Microsoft Exchange Server OWA cross-site request forgery
| ms-owa-csrf (60164) |
Description:
Microsoft Exchange Server is vulnerable to cross-site request forgery, caused by improper validation of user-supplied input by the Outlook Web Access component. By persuading an authenticated user to visit a malicious Web site, a remote attacker could send a specially-crafted HTTP request to gain complete control of the mail account. An attacker could exploit this vulnerability to perform cross-site scripting attacks, Web cache poisoning, and other malicious activities.
