Level Platforms Service Center Install Data HTTP Vulnerability
------------------------------------------------------------------------
SUMMARY
Level Platforms, Inc. (LPI) flagship product Managed Workplace Service
Center, which provides remote monitoring, reporting and alerting of device
& network status. The software is typically used by Managed Service
Providers and large IT departments. There is also a hosted version offered
through Ingram Micro.
LPI's software has two components, a Service Center (server) component,
and a Onsite Manager (client) component. The Service Center is typically
installed at a MSP's facility. The Service Center software sends &
receives data with one or more Onsite Manager software installations
(typically deployed at remote networks). The Service Center software also
provides a central console for management, monitoring, reporting and
alerting.
There exists at least one vulnerability in the Service Center software
that allows an attacker to remotely determine a wide variety of
potentially useful information via an HTTP URL.
DETAILS
Detailed Description:
A default install of the software handling the URL:
"http[s]://<SERVICE CENTER NAME>/About/SC_About.htm"
enumerates the following information without first checking to see if the
source of the command is authenticated (The <SERVICE CENTER NAME> is the
name that has been assigned to the Service Center website);
-Version
-Build
-Applied service packs
-Applied Hot Fixes
-The date and time each were installed.
Exploitation of this vulnerability provides an with attacker potentially
useful information that could be leveraged to attack the host, clients or
other resource to which they have access.
A Google search using the phrase "/About/SC_About.htm" enumerates
vulnerable systems.
No information has been provided to support any benefit achieved by making
this information publically available.
Vendor Response:
This issue was reported to LPI by email on February 1, 2008.
On February 5, 2008 the following reply was received; "Thank you for your
input. I have forwarded this email over to our development team for their
consideration. Regards,..."
On February 6, 2008 the following reply was received; "...Our development
team is aware is this particular issue, and should be addressing it, just
want to let you know that having access to your build/version number isn't
hazardous to your managed services
business..."
Our Recommendation:
1. There is no reason to give away the version/build number and every
reason to keep it confidential. Reduce the attack surface wherever
possible or practical.
2. Take steps to prevent publishing or exposing any unnecessary or
sensitive information that could be used to exploit your network.
3. Until the vulnerability is resolved by LPI;
a) Prevent or restrict IP level access to the Service Center website by
restricting access to trusted IP ranges, or through VPN's. Note that
preventing Onsite Manager access to the Service Center website will result
in loss of functionality.
b) Review the security settings of each web page within Service Center.
c) Disallow indexing of the Service Center site by search engines using
IP restrictions, robots.txt files or other measures
