CVE-2018-11193

Vulnerability

Quest DR Series Disk Backup software versions before 4.0.3.1 are affected by a privilege escalation vulnerability (issue 5 of 6) [1]. The specific nature of the bug is not detailed in the available reference, but it allows an attacker to escalate privileges, potentially leading to arbitrary code execution.

Exploitation

An attacker with local access to the system may exploit this vulnerability by leveraging insufficient privilege management in the backup software. The exact exploitation steps are not publicly disclosed, but the vulnerability can be triggered without user interaction beyond initial access.

Impact

Successful exploitation allows an attacker to escalate privileges, possibly gaining administrative control over the affected system. This could lead to full compromise of the backup software and underlying operating system, resulting in data disclosure, modification, or denial of service.

Mitigation

The vulnerability is fixed in version 4.0.3.1. Users should upgrade to this version or later. No workaround has been published. The vendor has addressed the issue in the official release [1].
