Microsoft Exchange Server Remote Code Execution Vulnerability

This security issue affects Microsoft Exchange email servers. If an attacker who has a valid username and password for the email system exploits this vulnerability, they could take complete control of the Exchange server.

The problem exists in the web-based control panel that administrators use to manage Exchange. When certain types of data are sent to this control panel, the server doesn't properly check if that data is safe, allowing attackers to run their own malicious code.

This is particularly dangerous because many organizations rely on Exchange for their email, and a compromised Exchange server could lead to stolen emails, spreading of malware, or complete takeover of the email system.
