Elazar Broad has discovered a vulnerability in Aurigma Image Uploader, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error in the Image Uploader Control ActiveX control when handling strings assigned to certain properties (e.g. "ExtractExif" and "ExtractIptc"). This can be exploited to cause a stack-based buffer overflow by assigning an overly long string to the affected properties.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in ImageUploader5.ocx version 5.0.15.0, ImageUploader4.ocx version 4.6.11.0 and reported in versions 4.6.17.0, 4.5.70.0, 4.5.126.0, and 5.0.10.0. Other versions may also be affected.

Solution
Update to version 4.7.0 or version 5.1.0.
