The vulnerability CVE-2018-13447 represents a critical sql injection flaw in Dolibarr ERP/CRM version 7.0.3 specifically affecting the product/card.php endpoint. This vulnerability resides in the handling of the statut parameter which is processed without adequate input sanitization or parameterized query construction. The flaw allows remote attackers to inject malicious sql code directly through the web interface, bypassing normal authentication and authorization mechanisms. The vulnerability is classified under CWE-89 which specifically addresses sql injection vulnerabilities where untrusted data is incorporated into sql queries without proper escaping or validation. This weakness enables attackers to manipulate database queries and potentially gain unauthorized access to sensitive information, modify data, or execute arbitrary commands on the underlying database system. The impact extends beyond simple data theft as it can lead to complete system compromise and unauthorized administrative access.
The technical exploitation of this vulnerability occurs when an attacker submits a malicious statut parameter value to the product/card.php script. The application fails to properly validate or sanitize this input before incorporating it into sql statements that interact with the backend database. This allows attackers to craft sql payloads that can manipulate the database structure, extract sensitive information from tables, or even execute system commands if the database user has sufficient privileges. The vulnerability is particularly dangerous because it affects a core business functionality within the ERP/CRM system where users might have legitimate access to the product management features. This creates a scenario where an attacker could leverage a valid user session to perform sql injection attacks without requiring additional authentication. The attack surface is further expanded by the fact that this vulnerability affects a publicly accessible web endpoint that could be targeted by automated scanning tools.
The operational impact of this vulnerability is severe for organizations using Dolibarr ERP/CRM version 7.0.3 as it creates a significant risk of data breaches and system compromise. Attackers could extract confidential customer information, financial data, user credentials, and business records stored in the database. The vulnerability also poses risks to business continuity as unauthorized modifications to product data or customer records could disrupt normal business operations. Organizations may face regulatory compliance violations if sensitive data is compromised, particularly in industries governed by data protection regulations such as gdpr or hipaa. The vulnerability could also be exploited to establish persistent backdoors or to escalate privileges within the system, potentially leading to complete takeover of the ERP/CRM infrastructure. This threat is particularly concerning given that ERP systems typically contain comprehensive business data that is critical to organizational operations and competitive advantage.
Organizations should implement immediate mitigations including applying the official security patch released by Dolibarr developers for version 7.0.3 and subsequent versions. Input validation and parameterized queries should be implemented to prevent sql injection attacks, ensuring that all user-supplied data is properly sanitized before database interaction. Network segmentation and web application firewalls can provide additional layers of protection by monitoring and filtering malicious sql injection attempts. Regular security assessments and penetration testing should be conducted to identify similar vulnerabilities in other components of the ERP/CRM system. The vulnerability aligns with ATT&CK technique T1071.005 which describes application layer protocol manipulation, specifically targeting web application vulnerabilities. Organizations should also implement database activity monitoring to detect anomalous sql queries that might indicate exploitation attempts. Access controls should be reviewed to ensure that database users have minimal required privileges, following the principle of least privilege as recommended by security frameworks such as the mitre ATT&CK matrix. Regular security awareness training for administrators and developers can help prevent similar vulnerabilities from being introduced in future code development cycles.
