iOSMobile App

Description

Sensitive data stored in keyboard cache is a vulnerability related to the usage of a platform, specifically for iOS and Mobile App. The vulnerability is classified under CWE-319: Cleartext Transmission of Sensitive Information. According to the OWASP Testing Guide, an attacker can easily extract sensitive data from the app cache, as the data is stored in plaintext. This can lead to the exposure of sensitive information such as passwords and other private data.

Risk

The risk of this vulnerability is high, as it can leak sensitive data without any effort. An attacker can gain access to personal information and use it maliciously. This can lead to identity theft and financial losses.

Solution

The best solution to fix this vulnerability is to secure the transmitted data. This can be done by using encryption or other methods to protect the data while it is being transmitted. Additionally, it is important to store the data in an encrypted format to prevent any malicious users from accessing it.

Example

// Store data securely
NSData *data = [NSData dataWithBytes: plaintext length: plaintextLen];
NSData *encryptedData = [data encryptWithKey:key];

The above example shows how to store data securely. The plaintext data is encrypted with a key to prevent unauthorized access.
