Signature Detail

HTTP: Microsoft Exchange Outlook Web Access Cross Site Scripting

This signature detects attempts to exploit a known vulnerability in Microsoft Exchange Outlook Web Access (OWA). An attacker can send a malformed e-mail, which if accessed by a victim using OWA, causes the affected system to run a malicious script in the context of the user's session.

Extended Description

Microsoft Outlook Web Access (OWA) for Exchange Server is prone to a cross-site scripting vulnerability because the application fails to properly sanitize user-supplied input. An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal potentially sensitive information and launch other attacks.
