Summary
* A vulnerability in the web-based management interface of Cisco Video
Surveillance Media Server could allow an unauthenticated, remote attacker
to cause a denial of service (DoS) of the web-based management interface of
an affected system.
The vulnerability is due to insufficient validation of user-supplied input
by the web-based management interface of the affected service. An attacker
could exploit this vulnerability by persuading a user of the interface to
click a malicious link. A successful exploit could allow the attacker to
cause the web-based management interface to become unreachable, resulting
in a DoS condition.
There are no workarounds that address this vulnerability.
