Microsoft Exchange Open Redirect Vulnerability


An open redirect vulnerability exists in Microsoft Exchange that could lead to spoofing. To exploit the vulnerability, an attacker could send a link that has a specially crafted URL, and convince the user to click the link. When an authenticated Exchange user clicks the link, the authenticated user's browser session could be redirected to a malicious site that is designed to impersonate a legitimate website. By doing so, the attacker could trick the user and potentially acquire sensitive information, such as the user's credentials.
