Seth Fogie has reported a weakness in Spb Kiosks Engine, which potentially can be exploited by malicious, local users to bypass certain security restrictions.
The weakness is caused due to the product not being able to prevent users from using certain features in some programs to run other local programs via a hyperlink. In addition, users may also execute external programs via autorun when an external media like SD/CF card is inserted. This bypasses the security feature of the product.
Successful exploitation requires that autorun is enabled or the user is allowed to run an application that supports the execution of a program via hyperlink.
The weakness has been reported in version 220.127.116.11. Other versions may also be affected.
Note: It has also been reported that the product stores its passcode in cleartext in the registry.
Solution: Disable autorun on the device and do not allow users to run programs that can be used to execute other programs.
