Summary

SQL Injection vulnerability in the NVBURemovableMedia component of Quest NetVault Backup allows remote attackers to execute arbitrary code. The flaw stems from improper validation of user-supplied data before using it in SQL queries, and the existing authentication mechanism can be bypassed.

Risk Assessment

An attacker can take control of the backup server in the context of the NETWORK SERVICE account, compromising the confidentiality, integrity, and availability of backup data.
