TITLE

Cisco UCS Director and Cisco UCS Director Express for Big Data Vulnerability related to authority management in

Trust: 0.8

sources: JVNDB: JVNDB-2020-004413

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 processing of the userAPIDownloadFile API, which calls the downloadFile method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to disclose file contents in the context of root. Cisco UCS Director is a heterogeneous platform for Private Cloud Infrastructure as a Service (IaaS). A remote attacker could exploit this vulnerability by sending a request to a REST API endpoint to cause a denial of service
