CVE-2017-3798
CWE-79
Summary
A cross-site scripting (XSS) filter bypass vulnerability in the web-based
management interface of Cisco Unified Communications Manager could allow an
unauthenticated, remote attacker to mount XSS attacks against a user of an
affected device.
The vulnerability is due to a failure to properly call XSS filter
subsystems when a URL contains a certain parameter. An attacker who can
persuade an authenticated user of an affected device to follow an
attacker-provided link or visit an attacker-controlled website could
exploit this vulnerability to execute arbitrary code in the context of the
affected site in the user's browser.
There are no workarounds that address this vulnerability.

Summary
A vulnerability in Cisco Unified Communications Manager could allow an
unauthenticated, remote attacker to conduct a cross-site scripting (XSS)
