CVE-2018-11148

Vulnerability

Quest DR Series Disk Backup software versions before 4.0.3.1 are vulnerable to a command injection flaw (issue 6 of 46). The vulnerability resides in the web management interface, where insufficient input validation allows an attacker to inject arbitrary operating system commands through crafted HTTP requests [1].

Exploitation

An attacker with network access to the web management interface can exploit this vulnerability without requiring authentication. By sending specially crafted HTTP requests containing shell metacharacters, the attacker can inject arbitrary commands that are executed on the underlying operating system [1].

Impact

Successful exploitation allows a remote, unauthenticated attacker to execute arbitrary commands with the privileges of the web service process. This can lead to full system compromise, including data exfiltration, modification, or destruction, and potentially further lateral movement within the network [1].

Mitigation

The vendor has addressed this vulnerability in Quest DR Series Disk Backup software version 4.0.3.1. Users should upgrade to this version or later. No workaround is documented in the available references [1].
