Security readout for executives and security teams
Plain-English summary
CVE-2022-46902 is a path traversal flaw in Vocera Report Server and Voice Server 5.x through 5.8. A lower-privileged user could supply a crafted ZIP during database restore so files are written outside the intended temporary directory. Business impact is limited but real: unauthorized file write paths could affect confidentiality, integrity, and availability.
Executive priority
Treat this as a moderate operational risk, not an emergency based on the provided evidence. Prioritize confirmation of affected Vocera deployments and restrict administrative restore access while obtaining Stryker remediation guidance.
Technical view
The Vocera Report Console websocket database-restore function unzips an archive expected to contain a SQL import file. During extraction, ZIP entry paths are not properly checked for directory traversal, allowing writes to escape the intended temporary directory. CVSS is 6.3: network reachable, low complexity, privileges required, no user interaction, low C/I/A impact.
Likely exposure
Exposure is likely limited to organizations running Vocera Report Server or Voice Server 5.x through 5.8, especially where the Report Console restore function is reachable by authenticated users. The source bundle does not identify affected CPEs, deployment defaults, or fixed versions.
Exploitation context
The bundle does not show CISA KEV listing or active exploitation evidence. Exploitation requires network access and low privileges, with no user interaction. The issue is operationally meaningful because database restore functionality may run with file-system permissions beyond the requesting user.
Researcher notes
This is CWE-22 in archive extraction handling. The key validation points are product/version presence, authenticated access to the websocket restore path, and whether extraction normalizes and confines archive entry paths. The bundle lacks patch details, exploit observations, and precise product CPEs.
Mitigation direction
- Check Stryker/Vocera product security guidance for fixed versions or compensating controls.
- Restrict Report Console and database restore access to trusted administrators only.
- Limit network access to Vocera management interfaces using internal segmentation.
- Review restore workflow permissions and disable unnecessary restore capability where feasible.
- Monitor for unexpected files created under or outside Vocera temporary paths.
Validation and detection
- Inventory Vocera Report Server and Voice Server versions across the environment.
- Confirm whether any system runs version 5.x through 5.8.
- Verify who can access the Report Console database restore function.
- Review Stryker advisory details for applicability and remediation status.
- Check relevant logs for unusual restore attempts or archive processing errors.
