CVE-2010-1394

Vulnerability

A cross-site scripting (XSS) vulnerability exists in WebKit in Apple Safari before version 5.0 on Mac OS X 10.5 through 10.6 and Windows, and before version 4.1 on Mac OS X 10.4. The bug allows remote attackers to inject arbitrary web script or HTML via vectors involving HTML document fragments [2].

Exploitation

An attacker can exploit this vulnerability by crafting a malicious web page or HTML content that, when processed by the vulnerable WebKit engine, results in script injection. No special authentication or network position beyond the ability to serve content to the victim is required; the victim must simply load the crafted content in a vulnerable Safari browser [2][4].

Impact

Successful exploitation allows the attacker to execute arbitrary script or HTML in the context of the victim's browser session, leading to potential information disclosure, session hijacking, or other client-side attacks. The compromise occurs within the security context of the affected WebKit rendering engine [2].

Mitigation

Apple addressed this issue in Safari 5.0 and Safari 4.1, released on June 7, 2010 [2]. Users should update to Safari 5.0 (Mac OS X 10.5-10.6 and Windows) or Safari 4.1 (Mac OS X 10.4) or later. No workarounds are detailed in the available references.
