Description


Brian Dowling has reported a vulnerability in FlexNET Connect, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to the client retrieving and executing script code ("rules") from update servers in an insecure manner, which can be exploited to execute arbitrary code when a client checks for updates. This check can e.g. be triggered via the FLEXnet Connect ActiveX control when a user visits a specially crafted web page.

Successful exploitation requires e.g. a MitM (Man-in-the-Middle) or DNS spoofing attack.

This vulnerability is reported in Acresso FlexNET Connect, Macrovision FlexNET Connect, and InstallShield Update Service.


Solution:
Apply update or workaround.
