TITLE:
kandalf upper File Upload Security Issue
SECUNIA ADVISORY ID:
SA37946
VERIFY ADVISORY:
http://secunia.com/advisories/37946/
DESCRIPTION:
A security issue has been discovered in kandalf upper, which can be
exploited by malicious people to compromise a vulnerable system.
The security issue is caused due to the upper.php script improperly
validating uploaded files. This can be exploited to execute arbitrary
PHP code by uploading a malicious PHP script with multiple
extensions.
Successful exploitation of this vulnerability requires that Apache is
not configured to handle the mime-type for media files with an e.g.
"gif", "jpg", or "jpeg" extension.
The security issue is confirmed in version 0.1. Other versions may
also be affected.
SOLUTION:
Restrict access to the upper.php script (via e.g. via .htaccess).
