RELEASE DATE:
2010-08-05
DESCRIPTION:
A weakness has been reported in the Personal Classifieds plugin for
JomSocial, which can be exploited by malicious, local users to
manipulate certain data and potentially gain escalated privileges.

The weakness is caused due to the plugin setting insecure permissions
(777) for the "images/profclassifieds" folder and its subfolders. This
can be exploited to e.g. modify, create, or delete files contained in
the folders.

The weakness is reported in versions prior to 1.3.

SOLUTION:
Update to version 1.3, which sets permissions to 757. As this may
still be insecure, verify and set correct permissions manually.
