Available Updates

Zingbox Inspector, version 1.295 and later.

Workarounds and Mitigations

In the normal course of operation, Zingbox Inspector automatically updates its own software, and a fixed version of software has already been made available. No user action is required unless the software is unable to update itself. Customers still running affected versions of Zingbox Inspector software can mitigation this issue by updating to a patched version, or by disabling access to port 22 on the Zingbox Inspector by using a firewall.
