1. EXECUTIVE SUMMARY

  o CVSS v3 9.8
  o ATTENTION: Exploitable remotely/low skill level to exploit
  o Vendor: Qualcomm Life
  o Equipment: Capsule Datacaptor Terminal Server (DTS)
  o Vulnerability: Code Weakness

2. RISK EVALUATION

Successful exploitation of this vulnerability could allow an attacker to
execute unauthorized code to obtain administrator-level privileges on the
device.

3. TECHNICAL DETAILS

3.1 AFFECTED PRODUCTS

The following versions of Capsule Datacaptor Terminal Server (DTS), part of a
medical device information system, are affected:

  o Allegro RomPager embedded web server versions 4.01 through 4.34 included in
    Capsule DTS, all versions affected.

3.2 VULNERABILITY OVERVIEW

3.2.1    CODE CWE-17

This vulnerability allows an attacker to send a specially crafted HTTP cookie
to the web management portal to write arbitrary data to the device memory,
which may allow remote code execution.

CVE-2014-9222 has been assigned to this vulnerability. A CVSS v3 base score of
9.8 has been calculated; the CVSS vector string is
(AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

3.3 BACKGROUND

  o CRITICAL INFRASTRUCTURE SECTORS: Healthcare and Public Health
  o COUNTRIES/AREAS DEPLOYED: Worldwide
  o COMPANY HEADQUARTERS LOCATION: United States

3.4 RESEARCHER

Elad Luz of CyberMDX reported this vulnerability to NCCIC.

4. MITIGATIONS

Qualcomm Life reports this vulnerability does not affect any other Capsule
Technologies products.
Capsule Technologies has released a firmware update to remediate this
vulnerability on the "Single Board" version of the DTS, which was originally
released in 2009. Capsule Technologies strongly urges all users with a Single
Board version of the DTS to download the firmware from Capsule's customer
portal and apply it to the affected devices following standard patching
processes. Access to the customer portal can be found at the following
location:

https://customers.capsuletech.com

Due to technical limitations, the firmware update will remediate only the
Single Board version of the DTS, and will NOT remediate these other versions of
DTS:

  o Dual Board
  o Capsule Digi Connect ES converted to DTS
  o Capsule Digi Connect ES

Capsule recommends that users with any of these three versions of DTS disable
the embedded webserver to mitigate the vulnerability. The webserver is only
utilized for configuration during the initial deployment and is not necessary
for continued remote support of the device.

Additional information regarding the affected versions of the embedded Allegro
RomPager webserver included in Capsule DTS can be found at the following

NCCIC recommends users take defensive measures to minimize the risk of
exploitation of this vulnerability. Specifically, users should:

  o Minimize network exposure for all control system devices and/or systems,
    and ensure that they are not accessible from the Internet.
  o Locate control system networks and remote devices behind firewalls, and
    isolate them from the business network.
  o When remote access is required, use secure methods, such as Virtual Private
    Networks (VPNs), recognizing that VPNs may have vulnerabilities and should
    be updated to the most current version available. Also recognize that VPN
    is only as secure as the connected devices.

NCCIC reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.

NCCIC also provides a section for control systems security recommended
practices on the ICS-CERT web page. Several recommended practices are available
for reading and download, including Improving Industrial Control Systems
Cybersecurity with Defense-in-Depth Strategies.

Additional mitigation guidance and recommended practices are publicly available
on the ICS-CERT website in the Technical Information Paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies.

Organizations observing any suspected malicious activity should follow their
established internal procedures and report their findings to NCCIC for tracking
and correlation against other incidents.

No known public exploits specifically target this vulnerability.
