TITLE:
ByteHoard File Copy and Script Insertion Vulnerabilities

SECUNIA ADVISORY ID:
SA20304

VERIFY ADVISORY:
http://secunia.com/advisories/20304/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:
>From remote

SOFTWARE:
ByteHoard 2.x
http://secunia.com/product/10172/

DESCRIPTION:
Nomenumbra has discovered two vulnerabilities in ByteHoard, which can
be exploited by malicious people to manipulate sensitive information
and conduct script insertion attacks.

1) Input passed to the "infolder" parameter in index.php when copying
a file isn't properly verified, before it is used in a copy operation.
This can be exploited to overwrite other users' files.

2) Input passed to the "description" parameter in index.php when
editing the file description isn't properly sanitised before being
used. This can be exploited to inject arbitrary HTML and script code,
which will be executed in a user's browser session in context of an
affected site when the malicious user data is viewed.

The vulnerabilities have been confirmed in version 2.1 Delta. Prior
versions may also be affected.

SOLUTION:
Update to version 2.1 Epsilon.
