Last Update Date: 8 May 2012 12:33 Release Date: 8 May 2012 5282 Views

RISK: Medium Risk

TYPE: Operating Systems - Mac OS

A security issue has been identified in Apple Mac OS X, which can be exploited by malicious people with physical access to bypass certain security restrictions.

The security issue is caused due to the debug switch being enabled within FileVault when using "Legacy FileVault". This may lead to users' password being saved in DEBUGLOG in plain text and can be exploited to read the password via FireWire target disk mode.

Successful exploitation requires that OS X is upgraded from an older version and uses the "Legacy FileVault" feature.
