CVE-2025-9238: Exam-Seating-Arrangement SQLi Vulnerability

CVE-2025-9238 Overview

A SQL Injection vulnerability has been identified in the Swatadru Exam-Seating-Arrangement application, specifically affecting the Student Login component at /student.php. The vulnerability allows remote attackers to manipulate the email parameter to inject malicious SQL commands, potentially compromising the integrity and confidentiality of the application database. The exploit has been publicly disclosed and may be actively utilized by threat actors.

Critical Impact

Remote attackers can exploit this SQL Injection vulnerability to bypass authentication, extract sensitive student and exam data, modify database records, or potentially escalate to full database server compromise.

Affected Products

• Swatadru Exam-Seating-Arrangement (rolling release up to commit 97335ccebf95468d92525f4255a2241d2b0b002f)
• /student.php Student Login component
• All deployments using vulnerable versions of the application

Technical Details for CVE-2025-9238

Vulnerability Analysis

This vulnerability exists within the Student Login functionality of the Exam-Seating-Arrangement application. The email parameter in /student.php is processed without adequate input validation or parameterized queries, allowing attackers to inject arbitrary SQL statements. The network-accessible nature of this vulnerability enables remote exploitation without requiring authentication, making it particularly dangerous for publicly-facing deployments.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection vulnerabilities where user input is improperly handled before being processed by backend systems.

Root Cause

The root cause of this vulnerability is the lack of proper input sanitization and parameterized queries in the Student Login authentication logic. When user-supplied data from the email field is concatenated directly into SQL queries without escaping or prepared statements, attackers can break out of the intended query context and execute arbitrary SQL commands.

Attack Vector

The attack can be executed remotely over the network without requiring prior authentication. An attacker submits a specially crafted email parameter value to the /student.php endpoint that contains SQL injection payloads. These payloads can be designed to:

• Bypass authentication checks entirely
• Extract sensitive data from database tables
• Modify or delete existing records
• Enumerate database structure and contents

The vulnerability requires no user interaction and can be automated, making it suitable for mass exploitation attempts. Technical details and reproduction steps are available in the GitHub PoC Gist.

Detection Methods for CVE-2025-9238

Indicators of Compromise

• Unusual SQL syntax patterns in web server access logs for /student.php
• Repeated failed or anomalous login attempts with malformed email parameters
• Database query logs showing unexpected UNION SELECT, OR 1=1, or time-based injection patterns
• Unexplained database access or data exfiltration from student-related tables

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in the email parameter
• Monitor HTTP POST requests to /student.php for common SQL injection keywords and syntax
• Enable detailed database query logging and alert on queries containing injection indicators
• Deploy SentinelOne Singularity for endpoint and workload protection to detect post-exploitation activities

Monitoring Recommendations

• Configure SIEM alerts for patterns matching SQL injection attempts against the Student Login endpoint
• Establish baseline metrics for authentication requests and alert on anomalous volumes or patterns
• Review database audit logs regularly for unauthorized data access or schema enumeration attempts

How to Mitigate CVE-2025-9238

Immediate Actions Required

• Restrict network access to the Exam-Seating-Arrangement application to trusted IP ranges
• Implement input validation and sanitization for the email parameter immediately
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules
• Audit application logs and database logs for signs of previous exploitation attempts

Patch Information

The vendor was contacted about this vulnerability but did not respond. As this product uses a rolling release model without discrete version numbers, organizations should monitor the official repository for updates and ensure they are running the latest commit. Due to the lack of vendor response, organizations should prioritize implementing workarounds and consider alternative solutions. Additional vulnerability details are available at VulDB #320771.

Workarounds

• Replace direct SQL query concatenation with parameterized queries or prepared statements in /student.php
• Implement strict input validation for the email field, rejecting any input containing SQL metacharacters
• Deploy application-layer filtering to block common SQL injection patterns
• Consider placing the application behind a reverse proxy with SQL injection filtering capabilities
• Restrict database user privileges to minimum required permissions to limit impact of successful exploitation

# Example: Configure ModSecurity WAF rule to block SQL injection attempts
# Add to modsecurity.conf or rules configuration
SecRule ARGS:email "@detectSQLi" \
    "id:100001,\
    phase:2,\
    deny,\
    status:403,\
    log,\

    tag:'CVE-2025-9238'"
