SAP EPM Add-in for Microsoft Office, version - 1010 and SAP EPM Add-in for SAP Analysis Office, version - 2.8, allows an authenticated attacker with user privileges to parse malicious XML files which could result in XXE-based attacks in applications that accept attacker-controlled XML configuration files.
