SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/30429/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, Manipulation of data, Exposure of system
information, DoS

WHERE:
>From remote

SOFTWARE:
DotNetNuke 3.x
http://secunia.com/product/5103/
DotNetNuke 4.x

DESCRIPTION:
Some vulnerabilities and a weakness have been reported in DotNetNuke,
which can be exploited by malicious people to disclose certain
information, cause a DoS (Denial of Service), manipulate certain
data, and bypass certain security restrictions.

1) The problem is that it is possible to trigger the install /
upgrade process, which can be exploited to cause a DoS by sending a
large number of specially crafted requests or to re-execute the
database scripts, resulting in data being overwritten or corrupted.

2) Errors in the logic for the UrlControl and the FileSystem API can
be exploited to upload certain safe files (e.g. txt, jpg, or gif
files) to restricted folders.

NOTE: "Safe" file extensions are defined in "Host Settings".

3) A weakness can be exploited to disclose the DotNetNuke version
number.

The vulnerabilities and weakness are reported in versions 3.0 through
4.8.2.

SOLUTION:
Update to version 4.8.3.
