Description
An integer overflow issue exists in Apple products, addressed through improved input validation. This flaw could allow an application to execute arbitrary code with kernel privileges. Reports indicate that this issue was potentially exploited in the wild against iOS versions released before iOS 15.7. The vulnerability is related to an integer overflow in
mach make memory entry and vm copy. Exploitation involves a chain of events, starting with an invisible iMessage attachment that triggers a series of exploits to open a malicious URL containing obfuscated JavaScript and an encrypted payload. The JavaScript validator and binary validator are used to determine if the target device is a research environment. The vulnerability can be leveraged for full kernel read/write access, potentially enabling a deterministic exploit strategy. The offset and size are input variables that allow attackers to bypass restrictions and map memory outside the parent memory object. The Operation Triangulation campaign utilized this vulnerability, along with other techniques, to compromise devices and collect sensitive information, including microphone recordings, iCloud keychains, SQLite database data, and location data.Recommendations
