CVE-2006-2668 in Docebolms
Summary
by MITRE
Multiple PHP remote file inclusion vulnerabilities in Docebo LMS 2.05 allow remote attackers to execute arbitrary PHP code via a URL in the lang parameter to (1) modules/credits/business.php, (2) modules/credits/credits.php, or (3) modules/credits/help.php.

The CVE-2006-2668 vulnerability represents a critical remote code execution flaw affecting Docebo LMS version 2.05, specifically targeting the language parameter handling within credit module files. This vulnerability stems from improper input validation and sanitization mechanisms that fail to properly filter user-supplied data before incorporating it into the application's execution flow. The affected files modules/credits/business.php, modules/credits/credits.php, and modules/credits/help.php all contain insecure parameter handling that allows malicious actors to inject and execute arbitrary PHP code through crafted URLs passed in the lang parameter.
The technical exploitation of this vulnerability occurs through a classic remote file inclusion attack vector where an attacker crafts a malicious URL containing PHP code or references to external malicious scripts. When the application processes the lang parameter without proper validation, it directly includes and executes the malicious code, effectively granting remote attackers full control over the affected system. This type of vulnerability falls under CWE-98, which specifically addresses "Improper Control of Generation of Code ('Code Injection')" and aligns with ATT&CK technique T1190 for "Exploit Public-Facing Application" and T1059 for "Command and Scripting Interpreter."
The operational impact of this vulnerability is severe and multifaceted, potentially allowing attackers to establish persistent backdoors, exfiltrate sensitive data, modify application functionality, or use the compromised system as a launchpad for further attacks within the network. Given that Docebo LMS is an educational management system handling potentially sensitive student and institutional data, successful exploitation could result in data breaches, unauthorized access to academic records, and complete system compromise. The vulnerability affects the core authentication and authorization mechanisms of the platform, making it particularly dangerous for organizations relying on the system for critical educational operations.
Mitigation strategies for CVE-2006-2668 should prioritize immediate patching of the Docebo LMS application to the latest secure version that addresses the remote file inclusion vulnerability. Organizations should implement strict input validation and sanitization measures, particularly for all user-supplied parameters that are later used in include or require statements. The principle of least privilege should be enforced by configuring the application to use absolute paths for file includes rather than allowing relative or user-controlled paths. Network-level defenses including firewall rules, web application firewalls, and intrusion detection systems can provide additional layers of protection. Security monitoring should be enhanced to detect suspicious URL patterns and file inclusion attempts. Additionally, regular security assessments and code reviews should be conducted to identify similar vulnerabilities in other applications and ensure proper input validation practices are maintained throughout the software development lifecycle.
