CVE-2014-1276

Vulnerability

IOKit HID Event in Apple iOS before 7.1 allows attackers to conduct user-action monitoring attacks against arbitrary apps via a crafted app that accesses an IOKit framework interface [1]. The vulnerability exists in the IOKit framework's handling of HID (Human Interface Device) events, where an app can monitor user input actions without proper authorization. Affected versions include iOS prior to 7.1 on iPhone 4 and later, iPod touch (5th generation) and later, and iPad 2 and later [1].

Exploitation

An attacker must convince a user to install a crafted app that accesses the IOKit framework interface [1]. No additional privileges or network access are required beyond the ability to run the malicious app on the device [1]. The app can then monitor user actions such as taps and gestures through the IOKit HID Event interface [1].

Impact

Successful exploitation allows the attacker's app to conduct monitoring of user actions against arbitrary apps installed on the device [1]. This can lead to disclosure of sensitive user input, including credentials or private communications, as the attacker can observe what the user is doing on the device [1]. The attacker achieves unauthorized access to user interaction data, compromising confidentiality [1].

Mitigation

The issue is fixed in iOS 7.1, which was released on March 10, 2014 [1]. Users should update their devices to iOS 7.1 or later via the Settings > General > Software Update mechanism [1]. No workaround is available for older versions [1].
