CVE-2025-12238 Overview
CVE-2025-12238 is a SQL injection vulnerability in code-projects Automated Voting System 1.0. The flaw resides in an unknown function within /admin/user.php, where the Username argument is concatenated into a database query without proper sanitization [CWE-89]. Attackers can exploit the issue remotely over the network with low-privilege authentication. Public exploit details have been released, increasing the risk of opportunistic abuse against exposed installations. The vulnerability also maps to [CWE-74] for improper neutralization of special elements in output.
Critical Impact
Authenticated remote attackers can manipulate SQL queries through the Username parameter in /admin/user.php, leading to unauthorized data access or modification in the voting system database.
Affected Products
- code-projects Automated Voting System 1.0
- Fabian Automated Voting System (CPE: cpe:2.3:a:fabian:automated_voting_system:1.0)
- Deployments using the vulnerable /admin/user.php endpoint

Technical Details for CVE-2025-12238
Vulnerability Analysis
The vulnerability stems from improper neutralization of user input in the /admin/user.php administrative endpoint. The application accepts the Username parameter and inserts the value directly into a SQL statement. Attackers can append SQL syntax to the Username field to alter query logic.
Successful exploitation can expose user records, modify voting data, or escalate access within the application database. The attack requires network reachability to the admin interface and a low-privilege account. Because the affected file is under the /admin/ path, exposure is typically limited to authenticated administrative users, which lowers the practical impact.
The EPSS probability is 0.276% with a percentile rank of 19.073, reflecting low predicted exploitation likelihood despite the public exploit release.
Root Cause
The root cause is the absence of parameterized queries or input sanitization on the Username argument processed by /admin/user.php. User-controlled data flows directly into a SQL statement, allowing query structure manipulation. This pattern matches [CWE-89] SQL Injection.
Attack Vector
The attack vector is remote and network-based. An authenticated user with access to the admin interface submits a crafted Username value containing SQL metacharacters. The malicious payload alters the executed query, returning attacker-controlled data or modifying records.
No verified proof-of-concept code is available in trusted sources. Refer to the GitHub CVE Issue Discussion and VulDB #329908 Details for technical context.
Detection Methods for CVE-2025-12238
Indicators of Compromise
- HTTP requests to /admin/user.php containing SQL metacharacters such as single quotes, UNION, SELECT, --, or OR 1=1 in the Username parameter.
- Unexpected database errors or anomalous response sizes from /admin/user.php.
- Authentication or admin sessions performing repeated POST or GET requests with varying Username payloads.
Detection Strategies
- Deploy web application firewall rules that inspect the Username parameter on the /admin/user.php route for SQL injection signatures.
- Enable database query logging and alert on syntactically anomalous queries originating from the voting system service account.
- Correlate web access logs with database audit logs to identify request-to-query patterns matching injection attempts.
Monitoring Recommendations
- Monitor administrative endpoint access for unusual source IPs, especially from outside expected management networks.
- Track failed login attempts and subsequent successful access to /admin/user.php to identify credential-based pivoting.
- Alert on database response anomalies including extended query durations and large result sets returned to the admin interface.
How to Mitigate CVE-2025-12238
Immediate Actions Required
- Restrict network access to the /admin/ directory using IP allowlisting or VPN-only access.
- Rotate administrative credentials and enforce strong, unique passwords for all admin accounts.
- Review database logs for evidence of historical exploitation against the Username parameter.
Patch Information
No official vendor patch is currently referenced in the advisory sources. Organizations using code-projects Automated Voting System 1.0 should consult the Code Projects Resource Hub and the VulDB #329908 Incident Report for vendor updates. Until a fix is available, apply compensating controls at the application and network layers.
Workarounds
- Implement parameterized queries or prepared statements in /admin/user.php if maintaining a forked or customized deployment.
- Place the application behind a web application firewall with SQL injection signatures enabled and tuned for the Username parameter.
- Disable or remove the affected admin functionality if it is not required for operations.
- Apply input validation that rejects non-alphanumeric characters in the Username field before query construction.
