SA15300

VERIFY ADVISORY:
http://secunia.com/advisories/15300/

CRITICAL:
Moderately critical

IMPACT:
Exposure of sensitive information, DoS

WHERE:
>From remote

SOFTWARE:
ShowOff! Digital Media Software 1.x
http://secunia.com/product/5083/

DESCRIPTION:
dr_insane has discovered two vulnerabilities in ShowOff! Digital
Media Software, which can be exploited by malicious people to cause a
DoS (Denial of Service) and disclose sensitive information.

1) An input validation error in the request handling can be exploited
disclose the content of arbitrary files via directory traversal
attacks.

Examples:
http://[host]/ShowAlbum?ShowDetails&1&nocount&/../../../../../../../../../../[file]
http://[host]/ShowVideo?1&fullnocount&/../../../../../../../../../../[file]
http://[host]/ShowGraphic?/../../../../../../../../[file]

2) An error in the communication handling can be exploited to crash a
vulnerable service by sending a specially crafted malformed request to
port 8083.

Successful exploitation requires that file uploads are enabled (not
enabled in the default settings).

The vulnerabilities have been confirmed in version 1.5.4. Other
versions may also be affected.

SOLUTION:
1) Filter character sequences in a proxy server or firewall with URL
filtering capabilities.
2) Disable file uploads.
