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.
