_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed AsiaInfo BSS version; versions `9.2.0` through `9.2.40` are affected

## Fix

## From the sources

AsiaInfo Business Support System (BSS) 9.2.0 through 9.2.40 does not correctly verify cryptographic signatures for JSON Web Tokens (JWT). A remote, unauthenticated attacker could forge a well-formed JWT without a valid signature and use it to execute privileged actions. Fixed in 9.2.41.
