## Technical details

A SQL injection vulnerability exists within the NVBURASDevice component of Quest NetVault Backup during the processing of JSON-RPC messages. The root cause is a failure to properly validate user-supplied strings before they are used to construct SQL queries. While the vulnerability technically requires authentication, the existing authentication mechanism can be bypassed, making it accessible to remote attackers.
