Technical details
An absolute path traversal vulnerability (CWE-36) exists in the HTTP service of Navtor NavBox. The application fails to properly sanitize user-supplied path input, allowing unauthenticated remote attackers to bypass directory restrictions by submitting requests containing absolute filesystem paths. Successful exploitation enables the retrieval of arbitrary files from the host operating system, limited by the privileges of the service process. This can result in the exposure of sensitive OS configuration files and system information. The issue is addressed in version 4.14.1.2.
