The SdcUser.TgConCtl ActiveX control in tgctlcm.dll in Consona Live Assistance, Dynamic Agent, and Subscriber Assistance does not properly restrict access to the HTTPDownloadFile, HTTPGetFile, Install, and RunCmd methods, which allows remote attackers to execute arbitrary programs via a URL in the url argument to (1) HTTPDownloadFile or (2) HTTPGetFile.
The SdcWebSecureBase interface in tgctlcm.dll in Consona Live Assistance, Dynamic Agent, and Subscriber Assistance allows remote attackers to bypass intended restrictions on ActiveX execution via "instantiation/free attacks."
The site-locking implementation in the SdcWebSecureBase interface in tgctlcm.dll in Consona Live Assistance, Dynamic Agent, and Subscriber Assistance relies on a list of server domain names to restrict execution of ActiveX controls, which makes it easier for man-in-the-middle attackers to execute arbitrary code via a DNS hijacking attack.
