|Prevent cloning private issues by unauthorized users
Using a crafted request on bug_report_page.php (modifying the 'm_id'
parameter), any user with REPORTER access or above is able to view any
private issue's details (summary, description, steps to reproduce,
additional information) when cloning. By checking the 'Copy issue notes'
and 'Copy attachments' checkboxes and completing the clone operation,
this data also becomes public (except private notes).
Credits to Mustafa Hasan (strukt) firstname.lastname@example.org for the finding.
@atrol noted that the same vulnerability also existed in bug_report.php,
although in this case the information disclosure is limited to notes and
attachments (issue data itself does not become accessible).
Added an access level check, so that the operation now fails with an
Access Denied error in both cases.
