Version Summary:Cisco Digital Media Manager contains a vulnerability that could allow an unauthenticated, remote attacker to conduct an open redirect attack. Updates are not available.
 
 
Description
Cisco Digital Media Manager (DMM) contains a vulnerability that could allow an unauthenticated, remote attacker to cause the DMM to issue a redirect to an arbitrary third-party URL.

The vulnerability is due to an open redirect issue in the DMM login page. An attacker could exploit this vulnerability by crafting a specific URL pointing to the DMM login page with a parameter that could trigger the DMM to issue an HTTP redirect to a host under the control of the attacker.

Cisco has confirmed the vulnerability in a security notice; however, software updates are not available.
 
Warning Indicators
At the time this alert was first published, Cisco DMM Software version 5.3 was vulnerable. Later releases of Cisco DMM Software may also be vulnerable.
 
IntelliShield Analysis
To exploit this vulnerability, it is likely an attacker would need to access or control a host system that is able to communicate with the targeted device. In addition, the attacker would need to know the location of the device to point a crafted URL to the login page. Typically, these devices would be on trusted, internal networks behind firewalls. These access requirements decrease the likelihood of a successful exploit.
