Some vulnerabilities have been discovered in Friendly Technologies fwDialerTechTool.dll ActiveX control, which can be exploited by malicious people to disclose sensitive information and compromise a user's system.
1) A boundary error exists within the "CreateURLShortcut()" method when handling an overly long parameter. This can be exploited to cause a buffer overflow when a user e.g. visits a malicious website.
Successful exploitation allows execution of arbitrary code.
2) The ActiveX control contains the insecure method "RunApp()", which allows launching of arbitrary applications with parameters when a user e.g. visits a malicious website.
3) The ActiveX control contains the insecure method "RegistryValue()", which allows reading and writing arbitrary registry keys when a user e.g. visits a malicious website.
The vulnerabilities are confirmed in version 188.8.131.52 of the ActiveX control as included with FriendlyPPPoE version 184.108.40.206. Other versions may also be affected.
Solution: Set the kill-bit for the affected ActiveX control.
