**Vulnerabilities:**Stack-based Buffer Overflow, Command Injection
This updated advisory is a follow-up to the original advisory titled ICSA-12-131-02 GE Intelligent Platforms Proficy HTML Help Vulnerabilities that was published June 27, 2012, on the NCCIC/ICS-CERT website.
By luring a user into visiting a malicious website, an attacker could exploit these vulnerabilities and execute arbitrary code on the client, or place or replace files on the client.
The following GE Intelligent Platforms products are affected:
A remote stack-based buffer overflow condition exists in the KeyHelp.ocx control because it fails to perform adequate boundary checks on user-supplied input.
CVE-2012-2515 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
The stack-based buffer overflow vulnerability has been identified, which may allow remote code execution.
CVE-2012-2516 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
Andrea Micalizzi working with Trend Microβs Zero Day Initiative reported these vulnerabilities to NCCIC.
GE Intelligent Platforms recommends that the KeyHelp.ocx ActiveX control be unregistered and deleted to eliminate these vulnerabilities. GE Intelligent Platforms has recommended specific control removal instructions for each of the affected products to ensure it continues to function properly once the control is removed.
