|
|
The uplay ActiveX component allows an attacker to execute any command line action.
|
|
User must sign in, unless auto-sign in is enabled and uplay must not already be
|
|
running. Due to the way the malicious executable is served (WebDAV), the module
|
|
must be run on port 80, so please make sure you have enough privilege to do that.
|
|
Ubisoft released patch 2.04 as of Mon 20th July.
