CVE-2025-4794 Overview
A SQL injection vulnerability has been identified in PHPGurukul Online Course Registration version 3.1. This critical security flaw exists in the /news.php file, where improper handling of the newstitle parameter allows attackers to inject malicious SQL queries. The vulnerability can be exploited remotely without authentication, potentially allowing unauthorized access to sensitive database information, data manipulation, and system compromise.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database contents, or potentially gain unauthorized access to the underlying system through the /news.php endpoint.
Affected Products
- PHPGurukul Online Course Registration version 3.1
- Web applications using the vulnerable /news.php component
- Systems with the newstitle parameter exposed to user input

Technical Details for CVE-2025-4794
Vulnerability Analysis
This SQL injection vulnerability (CWE-89) stems from insufficient input validation in the /news.php file of PHPGurukul Online Course Registration. The application fails to properly sanitize user-supplied input in the newstitle parameter before incorporating it into SQL queries. This allows attackers to manipulate the database query structure by injecting malicious SQL syntax.
The vulnerability is classified under both CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The attack can be launched remotely over the network without requiring any authentication or user interaction, making it particularly dangerous for publicly accessible installations.
Root Cause
The root cause of this vulnerability is improper input validation and the lack of parameterized queries or prepared statements in the PHP code handling the newstitle parameter. When user input is directly concatenated into SQL queries without proper sanitization or escaping, attackers can break out of the intended query context and inject arbitrary SQL commands.
Attack Vector
The attack is network-based, requiring no authentication or special privileges. An attacker can craft malicious HTTP requests containing SQL injection payloads in the newstitle parameter sent to the /news.php endpoint. The exploit has been publicly disclosed, increasing the risk of widespread exploitation against unpatched systems.
Attackers typically exploit this vulnerability by submitting specially crafted input through form fields or URL parameters that contain SQL metacharacters and commands. This can lead to unauthorized data extraction, modification of database records, authentication bypass, or in severe cases, command execution on the underlying server through database features like xp_cmdshell or INTO OUTFILE.
Detection Methods for CVE-2025-4794
Indicators of Compromise
- Unusual database queries originating from the /news.php endpoint containing SQL metacharacters such as single quotes, semicolons, or UNION statements
- HTTP request logs showing suspicious newstitle parameter values with SQL syntax patterns
- Database error messages appearing in web server logs indicating malformed queries
- Unexpected database modifications or data exfiltration attempts
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the newstitle parameter
- Monitor database query logs for anomalous queries containing UNION, SELECT, INSERT, UPDATE, DELETE, or DROP statements from the application context
- Deploy intrusion detection systems (IDS) with SQL injection signature rules focusing on the /news.php endpoint
- Enable PHP error logging and monitor for database-related errors that may indicate exploitation attempts
Monitoring Recommendations
- Configure real-time alerting for HTTP requests to /news.php containing SQL injection indicators
- Implement database activity monitoring to detect unauthorized data access or modification
- Review web server access logs regularly for patterns consistent with SQL injection scanning or exploitation
- Monitor for bulk data extraction or unusual query execution times that may indicate successful exploitation
How to Mitigate CVE-2025-4794
Immediate Actions Required
- Restrict public access to the /news.php endpoint until a patch is applied
- Implement input validation and sanitization for the newstitle parameter at the application level
- Deploy WAF rules to block known SQL injection attack patterns
- Review database permissions to limit the application's database user privileges following the principle of least privilege
Patch Information
As of the last NVD update on 2025-05-21, no official vendor patch has been publicly announced for this vulnerability. Organizations should monitor the PHP Gurukul website for security updates and patch releases. Additional technical details can be found in the GitHub Issue Discussion and VulDB advisory #309103.
Workarounds
- Implement prepared statements with parameterized queries in the PHP code handling the newstitle input
- Apply strict input validation using allowlists for acceptable characters in the newstitle parameter
- Use PHP's mysqli_real_escape_string() or PDO prepared statements as an interim measure
- Consider taking the affected functionality offline or restricting access via IP allowlisting until a proper fix is implemented
# Configuration example - Apache .htaccess to restrict access to vulnerable endpoint
<Files "news.php">
Order Deny,Allow
Deny from all
