Sensitive location information disclosure via log redaction issue in Apple platforms

IdentifiersCVE-2023-40442CWE-532· Insertion of Sensitive Information…

CVE-2023-40442 is an Apple privacy vulnerability in which an application may be able to read sensitive location information. According to the provided advisory text, the issue was caused by insufficient redaction of private data in log entries, allowing location-related data to remain accessible to apps. Apple states the issue was fixed by improving private data redaction for log entries. The vulnerability is addressed in macOS Big Sur 11.7.9, macOS Monterey 12.6.8, iOS 15.7.8, and iPadOS 15.7.8.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an application to access sensitive location information that should not have been exposed through system logging. The primary impact is privacy compromise and unauthorized disclosure of user location data to a local app.

Mitigation

If you can’t patch tonight, do this now.

Until patches can be applied, reduce exposure by limiting installation and execution of untrusted or unnecessary applications, especially on affected Apple devices, since the issue requires an app to read exposed log data. Restrict app deployment through MDM or enterprise controls where possible and minimize access to diagnostic/logging data. No vendor mitigation beyond updating is provided in the supplied content.

Remediation

Patch, then assume compromise.

Apply the vendor-provided updates that fix the issue: macOS Big Sur 11.7.9, macOS Monterey 12.6.8, iOS 15.7.8, and iPadOS 15.7.8, or later supported releases. Apple indicates the fix consists of improved private data redaction for log entries.
