CVE-2008-7154 in Docebo
Summary
by MITRE
Docebo 3.5.0.3 and earlier allows remote attackers to obtain sensitive information via a direct request to (1) class/class.conf_fw.php, (2) class.module/class.event_manager.php, (3) lib/lib.domxml5.php, or (4) menu/menu_over.php in doceboCore/; or (5) class/class.conf_cms.php, (6) lib/lib.compose.php, (7) modules/chat/teleskill.php, or (8) class/class.admin_menu_cms.php in doceboCms/; which reveals the installation path in an error message.

The vulnerability described in CVE-2008-7154 represents a critical information disclosure issue affecting Docebo versions 3.5.0.3 and earlier. This flaw exists within the doceboCore and doceboCms directories of the application, where specific PHP files generate error messages containing the absolute installation path of the system. The vulnerability stems from improper error handling mechanisms that fail to sanitize or suppress sensitive path information in error responses, allowing remote attackers to obtain detailed system configuration data through direct HTTP requests to vulnerable endpoints.
The technical implementation of this vulnerability involves several specific file paths within the Docebo application structure. The affected files include class/class.conf_fw.php, class.module/class.event_manager.php, lib/lib.domxml5.php, and menu/menu_over.php within the doceboCore directory, as well as class/class.conf_cms.php, lib/lib.compose.php, modules/chat/teleskill.php, and class/class.admin_menu_cms.php within the doceboCms directory. When these files encounter errors during processing, they output error messages that contain the complete server path where Docebo is installed, effectively leaking system information to unauthorized parties.
From an operational impact perspective, this vulnerability significantly compromises the security posture of affected systems by providing attackers with crucial reconnaissance data. The leaked installation paths enable adversaries to perform more sophisticated attacks such as path traversal exploits, directory listing attacks, or targeted exploitation of known vulnerabilities in specific system components. The information disclosure aligns with CWE-209, which addresses the improper handling of exceptions and errors that reveal sensitive information, and represents a classic example of how error handling can become a security vector rather than a defensive mechanism.
The vulnerability enables adversaries to leverage the disclosed path information for further exploitation activities, potentially leading to more severe consequences including privilege escalation, data breaches, or system compromise. Attackers can use this information to craft more targeted attacks against the application's underlying infrastructure, understand the system architecture, and identify potential weaknesses in the deployment environment. This type of information disclosure vulnerability is particularly dangerous as it provides attackers with foundational knowledge required for advanced persistent threats and facilitates the development of more sophisticated attack vectors.
Organizations should implement comprehensive mitigations including proper error handling procedures that prevent path information from being exposed in error messages, regular security updates to patch vulnerable versions, and the implementation of web application firewalls to monitor and filter suspicious requests to known vulnerable endpoints. The vulnerability demonstrates the critical importance of secure error handling practices and aligns with ATT&CK technique T1212, which covers the exploitation of information disclosure vulnerabilities to gain insights into system configurations and architecture. Regular security assessments and code reviews should focus on ensuring that error messages do not contain sensitive system information, and that all application components properly sanitize their output to prevent accidental information leakage.
