CVE-2024-36079 in Vaultize
Summary
by MITRE • 05/25/2024
An issue was discovered in Vaultize 21.07.27. When uploading files, there is no check that the filename parameter is correct. As a result, a temporary file will be created outside the specified directory when the file is downloaded. To exploit this, an authenticated user would upload a file with an incorrect file name, and then download it.

The vulnerability identified as CVE-2024-36079 affects Vaultize version 21.07.27 and represents a critical file path manipulation flaw that stems from inadequate input validation during file upload operations. This issue manifests when the system fails to properly sanitize or validate the filename parameter provided during file uploads, creating a scenario where maliciously crafted filenames can bypass intended directory restrictions. The vulnerability resides in the file handling logic that processes user-supplied filenames without sufficient validation, allowing for path traversal behaviors that can result in unintended file system interactions.
The technical flaw in this vulnerability aligns with CWE-22, which describes improper limitation of a pathname to a restricted directory, commonly known as path traversal or directory traversal attacks. When an authenticated user uploads a file with a specially crafted filename containing directory traversal sequences such as "../" or similar constructs, the system creates temporary files outside the intended storage directory. This misconfiguration enables attackers to manipulate the file system location where temporary files are generated, potentially leading to unauthorized file creation in sensitive system directories or bypassing access controls that should restrict file operations to specific locations.
The operational impact of this vulnerability extends beyond simple file system manipulation and represents a significant security risk for organizations relying on Vaultize for data management and protection. An authenticated attacker with access to the system can exploit this weakness to create temporary files in arbitrary locations, potentially leading to privilege escalation scenarios where temporary files might be executed with elevated privileges. The vulnerability also enables potential information disclosure through the creation of files in unexpected locations, and could facilitate denial of service conditions by consuming system resources through unauthorized file creation in critical directories. Additionally, this flaw may allow attackers to circumvent security controls that depend on file location restrictions, undermining the integrity of the application's file handling mechanisms.
Mitigation strategies for CVE-2024-36079 should focus on implementing robust input validation and sanitization measures that prevent directory traversal sequences from being processed during file upload operations. Organizations should ensure that all filename parameters undergo strict validation to reject any input containing path traversal characters or sequences, while also implementing proper directory restriction mechanisms that enforce file storage within designated safe locations. The system should validate filenames against a whitelist of allowed characters and patterns, and implement proper sandboxing techniques that isolate file operations to predetermined directories without allowing external path manipulation. Additionally, security patches should be applied immediately to update Vaultize to versions that address this vulnerability, and organizations should conduct comprehensive security testing to identify any other potential path traversal vulnerabilities within their file handling systems. This vulnerability also highlights the importance of following secure coding practices and adhering to ATT&CK framework techniques related to privilege escalation and defense evasion through file system manipulation.
