CVE-2015-5814

Vulnerability

A memory corruption issue exists in WebKit's JavaScriptCore, as used in Apple iOS before 9 and iTunes before 12.3. The vulnerability is triggered when processing maliciously crafted web content, leading to memory corruption. Affected versions: iOS versions prior to 9 and iTunes versions prior to 12.3 [1][3].

Exploitation

An attacker can exploit this vulnerability by enticing a user to visit a crafted website. No authentication or special network position is required; the attack is remote. The crafted website causes memory corruption in the JavaScriptCore engine, which can be leveraged for arbitrary code execution.

Impact

Successful exploitation allows a remote attacker to execute arbitrary code with the privileges of the affected application (e.g., MobileSafari on iOS or iTunes on Windows) or cause a denial of service via application crash. The impact includes full compromise of the application's sandbox and potential system-level access depending on the environment.

Mitigation

Apple addressed this vulnerability in iOS 9 [1] and iTunes 12.3 [3]. Users should update to these versions or later. No workarounds are documented. The vulnerability is not listed in CISA's Known Exploited Vulnerabilities catalog.
