CVE-2023-46237 in fogproject
Summary
by MITRE • 10/31/2023
FOG is a free open-source cloning/imaging/rescue suite/inventory management system. Prior to version 1.5.10, an endpoint intended to offer limited enumeration abilities to authenticated users was accessible to unauthenticated users. This enabled unauthenticated users to discover files and their respective paths that were visible to the Apache user group. Version 1.5.10 contains a patch for this issue.

The vulnerability identified as CVE-2023-46237 affects FOG, a comprehensive open-source system designed for cloning, imaging, rescue operations, and inventory management. This issue represents a critical access control flaw that undermines the security boundaries established within the application's architecture. The FOG system operates as a centralized management solution for networked computing environments, making it a potentially attractive target for adversaries seeking to gather intelligence about the underlying infrastructure and file system structure.
The technical flaw manifests in an improperly configured endpoint that was intended to provide limited enumeration capabilities to authenticated users only. However, due to inadequate access controls, this endpoint remained accessible to unauthenticated users who could exploit the vulnerability to discover files and their corresponding paths that were visible to the Apache user group. This misconfiguration effectively creates a directory traversal and information disclosure vulnerability that allows attackers to map the file system structure without requiring valid credentials. The vulnerability exists because the authentication check was either bypassed or incorrectly implemented, permitting unauthorized access to file enumeration functionality.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with valuable reconnaissance data that could be leveraged for more sophisticated attacks. Unauthenticated users can now enumerate files that the Apache process has access to, potentially revealing sensitive configuration files, backup data, or other system artifacts that could aid in further exploitation attempts. This information disclosure vulnerability aligns with CWE-200, which describes improper output neutralization for logs, and represents a classic case of insufficient access control. The exposure of file paths and potentially sensitive file structures creates opportunities for attackers to identify weak points in the system's overall security posture and plan subsequent attack vectors.
The vulnerability was addressed in version 1.5.10 of the FOG system through proper access control implementation. This patch ensures that the enumeration endpoint requires proper authentication before allowing access to file listing functionality, thereby restoring the intended security boundaries within the application. Organizations using FOG should immediately upgrade to version 1.5.10 or later to remediate this vulnerability. The fix aligns with ATT&CK technique T1213.002, which covers data from information repositories, as it prevents unauthorized access to file system information that could be used for further compromise. System administrators should also implement additional monitoring to detect potential exploitation attempts and verify that the patch has been properly applied across all instances of the FOG service.
