Summary
o A vulnerability in the Security Assertion Markup Language (SAML) single
sign-on (SSO) interface of Cisco Unity Connection could allow an
unauthenticated, remote attacker to conduct a cross-site scripting (XSS)
attack against a user of the interface of an affected device.
The vulnerability is due to insufficient validation of user-supplied input
by the interface of an affected device. An attacker could exploit this
vulnerability by persuading a user of the interface to click a crafted
link. A successful exploit could allow the attacker to execute arbitrary
script code in the context of the affected interface or access sensitive,
browser-based information.
There are no workarounds that address this vulnerability.
