CWE-94
Summary
o A vulnerability in the Cisco IP Phone 8800 Series Software could allow an
unauthenticated, remote attacker to conduct an arbitrary script injection
attack on an affected device.
The vulnerability exists because the software running on an affected device
insufficiently validates user-supplied data. An attacker could exploit this
vulnerability by persuading a user to click a malicious link provided to
the user or through the interface of an affected device. A successful
exploit could allow an attacker to execute arbitrary script code in the
context of the user interface or access sensitive system-based information,
which under normal circumstances should be prohibited.
There are no workarounds that address this vulnerability.
