4) Description of Vulnerability

Secunia Research has discovered a security issue in Quicksilver
Forums, which can be exploited by malicious people to disclose
potentially sensitive information.

The database backup functionality stores the database backup with a
semi-predictable file name inside the web root. This can be exploited
to download the backup by guessing the file name.

NOTE: Additionally, database backup files are changed to world read-
and writable access permissions.

Do not use the database backup functionality. Restrict access to
existing backup files.
