CVE Reference(s):

Description


Some vulnerabilities have been reported in Awingsoft Winds3D Viewer, which can be exploited by malicious people to compromise a user's system.

1) An input validation error in the handling of the "GetURL()" method can be exploited to execute arbitrary programs on a system. In combination with the plug-in allowing arbitrary files to be downloaded to a system, this can be exploited to execute arbitrary code when a user e.g. visits a malicious website.

2) A boundary error in the handling of the "SceneUrl()" method can be exploited to cause a heap-based buffer overflow by supplying an overly long argument.

The vulnerabilities are reported in versions 3.0.0.5 and 3.5.0.0 Beta. Other versions may also be affected.

3) An error in the implementation of the "SceneUrl" property can be exploited to download and execute arbitrary files.

The vulnerability is confirmed in version 3.5.0.9 for Internet Explorer. Other versions may also be affected.

Successful exploitation of the vulnerabilities allows execution of arbitrary code.


Solution:
Disable the plug-in.
