Summary

A vulnerability exists in the group processing functions of Cisco Email 
Security Appliance (ESA) and Cisco Content Security Management Appliance (SMA)
devices that are configured to use Microsoft Active Directory services as the
authentication database. This configuration could allow an unauthenticated, 
remote attacker to bypass security restrictions and be assigned a role that 
the attacker was not explicitly assigned.

The vulnerability is due to incorrect processing of group names retrieved from
a Microsoft Active Directory server. An attacker could exploit this 
vulnerability if the attacker belongs to a group with a name that contains a 
similar set of characters as the name of an authorized group. An exploit could
allow the attacker to access the device or obtain access to a role for which 
the attacker was not specifically authorized on the device.

What Is a Cisco Security Notice?

The Cisco Product Security Incident Response Team (PSIRT) publishes Cisco 
Security Notices to inform customers of low- to mid-level severity security 
issues involving Cisco products.

Customers who wish to upgrade to a software version that includes fixes for 
these issues should contact their normal support channels. Free software 
updates will not be provided for issues that are disclosed through a Cisco 
Security Notice.

Security Vulnerability Policy at

Customers Using Third-Party Support Organizations

Customers may have Cisco products that are provided or maintained through 
prior or existing agreements with third-party support organizations, such as 
Cisco Partners, authorized resellers, or service providers. For these 
products, customers should consult their service providers or support 
organizations to ensure that any applied workaround or fix is the most 
appropriate in the intended network before it is deployed.
