The vulnerability CVE-2017-18260 represents a critical SQL injection flaw within Dolibarr ERP/CRM software affecting versions through 7.0.0. This vulnerability exists in the comm/propal/list.php script where multiple parameters are susceptible to malicious input manipulation. The specific parameters identified as vulnerable are viewstatut and propal_statut, which are also known as search_statut parameters. These parameters control the status filtering functionality within the commercial proposal listing interface, making them prime targets for exploitation by attackers seeking to manipulate database queries. The vulnerability stems from insufficient input validation and sanitization within the application's query construction logic, allowing attackers to inject malicious SQL commands that bypass normal authentication and authorization mechanisms.
The technical exploitation of this vulnerability occurs through manipulation of HTTP GET parameters passed to the comm/propal/list.php endpoint. When an attacker supplies crafted input to the viewstatut or propal_statut parameters, the application fails to properly escape or validate these inputs before incorporating them into SQL queries. This improper handling follows CWE-89 standards for SQL injection vulnerabilities, where user-supplied data is directly concatenated into database queries without adequate sanitization. The attack vector leverages the application's failure to implement prepared statements or proper parameterized queries, instead relying on string concatenation that makes the system vulnerable to malicious payload injection. The vulnerability is particularly concerning as it affects core business functionality within the ERP system, potentially allowing attackers to access sensitive commercial data, modify records, or even escalate privileges within the database.
The operational impact of CVE-2017-18260 extends beyond simple data theft, as it provides attackers with the capability to perform unauthorized database operations. Successful exploitation could enable attackers to extract confidential customer information, sales proposals, financial records, and other sensitive business data stored within the Dolibarr system. The vulnerability also poses risks of data manipulation, allowing attackers to alter commercial proposal statuses, modify pricing information, or corrupt database integrity. From an ATT&CK framework perspective, this vulnerability maps to T1071.005 Application Layer Protocol and T1190 Exploit Public-Facing Application, as it targets publicly accessible web interfaces. The attack could potentially lead to persistent access if attackers can establish backdoors or maintain control over the compromised system, especially since the vulnerability affects the core commercial proposal management functionality that likely remains active throughout business operations.
Mitigation strategies for CVE-2017-18260 should prioritize immediate patching of affected Dolibarr versions to 7.0.1 or later, as this release contains the necessary fixes for the SQL injection vulnerabilities. Organizations should implement input validation at multiple layers, including application-level filtering and database-level query parameterization. Network segmentation and web application firewalls can provide additional protection by monitoring and filtering malicious requests targeting the vulnerable parameters. Security monitoring should include detection of unusual parameter patterns in the comm/propal/list.php endpoint, particularly those containing SQL keywords or injection payloads. Regular security assessments and code reviews should be conducted to identify similar vulnerabilities in other application components, following the principle of defense in depth. The remediation process should also include comprehensive testing to ensure that the patch does not introduce regressions in functionality while maintaining the integrity of the commercial proposal management system. Organizations should consider implementing automated vulnerability scanning tools to continuously monitor for similar SQL injection vulnerabilities across their ERP infrastructure and related web applications.
