CVE-2018-25342 in Smartshop
Summary
by MITRE • 05/23/2026
Smartshop 1 contains a time-based blind SQL injection vulnerability that allows unauthenticated attackers to manipulate database queries by injecting SQL code through the 'searched' parameter in search.php. Attackers can send GET requests with malicious SQL payloads like SLEEP commands to extract sensitive database information including product details and system data.

Smartshop 1 suffers from a time-based blind sql injection vulnerability that represents a critical security flaw in the application's input validation mechanisms. This vulnerability resides within the search.php script where the 'searched' parameter is processed without proper sanitization or validation, creating an attack surface that allows unauthenticated threat actors to execute malicious sql commands. The vulnerability classifies under cwe-917 as a weak input validation that enables injection attacks, making it a prime target for automated exploitation tools and manual attackers seeking to compromise the database infrastructure. The time-based blind nature of this vulnerability means that attackers must rely on response delays to infer information from the database, typically employing sleep commands or similar time-delay techniques to extract data through boolean-based or time-based inference methods. The attack vector operates through simple get requests that append malicious sql payloads to the search parameter, allowing attackers to manipulate the underlying database queries and potentially extract sensitive information including product catalogs, user credentials, and system configuration details. This vulnerability directly impacts the confidentiality and integrity of the application's data layer, as unauthorized access to database contents can lead to complete system compromise and data exfiltration. The operational impact extends beyond simple data theft, as successful exploitation can enable attackers to escalate privileges, modify product listings, manipulate pricing information, and potentially establish persistent backdoors within the application environment. The vulnerability demonstrates a fundamental lack of proper sql query parameterization and input filtering, which violates core security principles outlined in the owasp top ten and represents a failure to implement defense-in-depth measures such as prepared statements and proper input validation. Organizations using this software face significant risk of data breaches and regulatory compliance violations, particularly in environments where sensitive customer information or financial data is stored within the affected database systems. Mitigation strategies must include immediate implementation of proper parameterized queries, input validation, and output encoding to prevent sql injection attacks, while also implementing web application firewalls and monitoring for suspicious sql injection patterns. The vulnerability also highlights the importance of regular security assessments and penetration testing to identify and remediate similar flaws before they can be exploited by malicious actors, as the ease of exploitation and potential impact make this a high-priority remediation item according to nist cybersecurity framework guidelines and mitre att&ck framework's initial access and execution tactics.
