Dell NetWorker versions 19.5 and earlier contain 'Apache Tomcat' version disclosure vulnerability. A NetWorker server user with remote access to NetWorker clients may potentially exploit this vulnerability and may launch target-specific attacks.

Dell EMC Networker versions prior to 19.5 contain an Improper Authorization vulnerability. Any local malicious user with networker user privileges may exploit this vulnerability to upload malicious file to unauthorized locations and execute it.

Dell EMC NetWorker versions prior to 19.3.0.2 contain an improper authorization vulnerability. Certain remote users with low privileges may exploit this vulnerability to perform 'nsrmmdbd' operations in an unintended manner.

Dell EMC NetWorker versions prior to 19.3.0.2 contain an incorrect privilege assignment vulnerability. A non-LDAP remote user with low privileges may exploit this vulnerability to perform 'saveset' related operations in an unintended manner. The vulnerability is not exploitable by users authenticated via LDAP.

EMC NetWorker may potentially be vulnerable to an unauthenticated remote code execution vulnerability in the Networker Client execution service (nsrexecd) when oldauth authentication method is used. An unauthenticated remote attacker could send arbitrary commands via RPC service to be executed on the host system with the privileges of the nsrexecd service, which runs with administrative privileges.

Dell EMC NetWorker versions between 9.0 and 9.1.1.8 through 9.2.1.3, and the version 18.1.0.1 contain a Clear-Text authentication over network vulnerability in the Rabbit MQ Advanced Message Queuing Protocol (AMQP) component. User credentials are sent unencrypted to the remote AMQP service. An unauthenticated attacker in the same network collision domain, could potentially sniff the password from the network and use it to access the component using the privileges of the compromised user.

In Dell EMC NetWorker versions prior to 9.2.1.1, versions prior to 9.1.1.6, 9.0.x, and versions prior to 8.2.4.11, the 'nsrd' daemon causes a buffer overflow condition when handling certain messages. A remote unauthenticated attacker could potentially exploit this vulnerability to cause a denial of service to the users of NetWorker systems.
