Summary
o [CVE-2020-3136_su]
A vulnerability in the web-based management interface of Cisco Jabber Guest
could allow an unauthenticated, remote attacker to conduct a cross-site
scripting (XSS) attack against a user of the web-based management interface
of an affected device.
The vulnerability exists because the web-based management interface of the
affected device does not properly validate user-supplied input. An attacker
could exploit this vulnerability by persuading a user to click a malicious
link. A successful exploit could allow the attacker to execute arbitrary
script code in the context of the affected interface or to access
sensitive, browser-based information.
There are no workarounds that address this vulnerability.
