Rewterz Threat Advisory – CVE-2018-6973 and CVE-2018-3646 VMWare Workstation Player Multiple Vulnerabilities
August 16, 2018A tampering vulnerability exists when Microsoft Exchange Server fails to properly handle profile data. This may lead to unauthorized modification of system or user information.
IMPACT: NORMAL
PUBLISH DATE: 15-08-2018
OVERVIEW
A tampering security bypass vulnerability exists when Microsoft Exchange Server fails to properly handle profile data. In case of a successful attack, this vulnerability can be exploited by a remote authenticated user to modify a targeted user’s profile data or a system’s information.
ANALYSIS
The profile or system data can be modified by a remote authenticated user by sending specially crafted requests to the target Microsoft Exchange server.
This process exploits a security bypass vulnerability in the processing of profile data and modifies the target user’s profile data.
To exploit the vulnerability, an attacker would need to be authenticated on an affected Exchange Server. The attacker would then proceed to send the specially modified request to the server, targeting a specific user. The security update addresses the vulnerability by modifying how Microsoft Exchange Server handles profile data.
