MASTG-TEST-0297 Sensitive Data Exposure Through Logging APIs (iOS)

Platform: iOS
Weakness: MASWE-0005
Weakness in the numbering of the MASWE beta: MASWE-0001
Profiles: L1 (basic security), L2 (advanced security)
Type: static, code
Prerequisites: identify-sensitive-data
Knowledge: MASTG-KNOW-0101
Best practices: MASTG-BEST-0022

Overview

On the iOS platform, logging APIs like NSLog, NSAssert, NSCAssert, print, and printf can inadvertently lead to the leakage of sensitive information. Log messages are recorded in the console, and you can access them by using MASTG-TECH-0060. Although other apps on the device cannot read these logs, direct logging is generally discouraged due to its potential for data leakage.

This test uses static analysis to verify whether an app contains logging APIs that take sensitive data as input.

This test focuses on logged sensitive data. For tests specifically targeting implementation details exposed through logs, see MASTG-TEST-0358 and MASTG-TEST-0359.

Steps

Use MASTG-TECH-0058 to extract the relevant binaries from app package.
Use MASTG-TECH-0066 to look for the relevant APIs in the app binaries.

Observation

The output should include the location of logging functions or other relevant logging references. Check the decompiled code to verify whether they receive sensitive data as input.

Evaluation

The test case fails if the app contains implemented logging paths that log sensitive data.
