Authentication bypass by capture-replay in Microsoft Exchange Server allows an authorized attacker to elevate privileges over a network.

Microsoft Exchange Server Elevation of Privilege Vulnerability

Improper neutralization of input during web page generation ('cross-site scripting') in Microsoft Exchange Server allows an authorized attacker to perform spoofing over a network.

Microsoft Exchange Server Security Feature Bypass Vulnerability

Heap-based buffer overflow in Microsoft Exchange Server allows an authorized attacker to execute code over a network.

Deserialization of untrusted data in Microsoft Exchange Server allows an authorized attacker to deny service over a network.

Improper control of resource identifiers ('resource injection') in Microsoft Exchange Server allows an authorized attacker to elevate privileges over a network.

Microsoft Exchange Server Information Disclosure Vulnerability

Microsoft Exchange Server Spoofing Vulnerability

Microsoft Exchange Server Remote Code Execution Vulnerability

A remote code execution vulnerability exists in Microsoft Exchange through the deserialization of metadata via PowerShell, aka 'Microsoft Exchange Remote Code Execution Vulnerability'.

A spoofing vulnerability exists in Microsoft Exchange Server when Outlook Web App (OWA) fails to properly handle web requests, aka 'Microsoft Exchange Spoofing Vulnerability'.

A denial of service vulnerability exists in Microsoft Exchange Server software when the software fails to properly handle objects in memory, aka 'Microsoft Exchange Denial of Service Vulnerability'.

An information disclosure vulnerability exists when Exchange allows creation of entities with Display Names having non-printable characters. An authenticated attacker could exploit this vulnerability by creating entities with invalid display names, which, when added to conversations, remain invisible. This security update addresses the issue by validating display names upon creation in Microsoft Exchange, and by rendering invalid display names correctly in Microsoft Outlook clients., aka 'Microsoft Exchange Information Disclosure Vulnerability'.

A cross-site-scripting (XSS) vulnerability exists when Microsoft Exchange Server does not properly sanitize a specially crafted web request to an affected Exchange server, aka 'Microsoft Exchange Server Spoofing Vulnerability'.
