The vulnerability identified as CVE-2015-2242 represents a critical SQL injection flaw affecting the Webshop hun 1.062S web application. This vulnerability exposes the system to remote code execution through improper input validation mechanisms that fail to sanitize user-supplied data before incorporating it into database queries. The flaw specifically impacts the index.php script which processes two distinct parameters: termid and nyelv_id, both of which are susceptible to malicious input manipulation. The vulnerability stems from the application's failure to implement proper parameterized queries or input sanitization techniques, creating an attack surface where malicious actors can inject arbitrary SQL commands directly into the database layer.
From a technical perspective, this vulnerability operates under the Common Weakness Enumeration framework as CWE-89, which categorizes SQL injection flaws as weaknesses in software that allows attackers to manipulate database queries through untrusted input. The attack vector requires remote access to the vulnerable web application, with attackers able to craft malicious payloads that exploit the parameter handling mechanisms in index.php. When the application processes the termid or nyelv_id parameters without proper validation or sanitization, the SQL query construction becomes vulnerable to injection attacks. This allows threat actors to bypass authentication mechanisms, extract sensitive data, modify database contents, or potentially escalate privileges within the affected system.
The operational impact of CVE-2015-2242 extends beyond simple data theft, as it provides attackers with the capability to execute arbitrary commands on the underlying database server. This vulnerability can result in complete system compromise, data loss, unauthorized access to sensitive customer information, and potential regulatory compliance violations. Organizations running affected versions of Webshop hun 1.062S face significant risk of unauthorized data access, system downtime, and reputational damage. The vulnerability's remote nature means that attackers do not require physical access to the system, making it particularly dangerous in environments where the web application is exposed to public networks. Furthermore, the impact can cascade through integrated systems, potentially affecting other applications that share the same database infrastructure.
Mitigation strategies for this vulnerability should focus on implementing proper input validation and parameterized queries to prevent SQL injection attacks. Organizations should immediately apply the vendor-supplied patches or updates to address the vulnerability, while also implementing web application firewalls to monitor and filter malicious traffic patterns. The implementation of proper input sanitization techniques, including the use of prepared statements and parameterized queries, should be enforced across all database interaction points. Additionally, security monitoring should be enhanced to detect unusual database query patterns that might indicate exploitation attempts. Regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other applications, while access controls should be reviewed to limit database privileges to the minimum required for application functionality. This vulnerability also highlights the importance of following secure coding practices and adhering to industry standards such as those outlined in the OWASP Top Ten project, which specifically addresses SQL injection as one of the most critical web application security risks.
