This Metasploit module exploits a heap overflow found in InduSoft Web Studio <= 61.6.00.00 SP6. The overflow exists in the ISSymbol.ocx, and can be triggered with a long string argument for the InternationalSeparator() method of the ISSymbol control. This Metasploit modules uses the msvcr71.dll form the Java JRE6 to bypass ASLR.

User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within ISSymbol.ocx ActiveX component. The process performs insufficient bounds checking on user-supplied data passed in as the 'InternationalSeparator' parameter which results in a heap overflow. This vulnerability can be leveraged to execute code under the context of the user running the browser.
