Sage X3 Installation Pathname Disclosure. A specially crafted packet can elicit a response from the AdxDSrv.exe component that reveals the installation directory of the product. Note that this vulnerability can be combined with CVE-2020-7388 to achieve full RCE. This issue was fixed in AdxAdmin 93.2.53, which ships with updates for on-premises versions of Sage X3 Version 9 (components shipped with Syracuse 9.22.7.2 and later), Sage X3 HR & Payroll Version 9 (those components that ship with Syracuse 9.24.1.3), Version 11 (components shipped with Syracuse 11.25.2.6 and later), and Version 12 (components shipped with Syracuse 12.10.2.8 and later) of Sage X3. Other on-premises versions of Sage X3 are unsupported by the vendor.
