Microsoft Exchange Server OWA could allow remote execution of code
| exchange-owa-execute-code (16583) |  High Risk |
Description:
Microsoft Exchange Server could allow a remote attacker to execute arbitrary code. OWA fails to properly validate input sent to an HTML redirection query before the input is sent to the browser. A remote attacker, who is authenticated, or who can log into OWA, can cause an arbitrary script to run with privileges of the victim. An attacker could also exploit this vulnerability to replace the Web browser cache and intermediate proxy cache with spoofed content, and possibly perform cross-site scripting attacks.
Consequences:
Gain Access
Remedy:
Apply the appropriate patch for your system, as listed in the Microsoft Security Bulletin MS04-026 . See References.
