CVE-2021-1562
CVSS V2 Medium 4
CVSS V3 Medium 4.3
Description
A vulnerability in the XSI-Actions interface of Cisco BroadWorks Application Server could allow an authenticated, remote attacker to access sensitive information on an affected system. This vulnerability is due to improper input validation and authorization of specific commands that a user can execute within the XSI-Actions interface. An attacker could exploit this vulnerability by authenticating to an affected device and issuing a specific set of commands. A successful exploit could allow the attacker to join a Call Center instance and have calls that they do not have permissions to access distributed to them from the Call Center queue. At the time of publication, Cisco had not released updates that address this vulnerability for Cisco BroadWorks Application Server. However, firmware patches are available.
