Cross-Site Scripting in Apple Safari and Apple OS document processing

IdentifiersCVE-2023-32445CWE-79· Improper Neutralization of Input…

CVE-2023-32445 is an Apple vulnerability affecting Safari 16.6, watchOS 9.6, iOS 15.7.8 and iPadOS 15.7.8, tvOS 16.6, iOS 16.6 and iPadOS 16.6, and macOS Ventura 13.5 prior to the fix. Apple states that processing a document may lead to a cross-site scripting attack, and that the issue was addressed with improved checks. Based on the vendor description, the flaw is triggered during document processing and results in unintended script execution in a web context, consistent with a cross-site scripting condition. Apple did not provide further technical detail in the supplied content regarding the specific component, parser, or function involved.

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 may allow a cross-site scripting attack when a target processes a malicious document. In practical terms, this can enable execution of attacker-controlled script in the affected web context, which may permit actions such as session theft, unauthorized actions in the victim's browser context, content injection, or access to data available to that origin, subject to the browser's security model and the surrounding application context.

Mitigation

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

Until patches are applied, reduce exposure by avoiding processing untrusted or externally supplied documents on affected systems, especially documents received via email, messaging, downloads, or untrusted websites. Where operationally feasible, restrict document handling to trusted sources and use updated platforms/browsers for opening potentially untrusted content. The provided content does not include any Apple-recommended workaround beyond updating.

Remediation

Patch, then assume compromise.

Apply the vendor-provided updates that fix the issue: Safari 16.6, watchOS 9.6, iOS 15.7.8 and iPadOS 15.7.8, tvOS 16.6, iOS 16.6 and iPadOS 16.6, and macOS Ventura 13.5 or later, as applicable to the affected platform.
