TITLE:
Alipay PTA Module ActiveX Control Code Execution Vulnerability

SECUNIA ADVISORY ID:
SA24063

VERIFY ADVISORY:
http://secunia.com/advisories/24063/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Alipay PTA Module ActiveX Control 2.x
http://secunia.com/product/13433/

DESCRIPTION:
cocoruder has discovered a vulnerability in Alipay PTA Module ActiveX
Control, which can be exploited by malicious people to compromise a
user's system.

The problem is that the Remove() method of the Alipay PTA Module
ActiveX Control (PTA.DLL) does not properly validate the argument
passed to it. This can be exploited to execute arbitrary code via a
specially crafted web site.

Successful exploitation requires that the user is e.g. tricked into
visiting a malicious web site.

The vulnerability is confirmed in version 2.4.2.471. Other versions
may also be affected.

SOLUTION:
Do not visit untrusted web sites, or delete the affected DLL
component.
