CVE-2018-25161 in Warranty Tracking System
Summary
by MITRE • 03/06/2026
Warranty Tracking System 11.06.3 contains an SQL injection vulnerability that allows attackers to execute arbitrary SQL queries by injecting malicious code through the txtCustomerCode, txtCustomerName, and txtPhone POST parameters in SearchCustomer.php. Attackers can submit crafted SQL statements using UNION SELECT to extract sensitive database information including usernames, database names, and version details.

The warranty tracking system version 11.06.3 presents a critical sql injection vulnerability that fundamentally compromises database security through improper input validation. This vulnerability exists within the SearchCustomer.php script where user-supplied parameters txtCustomerCode, txtCustomerName, and txtPhone are directly incorporated into sql queries without adequate sanitization or parameterization. The flaw represents a classic sql injection attack vector that enables malicious actors to manipulate database operations through crafted input payloads. The vulnerability classification aligns with cwe-89 sql injection, which specifically addresses the improper handling of sql commands within application code. Attackers can exploit this weakness by injecting malicious sql code through the post parameters, leveraging union select statements to extract sensitive information from underlying database systems.
The operational impact of this vulnerability extends beyond simple data exfiltration to encompass complete database compromise and potential system infiltration. Successful exploitation allows attackers to extract usernames, database names, and version information, providing adversaries with critical intelligence for further attacks. The vulnerability enables unauthorized access to customer data, warranty records, and potentially sensitive business information stored within the system. This exposure creates opportunities for identity theft, financial fraud, and corporate espionage. The attack surface is particularly concerning as it affects core customer search functionality, making exploitation likely and potentially automated through reconnaissance efforts. The vulnerability demonstrates poor input validation practices and violates fundamental secure coding principles that should prevent sql injection attacks through proper parameterization and input sanitization.
Mitigation strategies for this vulnerability must address both immediate remediation and long-term architectural improvements to prevent similar issues. The primary fix involves implementing proper parameterized queries or prepared statements for all database interactions, ensuring that user input is never directly concatenated into sql commands. Input validation should be implemented at multiple layers including application-level filtering and database-level restrictions. The system should employ proper error handling that prevents sql error messages from revealing database structure information to attackers. Security measures should include regular code reviews focusing on sql injection vulnerabilities, implementation of web application firewalls, and database access controls that limit permissions to minimum required levels. Organizations should conduct comprehensive penetration testing to identify similar vulnerabilities across the application stack. The remediation process must also include updating the warranty tracking system to a patched version and implementing monitoring to detect potential exploitation attempts. This vulnerability highlights the importance of adhering to secure coding standards and maintaining regular security updates to protect against known sql injection threats. The incident underscores the necessity of comprehensive security training for development teams to prevent injection vulnerabilities in application code.
