Original Release Date: 2003-02-17 | Last Revised: 2003-02-21

Overview

Description

The Yahoo! Mobile Service enables users of handheld devices to take advantage of the same kinds of services Yahoo! Inc. offers to traditional desktop computing users (e.g. web browsing, email, etc.). A vulnerability in the Yahoo! Mobile service allows an attacker to view random queries from legitimate Yahoo! Mobile users. As a result, an attacker may be able to view privileged data, including any credentials that the victim had stored in recently viewed email messages.

Impact

An attacker can cause Yahoo! Mobile servers to return random web pages. Note that the attacker does not have any control over which pages are returned.

Solution

Yahoo! Inc. has fixed this vulnerability.
