Microsoft plugs hole in Exchange
The vulnerability revealed in Tuesday's advisory could be exploited to target people using the Web e-mail component for Exchange, called Outlook Web Access, Microsoft said. An attacker with an account on a company's Exchange server could create a script that, when run by an OWA user on the same server, would give access to the victim's e-mail boxes and information.
The flaw also allows the malicious programmer to place spoofed content, such as fake graphics and Web pages, in the server's cache of Web content.
The vulnerability is not easy to exploit, said Stephen Toulouse, a security program manager at Microsoft, citing several preconditions to making an attack work.
