CVE-2025-9926: Travel Management System SQLi Vulnerability

CVE-2025-9926 Overview

A SQL injection vulnerability has been identified in Projectworlds Travel Management System version 1.0. The vulnerability exists in the /viewsubcategory.php file, where improper handling of the t1 parameter allows attackers to inject malicious SQL queries. This flaw enables remote attackers to manipulate database queries, potentially leading to unauthorized data access, data modification, or complete database compromise.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability without authentication to extract sensitive data, modify database contents, or potentially gain unauthorized access to the underlying system.

Affected Products

• Projectworlds Travel Management System 1.0

Technical Details for CVE-2025-9926

Vulnerability Analysis

This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affects the viewsubcategory.php file in Projectworlds Travel Management System. The vulnerability stems from insufficient input validation and sanitization of the t1 parameter before it is incorporated into SQL queries.

When a user submits a request containing the t1 parameter, the application fails to properly sanitize or parameterize the input before constructing database queries. This allows an attacker to inject arbitrary SQL commands that will be executed by the database server with the same privileges as the application's database connection.

The exploit for this vulnerability has been publicly disclosed, increasing the risk of active exploitation. The attack can be carried out remotely without requiring authentication, making internet-facing installations particularly vulnerable.

Root Cause

The root cause of this vulnerability is improper input validation in the /viewsubcategory.php file. The application directly incorporates user-supplied data from the t1 parameter into SQL queries without proper sanitization, prepared statements, or parameterized queries. This classic injection flaw allows attackers to break out of the intended query context and execute arbitrary SQL commands.

Attack Vector

The attack vector is network-based, allowing remote exploitation without user interaction or authentication requirements. An attacker can craft malicious HTTP requests containing SQL injection payloads in the t1 parameter of requests to /viewsubcategory.php. The injected SQL code is then executed by the database server, potentially allowing the attacker to:

• Extract sensitive data from the database including user credentials and travel records
• Modify or delete database contents
• Bypass authentication mechanisms
• In some configurations, execute operating system commands through database features

The vulnerability can be exploited through standard web browsers, automated scanning tools, or custom HTTP requests targeting the vulnerable endpoint.

Detection Methods for CVE-2025-9926

Indicators of Compromise

• Unusual SQL error messages in application logs originating from /viewsubcategory.php
• Suspicious requests to /viewsubcategory.php containing SQL syntax characters such as single quotes, semicolons, or SQL keywords in the t1 parameter
• Database query logs showing unexpected UNION SELECT, DROP, INSERT, or UPDATE statements
• Unexpected data exfiltration patterns or database access from the web application

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP parameters
• Configure application logging to capture all requests to /viewsubcategory.php with parameter values
• Deploy database activity monitoring to alert on anomalous query patterns or unauthorized data access
• Use intrusion detection systems (IDS) with SQL injection signature detection capabilities

Monitoring Recommendations

• Monitor web server access logs for requests to /viewsubcategory.php with suspicious t1 parameter values
• Set up alerts for database errors or exceptions originating from the travel management application
• Review database audit logs for unusual SELECT statements or data access patterns
• Implement real-time monitoring for outbound data transfers that may indicate successful data exfiltration

How to Mitigate CVE-2025-9926

Immediate Actions Required

• Restrict network access to the Travel Management System to trusted IP ranges only
• Implement WAF rules to block SQL injection attempts targeting the t1 parameter
• Consider taking the application offline until a patch is available or code remediation is complete
• Review database access logs for evidence of prior exploitation
• Apply principle of least privilege to the database account used by the application

Patch Information

No official vendor patch information is currently available for this vulnerability. Organizations using Projectworlds Travel Management System 1.0 should contact the vendor for remediation guidance or consider implementing code-level fixes. Technical details about this vulnerability can be found in the GitHub Issue #9 and VulDB Entry #322328.

Workarounds

• Implement input validation to sanitize the t1 parameter before use in database queries
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules
• Restrict access to /viewsubcategory.php through network segmentation or authentication requirements
• If source code access is available, modify the application to use parameterized queries or prepared statements
• Consider implementing a reverse proxy that filters malicious SQL injection payloads
