CVE-2021-21470 (GCVE-0-2021-21470)

Vulnerability from cvelistv5 – Published: 2021-01-12 14:41 – Updated: 2024-08-03 18:16

Summary

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. This occurs as logging service does not disable XML external entities when parsing configuration files and a successful exploit would result in limited impact on integrity and availability of the application.

Severity

3.6 (Low)
