From the CVE request :
Roland Becker (MantisBT developer) found that the delete_attachments_threshold permission was not being checked when a user attempted to delete an attachment from an issue. The more generic update_bug_threshold permission was being checked instead. MantisBT administrators may have been under the false impression that their configuration of the delete_attachments_threshold was successfully preventing unwanted users from deleting attachments.

The CVE identifier of CVE-2012-2692 has been assigned to this issue:
mantis-1.2.12-1.fc18 has been pushed to the Fedora 18 stable repository. If problems still persist, please make note of it in this bug report.

EPEL5 hasn't been touched since Dec 2010, and the package is technically orphaned. As a result I'm closing this bug as this issue is fixed in Fedora. The EPEL5 tracking bug #800667 will remain open until either mantis is dropped from EPEL or it is fixed.
