An issue was discovered in certain Apple products. iOS before 11.1 is affected. Safari before 11.0.1 is affected. iCloud before 7.1 on Windows is affected. iTunes before 12.7.1 on Windows is affected. tvOS before 11.1 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.

Detection & IOCsextracted from sources · hover to see the quote
- →Trigger pattern involves setting innerHTML on a nearestViewportElement, calling document.execCommand('selectAll'), and manipulating SVG/DOM node insertion events (clippath, image, svg, details, button.autofocus, DOMNodeInserted) to cause a use-after-free in WebCore::PositionIterator::decrement() ↗
- →The use-after-free crash occurs in WebCore::PositionIterator::decrement() triggered via document.execCommand('selectAll') after DOM manipulation with SVG elements; look for heap-use-after-free crashes in WebCore at this call stack location ↗
- →PoC exploit uses DOMNodeInserted event listener combined with SVG appendChild operations and document.execCommand calls ('selectAll', 'fontName') to trigger the vulnerability; monitor for suspicious combinations of these DOM APIs in web content ↗
- →Exploitation involves document.execCommand('fontName') and button.autofocus manipulation alongside SVG DOM mutations; these combined API calls in a single page load are a behavioral indicator ↗
- ·The PoC was confirmed only on an ASan build of WebKit nightly; behavior on production builds may differ and crash signatures will not include ASan output ↗
- ·Affected products span multiple Apple platforms (iOS <11.1, Safari <11.0.1, iCloud for Windows <7.1, iTunes for Windows <12.7.1, tvOS <11.1); detection scope must cover all WebKit-based runtimes on these platforms ↗
