Exposure of Sensitive Information to an Unauthorized Actor
The Motorola PEBL U6 08.83.76R, the Motorola V600, and possibly the Motorola E398 and other Motorola P2K-based phones does not require pairing for a connection related to the Headset Audio Gateway service, which allows user-assisted remote attackers to obtain AT level access and view phonebook entries and saved SMS messages by connecting on Bluetooth channel 3 and tricking the user into pressing Grant, aka a "Blueline" attack. NOTE: while user-assisted, the attack is made more feasible because of a GUI misrepresentation issue that allows a default message to be replaced by an attacker-specified one.
CWE-200 - Information Exposure
An information exposure vulnerability is categorized as an information flow (IF) weakness, which can potentially allow unauthorized access to otherwise classified information in the application, such as confidential personal information (demographics, financials, health records, etc.), business secrets, and the application's internal environment.
