Dell EMC NetWorker Multiple Vulnerabilities (DSA-2021-104)

medium Nessus Plugin ID 150504

Synopsis

The remote Windows host has an application installed that is affected by multiple vulnerabilities.

Description

The version of Dell EMC NetWorker installed on the remote Windows host is prior to 19.4.0.2. It is, therefore, affected by multiple vulnerabilities:

- Dell EMC NetWorker 18.x, 19.1.x, 19.2.x, 19.3.x, 19.4 and 19.4.0.1, contains an Information Disclosure vulnerability. A local administrator of the gstd system may potentially exploit this vulnerability to read LDAP credentials from local logs and use the stolen credentials to make changes to the network domain. (CVE-2021-21558)

- Dell EMC NetWorker versions 18.x, 19.1.x, 19.2.x, 19.3.x, 19.4, and 19.4.0.1 contain an Improper Certificate Validation vulnerability in the client (NetWorker Management Console) components which uses SSL encrypted connection in order to communicate with the application server. An unauthenticated attacker in the same network collision domain as the NetWorker Management Console client could potentially exploit this vulnerability to perform man-in-the-middle attacks to intercept and tamper the traffic between the client and the application server. (CVE-2021-21559)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Dell EMC NetWorker 19.4.0.2 or later.
