Vulnerability discovered:
User Account Enumeration and User Account Information Disclosure
Vulnerability impact:
Low - Remote user accounts can be ascertained, and then possibly used to further gain access to valid credentials.
Vulnerability information:
Most information in Squiz Matrix CMS, including users, are stored as entites called "assets". This includes user accounts. By enumerating all assets, it is possible to determine if the asset is a user account by viewing the web page of a given asset by looking for the asset name prepended by a "~" character. Furthermore, if a valid user account asset is found, under most conditions tested, it is possible to disclose the user's account's full name/description by looking at the user's asset offset by -2.
Example:
http://[target]/?a=1000
You do not have permission to access <i>~test</i>
http://[target]/?a=998
You do not have permission to access <i>Test Account</i>
Recommendation:
Upgrade to version 4.4.5 or 4.6.1
