Command and Control
Sage X3 Unauthenticated Remote Command Execution (RCE) as SYSTEM in AdxDSrv.exe component. By editing the client side authentication request, an attacker can bypass credential validation. While exploiting this does require knowledge of the installation path, that information can be learned by exploiting CVE-2020-7387. This issue was fixed in AdxAdmin 93.2.53, which ships with updates for on-premises versions of Sage X3 including Version 9 (components shipped with Syracuse 220.127.116.11 and later), Sage X3 HR & Payroll Version 9 (those components that ship with Syracuse 18.104.22.168), Version 11 (components shipped with Syracuse 22.214.171.124 and later), and Version 12 (components shipped with Syracuse 126.96.36.199 and later) of Sage X3. Other on-premises versions of Sage X3 are unsupported by the vendor.
