Acer LunchApp.APlunch ActiveX is prone to a remote code-execution vulnerability. Exploiting this issue allows remote attackers to execute arbitrary code in the context of applications using the affected ActiveX control and possibly to compromise affected computers. This issue affects Acer TravelMate 4150 and Acer Aspire 5600 notebooks with LunchApp.APlunch version 1.0.
Block external access at the network boundary, unless external parties require service.
If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits.
Run all software as a nonprivileged user with minimal access rights.
Run all client applications with the least privileges required. This will reduce the chance of this issue being exploited.
Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to detect and block attacks and anomalous activity. Since the webserver may log such requests, review its logs regularly.
Do not follow links provided by unknown or untrusted sources.
Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.
Since a successful exploit of this issue allows malicious code to execute in web clients, consider disabling support for script code and active content within the client browser. Note that this mitigation tactic might adversely affect legitimate websites that rely on the execution of browser-based script code.
The vendor released an advisory and fixes to address this issue. Please see the references for more information.
