It appears that Websense Triton Unified Security Center does not encrypt credentials stored within the appliance.
Details: When logged into the Websense Triton Unified Security Center with any permission level, it is possible to navigate to the “Log Database” or “User Directories” portions of the “Settings” module. In either section, it is possible to use Google Chrome, Microsoft Internet Explorer, Apple Safari or Mozilla Firefox to “Inspect Elements” within the page.
Password blocks are initially hashed within the page using the following form variable:
<input type=”password” id=”logDatabaseSettings:password” name =”logDatabaseSettings:password” maxlength=”50″ size=”21″>
However, due to issues within the form construction and hashing of password credentials, it is possible to change the string to the following and reload the page:
<input type=”text” id=”logDatabaseSettings:password” name =”logDatabaseSettings:password” maxlength=”50″ size=”21″>
The password credentials are presented in plain-text, along with the associated username.
Criticality: Websense Triton Unified Security Center requires elevated privileges to connect and authenticate users against Microsoft Active Directory. This is typically an “administration” level account. As the Websense Triton Unified Security Center is facilitated by users with varying levels of domain permissions, it is possible for a typical user to gain Domain Administrator-Level permissions on the domain. As no additional tools are needed to gain this information such as Metasploit, Nessus, CORE Impact or similar, it is unlikely that any Intrusion Detection Tools would create an alarm.
Recommendations: We were unable to replicate the vulnerability in Websense 7.8.x. Though a very recent release, we recommend that administrators upgrade as quickly as possible. You can also apply the available hotfix to your existing environment.
It is recommended that you coordinate with Websense on the download and proper installation of the hotfix. The official hotfix can be downloaded from the following address.
