Synopsis

An installed browser is vulnerable to address bar spoofing.

Description

The remote host is using Opera - an alternative web browser.

This version of Opera is vulnerable to a security weakness that may permit malicious web pages to spoof address bar information.

This is reportedly possible through malicious use of the JavaScript 'unOnload' event handler when the browser is redirected to another page.

This issue could be exploited to spoof the domain of a malicious web page, potentially causing the user to trust the spoofed domain.

Solution

Install Opera 7.50 or later.
