ICS-CERT received a report from GE Intelligent Platforms and the Zero Day Initiative (ZDI) concerning multiple memory corruption vulnerabilities in the GE Intelligent Platforms Proficy Plant Applications. These vulnerabilities were reported to ZDI by independent security researcher Luigi Auriemma.

If exploited, these vulnerabilities could allow an attacker to cause multiple Proficy services to crash, which may lead to arbitrary code execution. GE Intelligent Platforms has created patches to address these issues.

The following product and versions are affected:

• Proficy Plant Applications: Versions 5.0 and prior

IMPACT

Exploitation of these vulnerabilities could cause multiple Proficy services to crash and potentially allow an attacker to take control of a system running the affected software.

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 Plant Applications suite is an Operations Management software product that is deployed across multiple industries worldwide.

VULNERABILITY OVERVIEW

Proficy Plant Applications services process incoming TCP/IP traffic in a way that creates these memory corruption vulnerabilities. Exploitation of these vulnerabilities may cause Proficy services to crash or allow an attacker to gain control of the system.

PRRDS.EXE MEMORY CORRUPTION: Proficy Remote Data Service (PRRDS.exe) listens on Port 12299/TCP by default. CVE-2012-0230 has been assigned to this vulnerability.

PRLICENSEMGR.EXE MEMORY CORRUPTION: Proficy Server License Manager (PRLicenseMgr.exe) listens on Port 12401/TCP by default. CVE-2012-0231 has been assigned to this vulnerability.

EXPLOITABILITY: These vulnerabilities are remotely exploitable.

EXISTENCE OF EXPLOIT: No known public exploits specifically target these vulnerabilities.

DIFFICULTY: An attacker with a moderate skill level would be able to exploit these vulnerabilities.

MITIGATION

GE Intelligent Platforms recommends that customers apply product updates to supported Proficy Plant Applications Versions 5.0 and 4.4.1. Proficy Plant Applications customers using unsupported Versions 4.3.1, 4.2.3, 4.2.2, and 215.8 should contact GE Intelligent Platforms Support for assistance with obtaining and applying a patch.
