Technical details
A directory traversal vulnerability exists within the restoreDB method of ATEN Unizon, specifically at the /rest/system/database/restore endpoint. The application fails to properly validate user-supplied file paths during database restoration operations. By providing a specially crafted path, an authenticated attacker can perform arbitrary file operations. This can be leveraged to achieve remote code execution in the security context of the SYSTEM account. The vulnerability was addressed in firmware version V2.7.264.001.
