CVE-2022-46902 — An issue was discovered in Vocera Report Server and Voice Server 5.x through 5.8

High CVSS 7.5

An issue was discovered in Vocera Report Server and Voice Server 5.x through 5.8. There is a Path Traversal for an Unzip operation. 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. During the unzip operation, the code takes file paths from the ZIP archive and writes them to a Vocera temporary directory. Unfortunately, the code does not properly check if the file paths include directory traversal payloads that would escape the intended destination.

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
