Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVE-2022-46898

High
9.8/10

Summary

An issue was discovered in Vocera Report Server and Voice Server 5.x through 5.8. There is Path Traversal via the "restore SQL data" filename. The Vocera Report Console contains a websocket function that allows for the restoration of the database from a ZIP archive that expects a SQL import file. The filename provided is not properly sanitized and allows for the inclusion of a path-traversal payload that can be used to escape the intended Vocera restoration directory. An attacker could exploit this vulnerability to point to a crafted ZIP archive that contains SQL commands that could be executed against the database.

CWE-22 - Path Traversal

Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
