  Possible Illegal File Access in Acuma's Acusend
------------------------------------------------------------------------

SUMMARY

Acusend is a leading report portal product from <http://www.acuma.co.uk>
Acuma. Acusend allows organizations to collect and collate information
from a diverse range of sources and present it via a uniform web
interface. Acusend is widely deployed in Government, Education and
Aerospace industries. A security vulnerability in the product allows users
to access reports they would otherwise not have access to (due to security
restrictions).

DETAILS

Vulnerable systems:
 * Acusend version 4

During a penetration test of a client's network, Sec-Tec has discovered
that it is possible for an authenticated user to access reports belonging
to other users if the full URL to the report is known. Although the full
URLs may appear to be random, certain factors such as time and date are
sometimes used as part of the URL structure, thereby greatly reducing
entropy. Release of this information has been withheld awaiting a
corrected version from Acuma.

Recommended Action:
The vendor states that the issue is rectified in the latest version.
