Vulnerability Overview
The detection of Microsoft Exchange Web Services (EWS) indicates the use of Microsoft's advanced email and calendar service. While not a vulnerability in itself, the presence of EWS can inform potential attackers about the email infrastructure of a target organization, guiding further reconnaissance efforts.
Vulnerability Details
Microsoft Exchange Web Services (EWS) is an API that enables mail, calendar, and contacts access by client applications. It is detected when the /EWS/Exchange.asmx endpoint responds with specific headers or HTTP status codes indicative of EWS, such as X-Owa-Version headers or a 401 Unauthorized status, suggesting authentication is required for access.
Possible Effects
The exposure of EWS can lead to targeted phishing attacks or attempts to exploit known vulnerabilities in the Exchange server, potentially compromising sensitive corporate communications.
