Rewterz Threat Advisory – CVE-2019-1652 – Cisco RV320/RV325 Routers Command Injection Vulnerability
January 28, 2019

Rewterz Threat Advisory – Microsoft Exchange Sever 2013 CU21/ 2019/ 2016 CU11 API call privilege escalation

January 28, 2019

SEVERITY: High

 

 

CATEGORY: Vulnerability

 

 

ANALYSIS SUMMARY

 

 

Microsoft Exchange could allow a local authenticated attacker to gain elevated privileges on the system, caused by default high privileges in the Active Directory domain. By using an API call, an attacker could exploit this vulnerability to become a Domain Admin and gain elevated privileges on the system. The Exchange Windows Permissions group has WriteDacl access on the domain object in active directory, which enables any member of this group to modify the domain privileges, among which is the privilege to perform DCSync operations.
