CVE-2026-92187 in Foglight for Databases
Summary
by MITRE • 11/04/2026
Quest Foglight for Databases extractAndCreateUploadInfoList Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Quest Foglight for Databases. Authentication is required to exploit this vulnerability.
The specific flaw exists within the extractAndCreateUploadInfoList method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-29039.

The identified security flaw resides within Quest Foglight for Databases, specifically affecting the extractAndCreateUploadInfoList method which handles file upload operations. This component is responsible for processing user-supplied input to determine how uploaded files are stored and managed on the server infrastructure. The core technical deficiency lies in the insufficient validation of path components provided by the client during this process. When a user submits data intended for file storage, the application fails to adequately sanitize or normalize the directory traversal sequences embedded within the supplied filename or path string. This lack of rigorous input verification allows an attacker to manipulate the internal logic that determines the destination directory on the host system. By injecting specific characters such as dot-dot-slash sequences into the request parameters, the attacker can redirect file operations outside of the intended application sandbox and write files to arbitrary locations within the operating system's filesystem hierarchy.
This vulnerability is classified under CWE-22 Improper Limitation of a Pathname to a Restricted Directory which directly facilitates directory traversal attacks. The operational impact of this flaw is severe because it enables remote code execution with elevated privileges. Since Quest Foglight for Databases typically runs as a service on the underlying operating system, successful exploitation allows an authenticated attacker to execute arbitrary commands in the context of the SYSTEM account or equivalent high-privilege user depending on the deployment configuration. This level of access grants complete control over the affected host, permitting the installation of malware, creation of backdoors, exfiltration of sensitive database credentials and configuration data stored within the Foglight environment, and lateral movement to other systems on the network. The requirement for authentication means that while this is not an unauthenticated remote code execution vector, it remains a critical threat as many enterprise environments may have weak credential policies or exposed management interfaces accessible from internal networks where attackers often operate after initial perimeter breaches.
From a tactical perspective, this vulnerability aligns with ATT&CK techniques related to Command and Scripting Interpreter for executing arbitrary commands and File and Directory Information Discovery if the attacker uses the traversal capability to map out sensitive directories before deploying payloads. The ability to write files to arbitrary locations also relates to persistence mechanisms where attackers can place web shells or scheduled tasks that survive system reboots. To mitigate this risk, organizations must ensure they are running a patched version of Quest Foglight for Databases as provided by the vendor which addresses the input validation logic within the extractAndCreateUploadInfoList method. In addition to applying software updates, administrators should enforce strict network segmentation policies to limit access to the management interface only from trusted administrative subnets. Implementing web application firewalls with rules specifically designed to detect and block directory traversal patterns can provide an additional layer of defense against exploitation attempts. Regular vulnerability scanning and penetration testing focused on file upload functionalities are recommended to identify similar weaknesses in other components of the Foglight suite or related integrations that may share similar coding practices regarding path handling.
