injection vulnerabilities are typically easy to exploit with basic knowledge of SQL and web application testing tools.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://code-projects.org/
Restart Required: No
Instructions:
No official patch available. Consider implementing parameterized queries or input validation as workaround.
🔧 Temporary Workarounds
Implement Parameterized Queries
allModify index.py to use parameterized queries instead of string concatenation for SQL statements.
# Replace vulnerable code with parameterized queries
# Example: cursor.execute("SELECT * FROM contacts WHERE id = %s", (selecteditem[0],))
Input Validation
allAdd input validation to sanitize the selecteditem[0] parameter before processing.
# Add validation: if not selecteditem[0].isdigit(): return error
# Or use regex validation for expected input format
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block SQL injection patterns
- Restrict network access to only trusted IP addresses
🔍 How to Verify
Check if Vulnerable:
Check if index.py contains unsanitized use of selecteditem[0] parameter in SQL queries. Test with SQL injection payloads like ' OR '1'='1.Check Version:
Check the software version in documentation or configuration files. The vulnerable version is specifically 1.0.Verify Fix Applied:
Test with SQL injection payloads after implementing fixes to ensure they are properly blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual SQL error messages in application logs
- Multiple failed login attempts or parameter manipulation attempts
- Long or unusual parameter values in selecteditem[0]
Network Indicators:
- SQL keywords in HTTP parameters (SELECT, UNION, etc.)
- Unusual database connection patterns
SIEM Query:
search index=web_logs "selecteditem[0]" AND ("SELECT" OR "UNION" OR "OR '1'='1")
