CVE-2011-4802 in Dolibarr
Summary
by MITRE
Multiple SQL injection vulnerabilities in Dolibarr 3.1.0 RC and probably earlier allow remote authenticated users to execute arbitrary SQL commands via the (1) sortfield, (2) sortorder, and (3) sall parameters to user/index.php and (b) user/group/index.php; the id parameter to (4) info.php, (5) perms.php, (6) param_ihm.php, (7) note.php, and (8) fiche.php in user/; and (9) rowid parameter to admin/boxes.php.

The vulnerability CVE-2011-4802 represents a critical SQL injection flaw affecting Dolibarr version 3.1.0 RC and potentially earlier releases. This vulnerability manifests across multiple endpoints within the Dolibarr web application, specifically targeting user management and administrative functions. The flaw allows authenticated remote attackers to manipulate database queries through carefully crafted input parameters, potentially leading to unauthorized data access, modification, or deletion. The affected parameters span across various user management interfaces including sortfield, sortorder, and sall in user/index.php, as well as id parameters in multiple files within the user/ directory and rowid in admin/boxes.php.
The technical exploitation of this vulnerability stems from inadequate input validation and parameter sanitization within the Dolibarr application's database interaction layers. When legitimate users submit requests containing malicious SQL payloads through the specified parameters, the application fails to properly escape or validate these inputs before incorporating them into database queries. This allows attackers to inject arbitrary SQL commands that execute with the privileges of the web application's database user. The vulnerability is classified as a CWE-89 SQL Injection, which represents one of the most prevalent and dangerous web application security flaws according to the CWE catalog. The attack surface is particularly concerning as it affects core user management functionality where attackers could potentially escalate privileges or access sensitive user data.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with the capability to manipulate the entire user management system. Successful exploitation could result in complete compromise of user accounts, unauthorized access to confidential business information, and potential lateral movement within the organization's network infrastructure. The vulnerability affects multiple administrative interfaces, meaning attackers could manipulate user permissions, modify system configurations, or gain access to sensitive organizational data stored in the Dolibarr database. This represents a significant risk for organizations relying on Dolibarr for business management, as the compromised system could serve as a foothold for broader attacks against the enterprise environment. The ATT&CK framework categorizes this as a Database Configuration Vulnerability, with potential for Privilege Escalation and Credential Access.
Mitigation strategies for CVE-2011-4802 require immediate patching of the Dolibarr application to the latest stable version containing the necessary security fixes. Organizations should implement proper input validation and parameter sanitization measures across all database interaction points, utilizing prepared statements and parameterized queries to prevent SQL injection attacks. Network segmentation and access controls should be enforced to limit the scope of potential exploitation, while monitoring systems should be deployed to detect anomalous database access patterns. Regular security assessments and vulnerability scanning should be conducted to identify similar issues in other applications. The vulnerability highlights the importance of maintaining up-to-date software versions and implementing robust input validation practices as recommended by security frameworks such as OWASP Top Ten and NIST guidelines for secure coding practices.
