ICS-CERT ADVISORY ICSA-13-022-01 - GE PROFICY REAL-TIME INFORMATION PORTAL 
INFORMATION DISCLOSURE VULNERABILTIES

January 22, 2013

OVERVIEW

This advisory provides mitigation details for multiple vulnerabilities that 
impact the GE Intelligent Platforms Proficy Real-Time Information Portal. 
General Electric (GE) has addressed two vulnerabilities in the GE Intelligent
Platforms Proficy Real-Time Information Portal. Exploitation of these 
vulnerabilities would result in information disclosure. The vulnerabilities 
can be exploited remotely. GE has produced two security advisories 
(GEIP12-14[a] and GEIP12-15[b]) available on the GE Intelligent Platforms 
support Web site to inform customers about these vulnerabilities.

AFFECTED PRODUCTS

GE Intelligent Platforms reports that the vulnerabilities affect the following
versions:

* Proficy Real-Time Information Portal: All versions.

IMPACT

CVE-2013-0651 is a security misconfiguration that, if exploited, could allow 
an unauthenticated remote attacker to retrieve sensitive configuration 
information such as system usernames and passwords for Portal data sources. 
The security misconfiguration is a default installation setting that can be 
subsequently changed.

CVE-2013-0652 is an information disclosure vulnerability that, if exploited, 
could allow an unauthenticated remote attacker to obtain a list of usernames 
for users of the Portal application and a limited amount of other technical 
information that could aid the attacker in conducting additional attacks.

Impact to individual organizations depends on many factors that are unique to
each organization. ICS-CERT recommends that organizations evaluate the impact
of these vulnerabilities based on their operational environment, architecture,
and product implementation.

BACKGROUND

According to GE, Proficy Real-Time Information Portal is a Web-based data 
visualization and reporting tool that is deployed across multiple industries 
worldwide.

VULNERABILITY CHARACTERIZATION

VULNERABILITY OVERVIEW

INFORMATION DISCLOSURE VULNERABILITY [c]

By default, the Portal installation creates files and folders in 
unauthenticated locations on the IIS or Apache Web server. An attacker can 
exploit this misconfiguration by making an HTTP GET request on Port 80/TCP to
retrieve configuration files and other sensitive information.

CVE-2013-0651[d] has been assigned to this vulnerability. A CVSS v2 base score
of 5.0 has been assigned; the CVSS vector string is 
(AV:N/AC:L/Au:N/C:P/I:N/A:N).[e]

INFORMATION DISCLOSURE VULNERABILITY [f]

Proficy Real-Time Information Portal exposes methods of a vulnerable class via
Java RMI. Even with Portal authentication enabled within the application, 
Portal unnecessarily exposes some of these methods and allows them to be 
called without authentication. An attacker can exploit the vulnerability by 
making an RMI call over Port 80/TCP to retrieve information.

CVE-2013-0652 [g] has been assigned to this vulnerability. A CVSS v2 base 
score of 5.0 has been assigned; the CVSS vector string is 
(AV:N/AC:L/Au:N/C:P/I:N/A:N).[h]

VULNERABILITY DETAILS

EXPLOITABILITY

These vulnerabilities could be exploited remotely.

EXISTENCE OF EXPLOIT

No known public exploits specifically target these vulnerabilities.

DIFFICULTY

An attacker with a low skill would be able to exploit these vulnerabilities.

MITIGATION

To mitigate these information disclosure vulnerabilities, GE recommends making
the following configuration changes:

* Disable Anonymous Authentication and Windows Authentication.

* Require authentication for all Portal users.

* Configure an SSL certificate to encrypt Portal application traffic.

Please see GE Intelligent Platforms Product Security Advisory GEIP12-14 and 
GEIP12-15 for detailed instructions.

ICS-CERT encourages asset owners to take additional defensive measures to 
protect against this and other cybersecurity risks.

* Minimize network exposure for all control system devices. Critical devices 
should not directly face the Internet.

* Locate control system networks and remote devices behind firewalls, and 
isolate them from the business network.

* When remote access is required, use secure methods, such as Virtual Private
Networks (VPNs), recognizing that VPN is only as secure as the connected 
devices.

ICS-CERT also provides a section for control systems security recommended 
practices on the US-CERT Web page. Several recommended practices are available
for reading and download, including Improving Industrial Control Systems 
Cybersecurity with Defense-in-Depth Strategies.[i] ICS-CERT reminds 
organizations to perform proper impact analysis and risk assessment prior to 
taking defensive measures.

Additional mitigation guidance and recommended practices are publicly 
available in the ICS-CERT Technical Information Paper, 
ICS-TIP-12-146-01ATargeted Cyber Intrusion Detection and Mitigation 
Strategies,[j] that is available for download from the ICS-CERT Web page 
(www.ics-cert.org).

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

DOCUMENT FAQ

What is an ICS-CERT Advisory? An ICS-CERT Advisory is intended to provide 
awareness or solicit feedback from critical infrastructure owners and 
operators concerning ongoing cyber events or activity with the potential to 
impact critical infrastructure computing networks.

When is vulnerability attribution provided to researchers? Attribution for 
vulnerability discovery is always provided to the vulnerability reporter 
unless the reporter notifies ICS-CERT that they wish to remain anonymous. 
ICS-CERT encourages researchers to coordinate vulnerability details before 
public release. The public release of vulnerability details prior to the 
development of proper mitigations may put industrial control systems and the 
public at avoidable risk.
