The vulnerability CVE-2019-6296 represents a critical SQL injection flaw discovered in Cleanto version 5.0, specifically within the assets/lib/export_ajax.php component. This vulnerability exposes the application to unauthorized data access and potential system compromise through malicious manipulation of the id parameter. The flaw arises from insufficient input validation and improper parameter handling within the export functionality, creating an attack surface where malicious actors can inject arbitrary SQL commands into the database query execution process. Such vulnerabilities fall under the Common Weakness Enumeration category CWE-89, which specifically addresses SQL injection weaknesses in software applications.
The technical exploitation of this vulnerability occurs when an attacker submits a malformed id parameter value to the export_ajax.php endpoint. The application fails to properly sanitize or escape user-supplied input before incorporating it into database queries, allowing attackers to manipulate the SQL execution flow. This can result in unauthorized database access, data exfiltration, privilege escalation, or even complete system compromise depending on the database configuration and the attacker's level of access. The vulnerability is particularly dangerous because it targets a functionality that is likely used for legitimate data export operations, making it more difficult to detect and harder to prevent through traditional security monitoring approaches.
The operational impact of CVE-2019-6296 extends beyond immediate data breaches to encompass broader security implications for organizations using Cleanto 5.0. Attackers can leverage this vulnerability to extract sensitive customer information, financial data, or operational details stored within the application's database. The attack vector aligns with ATT&CK technique T1071.004 for application layer protocol manipulation and T1046 for network service scanning, as attackers typically probe for such vulnerabilities before executing more sophisticated attacks. Organizations may face regulatory compliance violations, financial losses, reputational damage, and potential legal consequences if sensitive data is compromised through this vulnerability.
Mitigation strategies for CVE-2019-6296 should prioritize immediate patching of the Cleanto 5.0 application to address the SQL injection vulnerability. Organizations should implement proper input validation and parameterized queries to prevent malicious SQL code execution, following the principle of least privilege for database connections and implementing comprehensive web application firewall rules. Additionally, security teams should conduct thorough penetration testing and code review processes to identify similar vulnerabilities in other application components. The remediation efforts should align with industry best practices outlined in OWASP Top 10 and NIST cybersecurity frameworks, ensuring that all database interactions properly sanitize user input and utilize prepared statements or parameterized queries to prevent SQL injection attacks. Regular security assessments and vulnerability management processes should be established to prevent similar issues in future software deployments.
