Exploitation vector: Network

Exploit availability: No

Vulnerable software:
Google Chrome
Client/Desktop applications / Web browsers

Description

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when processing data passed via vectors related to (1) the DOMWindow::clear function and use of a selection object, (2) the Object::GetRealNamedPropertyInPrototypeChain function and use of an __proto__ property, (3) the HTMLPlugInImageElement::allowedToLoadFrameURL function and use of a javascript: URL, (4) incorrect origins for XSLT-generated documents in the XSLTProcessor::createDocumentFromSource function, and (5) improper handling of synchronous frame loads in the ScriptController::executeIfJavaScriptURL function. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
