CVE-2011-3255

Description

CFNetwork in Apple iOS before 5 stores AppleID credentials in an unspecified file, which makes it easier for remote attackers to obtain sensitive information via a crafted application.

AI Insight

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

CFNetwork in iOS prior to 5 stores AppleID credentials in an unspecified file, enabling crafted apps to obtain sensitive information.

Vulnerability

The CFNetwork component in Apple iOS versions before 5 stores AppleID credentials in an unspecified file. This affects devices running iOS 4.x and earlier. The vulnerability is referenced in Apple's security advisory for the iOS 5 update [1].

Exploitation

An attacker would need to develop a crafted application and distribute it to a user running an affected version of iOS. Once the application runs on the device, it can access the file where AppleID credentials are stored, without the need for additional privileges or user interaction beyond installing the app.

Impact

Successful exploitation allows the malicious application to read stored AppleID credentials, leading to disclosure of the user's Apple ID and associated password. This could enable unauthorized access to the victim's iCloud account, purchases, and other Apple services.

Mitigation

Apple addressed this vulnerability in iOS 5, released on October 12, 2011. Users should update their devices to iOS 5 or later via iTunes to remediate the issue [1]. No workaround was provided for earlier iOS versions.
