TITLE:
Persits Software XUpload "AddFolder()" Method Buffer Overflow

SECUNIA ADVISORY ID:
SA28145

VERIFY ADVISORY:
http://secunia.com/advisories/28145/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Persits Software XUpload 2.x
http://secunia.com/product/17042/

DESCRIPTION:
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 2.1.0.1. Other versions may
also be affected.

SOLUTION:
The vulnerability does not affect the latest 3.x version (3.0.0.4).

PROVIDED AND/OR DISCOVERED BY:
