"The version of Quest NetVault Backup Server running on the remote host is prior to 14.0.2. It is, therefore, affected
by multiple vulnerabilities, including:

  - A cross-site scripting vulnerability in the viewclient webpage that allows remote attackers to bypass
    authentication. User interaction is required. An attacker can leverage this in conjunction with other
    vulnerabilities to execute arbitrary code in the context of SYSTEM. (CVE-2026-7569)

  - A cross-site scripting vulnerability in the addclient3 webpage that allows remote attackers to bypass
    authentication. User interaction is required. An attacker can leverage this in conjunction with other
    vulnerabilities to execute arbitrary code in the context of SYSTEM. (CVE-2026-9780)

  - A command injection vulnerability in NVBULogDaemon JSON-RPC message processing that allows remote attackers to
    execute arbitrary code in the context of SYSTEM. Although authentication is required, the existing authentication
    mechanism can be bypassed. (CVE-2026-9787)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
