TITLE

Cisco UCS Director and Cisco UCS Director Express for Big Data Input verification vulnerability in

Trust: 0.8

sources: JVNDB: JVNDB-2020-004411

DESCRIPTION

Multiple vulnerabilities in the REST API of Cisco UCS Director and Cisco UCS Director Express for Big Data may allow a remote attacker to bypass authentication or conduct directory traversal attacks on an affected device. For more information about these vulnerabilities, see the Details section of this advisory. (DoS) It may be put into a state. Authentication is not required to exploit this vulnerability.The specific flaw exists within the ScriptModuleAddJarPage method.
