CVE-2025-5225: Campcodes Voting System SQLi Vulnerability

CVE-2025-5225 is a critical SQL injection vulnerability in Campcodes Advanced Online Voting System 1.0 affecting the /index.php file. This article covers technical details, affected versions, security impact, and mitigation.

Published: March 24, 2026

CVE-2025-5225 Overview

A critical SQL injection vulnerability has been discovered in Campcodes Advanced Online Voting System 1.0. The vulnerability exists in the /index.php file where improper handling of the voter parameter allows attackers to inject malicious SQL queries. This flaw can be exploited remotely without authentication, potentially leading to unauthorized data access, data manipulation, and compromise of the voting system's integrity.

Critical Impact

Unauthenticated attackers can exploit this SQL injection vulnerability remotely to extract sensitive voter data, manipulate election results, or gain unauthorized access to the underlying database.

Affected Products

  • Campcodes Advanced Online Voting System 1.0

Discovery Timeline

  • May 27, 2025 - CVE-2025-5225 published to NVD
  • May 28, 2025 - Last updated in NVD database

Technical Details for CVE-2025-5225

Vulnerability Analysis

This SQL injection vulnerability affects the authentication and voter lookup functionality within the Advanced Online Voting System. The voter parameter passed to /index.php is not properly sanitized before being incorporated into SQL queries, allowing attackers to manipulate the query logic. This is a classic injection vulnerability where user-supplied input is directly concatenated into database queries without adequate input validation or parameterized query usage.

The vulnerability is accessible over the network without requiring any authentication or user interaction, making it particularly dangerous for internet-facing deployments. Successful exploitation could allow attackers to bypass authentication mechanisms, extract sensitive voter information, modify voting records, or potentially escalate to remote code execution depending on the database configuration and underlying system.

Root Cause

The root cause of this vulnerability is improper input validation and lack of parameterized queries (CWE-89: SQL Injection, CWE-74: Injection). The application fails to sanitize user input provided through the voter parameter before using it in SQL statements. This allows malicious SQL syntax to be injected and executed by the database engine, bypassing intended query logic.

Attack Vector

The attack is network-based and can be initiated remotely against any exposed instance of the Advanced Online Voting System. An attacker crafts a malicious HTTP request to /index.php containing SQL injection payloads in the voter parameter. The server processes this parameter without proper sanitization, executing the injected SQL commands against the backend database.

Typical exploitation scenarios include:

  • Authentication bypass by manipulating login queries
  • Data exfiltration using UNION-based or blind SQL injection techniques
  • Database enumeration to discover table structures and sensitive data
  • Potential database modification including vote manipulation

Since the exploit has been publicly disclosed, detailed technical information is available through the GitHub Issue Tracker and VulDB entry #310323.

Detection Methods for CVE-2025-5225

Indicators of Compromise

  • Unusual SQL syntax patterns in web server access logs targeting /index.php
  • Error messages in application logs indicating SQL syntax errors or unexpected database behavior
  • Multiple requests to /index.php with encoded special characters in the voter parameter (e.g., ', --, UNION, SELECT)
  • Unexpected database queries or data extraction patterns in database audit logs

Detection Strategies

  • Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the voter parameter
  • Configure database query logging and monitor for anomalous query structures or unauthorized data access
  • Deploy intrusion detection signatures for common SQL injection payloads targeting PHP applications
  • Review web server logs for requests containing typical SQLi characters and keywords

Monitoring Recommendations

  • Enable verbose logging on the web server and database to capture suspicious activity
  • Set up alerts for failed database authentication attempts or SQL syntax errors
  • Monitor for bulk data extraction patterns that could indicate successful exploitation
  • Track changes to critical database tables, particularly voter and election result tables

How to Mitigate CVE-2025-5225

Immediate Actions Required

  • Restrict access to the Advanced Online Voting System to trusted networks or IP addresses until a patch is available
  • Implement a Web Application Firewall (WAF) with SQL injection protection rules
  • Review and audit web server access logs for signs of exploitation attempts
  • Consider taking the application offline if it contains sensitive data and no patch is available

Patch Information

No vendor patch information is currently available from Campcodes. Organizations should monitor the CampCodes website for security updates. Until an official patch is released, implementing the workarounds below is strongly recommended.

Workarounds

  • Deploy a Web Application Firewall (WAF) configured to filter SQL injection payloads targeting the voter parameter
  • Implement input validation at the application level using prepared statements or parameterized queries if source code access is available
  • Restrict database user privileges to limit the impact of successful SQL injection attacks
  • Isolate the voting system on a separate network segment with strict access controls
  • If possible, implement allow-list validation for the voter parameter to only accept expected input formats
bash
# Example: Apache ModSecurity rule to block SQLi attempts on voter parameter
SecRule ARGS:voter "@detectSQLi" \
    "id:100001,\
    phase:2,\
    deny,\
    status:403,\
    log,\
    msg:'SQL Injection detected in voter parameter',\
    tag:'CVE-2025-5225'"
