Cyberoam Unified Threat Management: Insecure Password Handling
Please find below the details of a vulnerability I discovered in
Cyberoam UTM device. The Vendor was notified, however I did not
receive any response from Vendor despite repeated email reminders.
SECURITY ADVISORY: cyberoam-utm-insecure-password-handling
Affected Software: Cyberoam CR50ia 10.01.0 build 678
Vulnerability: Insecure Password Handling
Release Date: Unreleased
"Cyberoam Unified Threat Management appliances offer assured security,
connectivity and productivity to Small Office-Home Office (SOHO) and
Remote Office-Branch Office (ROBO) users by allowing user
identity-based policy controls."
Cyberoam UTM integrates with Active Directory. In order to query data
from a configured AD, domain credentials are stored within the device.
These credentials are retrievable by an authenticated user.
Domain credentials are stored on the device and passed to web
clientson a diagnostic page (Identity --> Authentication -->
Authentication Server --> /Select Configured AD/ ). Authenticated
clients can thus easily access stored credentials.
A trivial check for this follows (replace cookie value):
curl -s -b "JSESSIONID=u2ur76lhy4qt" -H "Referer: blah"
The vulnerability allows a malicious user to access potentially
privileged domain credentials. Should default passwords not be
changed, then this is a trivial entry point onto a Windows domain.
Do not return stored credentials to the browser.
