CVE-2025-8238 Overview
A SQL injection vulnerability has been identified in code-projects Exam Form Submission version 1.0. The vulnerability exists in the /admin/update_s2.php file, where the credits parameter is improperly handled, allowing attackers to inject malicious SQL commands. This flaw enables remote attackers to manipulate database queries without authentication, potentially compromising the entire application database.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to read, modify, or delete sensitive data in the application database, including student records and exam submissions.

Technical Details for CVE-2025-8238
Vulnerability Analysis
This vulnerability is classified as SQL Injection (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component). The affected endpoint /admin/update_s2.php fails to properly sanitize user input passed through the credits parameter before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL statements that the database server will execute.
The vulnerability is remotely exploitable and requires no authentication, making it particularly dangerous for internet-facing deployments. An attacker can leverage this flaw to extract sensitive information from the database, modify or delete existing records, or potentially escalate privileges depending on the database configuration and permissions.
Root Cause
The root cause of this vulnerability is insufficient input validation and lack of parameterized queries in the /admin/update_s2.php file. The credits parameter is directly concatenated into SQL statements without proper sanitization or escaping, violating secure coding practices for database interactions. The application fails to use prepared statements or stored procedures that would prevent SQL injection attacks.
Attack Vector
The attack vector is network-based, allowing remote exploitation without any user interaction or prior authentication. An attacker can craft malicious HTTP requests to the vulnerable endpoint, embedding SQL injection payloads within the credits parameter. The exploit has been publicly disclosed, increasing the risk of widespread exploitation.
The attack flow typically involves:
- Identifying the vulnerable parameter in /admin/update_s2.php
- Crafting a malicious request with SQL injection payloads in the credits field
- Sending the request to extract data, modify records, or perform other unauthorized database operations
For technical details on the exploitation methodology, refer to the GitHub Issue Discussion where the vulnerability was disclosed.
Detection Methods for CVE-2025-8238
Indicators of Compromise
- Unusual or malformed requests to /admin/update_s2.php containing SQL syntax characters such as single quotes, double dashes, or UNION statements
- Database error messages in application logs indicating malformed SQL queries
- Unexpected database queries or data extraction attempts in database audit logs
- Access to the update_s2.php endpoint from suspicious IP addresses or geographic locations
Detection Strategies
- Implement web application firewall (WAF) rules to detect and block SQL injection patterns targeting the credits parameter
- Monitor HTTP request logs for anomalous payloads containing SQL injection signatures (e.g., ' OR 1=1, UNION SELECT, --)
- Enable database query logging and alert on unusual query patterns or error conditions
- Deploy SentinelOne Singularity to detect exploitation attempts and suspicious process behavior
Monitoring Recommendations
- Set up real-time alerting for any requests to /admin/update_s2.php containing non-numeric values in the credits parameter
- Monitor database connection logs for unusual query execution times or result set sizes
- Implement anomaly detection for database read/write patterns that deviate from baseline behavior
How to Mitigate CVE-2025-8238
Immediate Actions Required
- Restrict access to the /admin/update_s2.php endpoint using network-level controls or authentication requirements
- Deploy a web application firewall with SQL injection protection rules
- If possible, take the vulnerable application offline until a patch is available
- Review database logs for any signs of prior exploitation
Patch Information
No official vendor patch is currently available for this vulnerability. Organizations using code-projects Exam Form Submission 1.0 should implement the workarounds described below and monitor the Code Projects Homepage for updates.
For additional vulnerability intelligence, refer to the VulDB #317826 entry.
Workarounds
- Modify the application source code to implement parameterized queries or prepared statements for all database interactions involving user input
- Add input validation to ensure the credits parameter only accepts expected numeric values
- Deploy a reverse proxy or WAF with SQL injection filtering capabilities in front of the application
- Implement database user privilege restrictions to limit the impact of successful SQL injection attacks
# Example: Restrict access to vulnerable endpoint using Apache .htaccess
<Files "update_s2.php">
Order Deny,Allow
Deny from all
Allow from 192.168.1.0/24
</Files>
