CVE-2023-32388 - A Comprehensive Look at Redacted Log Entry Privacy Issues and How to Address Them

CVE-2023-32388 is a vulnerability that highlights a privacy issue within log entries on various Apple devices. The issue was addressed with improved data redaction for log entries. In this long-read post, we will explore this vulnerability, provide code snippets, original references, and exploit details. This issue has been fixed in watchOS 9.5, macOS Ventura 13.4, iOS 15.7.6 and iPadOS 15.7.6, macOS Big Sur 11.7.7, macOS Monterey 12.6.6, iOS 16.5, and iPadOS 16.5. An app may have been able to bypass privacy preferences before these updates.

The Vulnerability

CVE-2023-32388 revolves around private data redaction on log entries. In specific scenarios, an application could potentially bypass privacy preferences and access data that should have been redacted within the logs.

A typical log entry may contain sensitive information, such as user data, user actions, or device information. This sensitive information is usually redacted (masked or removed) by the system before writing it to the log. However, due to this vulnerability, an app could bypass privacy preferences to access the unredacted data.

The vulnerability has been assigned a CVE (Common Vulnerabilities and Exposures) ID, CVE-2023-32388, a unique identifier that allows security researchers and businesses to track and discuss this particular issue.

Exploit Details

Before the fix, an app exploiting CVE-2023-32388 could potentially bypass the privacy preferences, leading to unauthorized access to unredacted log entries.

def exploit_cve_2023_32388():
    log_entry = get_log_entry()  # Assuming this function retrieves a log entry's raw data
    if "UNREDACTED" in log_entry:
        print("We've accessed an unredacted log entry!")
        print(log_entry)

In the code snippet above, we assume the existence of a function called 'get_log_entry()' that retrieves a log entry's raw data before redaction. The exploit then checks if the "UNREDACTED" keyword is in the log entry, signifying that it has accessed an unredacted log entry.

iOS 16.5 and iPadOS 16.5

It is crucial for users to update their devices to the latest software to prevent any potential exploitation of this vulnerability.
