AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

Office Viewer in iOS before 6 writes cleartext document data to a temporary file, allowing local users to bypass Data Protection or encryption.

Vulnerability

Office Viewer in Apple iOS versions prior to 6 writes document data in cleartext to a temporary file on the device. This behavior occurs when viewing documents through the Office Viewer component, and the temporary file is created without applying the intended Data Protection or encryption mechanisms. Affected versions include all iOS releases before 6. [1]

Exploitation

An attacker with local access to the device (e.g., a malicious app or someone with physical access) can read the temporary file containing the cleartext document data. No special privileges or user interaction beyond opening a document in Office Viewer are required. The attacker simply needs to locate and read the temporary file from the file system. [1]

Impact

Successful exploitation allows the attacker to bypass the document's intended Data Protection level or encryption state, leading to unauthorized disclosure of the document's contents. This compromises the confidentiality of sensitive information stored in documents viewed with Office Viewer. [1]

Mitigation

Apple addressed this issue in iOS 6, released on September 19, 2012. Users should update their devices to iOS 6 or later via iTunes. No workarounds are available for earlier versions. [1]
