Vulnerability Description
Several remote code execution vulnerabilities have been reported in Microsoft Visual Basic. Visual Basic (VB) is an event-driven programming language that was created by Microsoft for building stand alone Windows-based programs. Developers can use it for quickly building GUI applications. A remote attacker could exploit this issue by convincing a user to visit a specially crafted HTML document or open a malicious web page. Successful exploitation could result in remote code execution on the target system once the malicious page is loaded.
Vulnerability Details
The vulnerabilities are due to a flaw is located in multiple ActiveX Controls of Visual Basic. To trigger these issues, an attacker can create a malicious web page that initiates vulnerable COM Objects. Successful exploitation of this vulnerability allows execution of arbitrary code on the vulnerable system.
