Security Researcher Detected: You might have ended up here because your site vulnerability scanner found something interesting. Hi! I'm a security engineer and I'm having a good time interacting with the people and bots that are interested in information security.
You will hopefully find this site is well-secured and I'm not interested in being hacked. I'm interested in learning about how people try to hack me, though.
What is this endpoint?
owa/auth/logon.aspx
Microsoft Outlook Web Access
What an attacker could do
The OWA logon page exposes the Exchange credential prompt to brute force and phishing-style harvesting, and its markup/version strings reveal the precise build attackers need to select a matching mailbox-takeover exploit.
How to defend it
Apply MFA, account lockout, and login monitoring, strip version-revealing strings from the logon page, keep Exchange updated, and restrict external access through a reverse proxy or VPN.
