Elazar Broad has discovered a vulnerability in Persits Software XUpload, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the ActiveX control (XUpload.ocx) when processing arguments passed to the "AddFolder()" method. This can be exploited to cause a stack-based buffer overflow via an overly long argument.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in version 220.127.116.11. Other versions may also be affected.
Solution: The vulnerability does not affect the latest 3.x version (18.104.22.168).
