TITLE:
Pivot "refkey" File Deletion Vulnerability

SECUNIA ADVISORY ID:
SA34302

VERIFY ADVISORY:
http://secunia.com/advisories/34302/

DESCRIPTION:
A vulnerability has been discovered in Pivot, which can be exploited
by malicious people to delete certain files.

Input passed to the "refkey" parameter in
extensions/bbclone_tools/count.php is not properly sanitised before
being used to delete files. This can be exploited to delete files
with the permissions of the web server via directory traversal
sequences passed within the "refkey" parameter.

NOTE: Users with the "Advanced" user level are able to include and
execute uploaded PHP code via the "pivot_path" parameter in
extensions/bbclone_tools/getkey.php when
extensions/bbclone_tools/hr_conf.php can be deleted.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
