## Technical details

A SQL injection vulnerability exists within the processing of NVBULibrarySlot JSON-RPC messages in Quest NetVault Backup. The root cause is a lack of proper validation of user-supplied strings before they are used to construct SQL queries. While the affected function technically requires authentication, the existing authentication mechanism can be bypassed, making the flaw accessible to unauthenticated remote attackers. Successful exploitation allows for arbitrary code execution in the security context of the NETWORK SERVICE account. The vulnerability was addressed in version 14.0.2.
