The vulnerability identified as CVE-2017-9435 affects Dolibarr ERP/CRM versions prior to 5.0.3, representing a critical security flaw that exposes the application to unauthorized data access and manipulation. This SQL injection vulnerability specifically targets the user/index.php endpoint, where the search_supervisor and search_statut parameters fail to properly sanitize user input before incorporating it into database queries. The flaw allows attackers to inject malicious SQL commands through these parameters, potentially enabling them to extract sensitive information, modify database records, or even escalate their privileges within the system.
The technical nature of this vulnerability aligns with CWE-89, which categorizes SQL injection as a persistent weakness in software applications that fail to properly validate and sanitize input data before executing database queries. The vulnerability operates by accepting user-supplied parameters without adequate sanitization or parameterization, allowing malicious actors to manipulate the SQL execution flow. When an attacker submits crafted input through the search_supervisor or search_statut parameters, the application processes these inputs directly within SQL statements, creating opportunities for unauthorized database access. This flaw represents a classic example of insufficient input validation and inadequate query parameterization, which are fundamental security practices that should prevent such injection attacks.
The operational impact of this vulnerability extends beyond simple data theft, as it can enable attackers to gain unauthorized access to sensitive business information including user credentials, financial records, customer data, and operational details. Depending on the database configuration and the attacker's level of access, this vulnerability could potentially allow for complete system compromise, data exfiltration, or even persistent backdoor establishment within the organization's infrastructure. Organizations using affected versions of Dolibarr ERP/CRM face significant risk of data breaches and regulatory compliance violations, particularly in environments where the system handles sensitive personal or financial information.
Mitigation strategies for CVE-2017-9435 primarily involve upgrading to Dolibarr ERP/CRM version 5.0.3 or later, which includes proper input validation and parameterized query implementations to prevent SQL injection attacks. Organizations should also implement additional defensive measures including input validation at multiple layers, regular security assessments of web applications, and monitoring for suspicious database access patterns. The ATT&CK framework categorizes this vulnerability under the technique of SQL Injection, which falls within the broader category of credential access and privilege escalation activities. Security teams should also consider implementing web application firewalls, database activity monitoring, and regular penetration testing to detect and prevent exploitation of similar vulnerabilities in other components of their IT infrastructure.
