CVE-2024-28982Network attack vector

Authenticated denial of service via recursive entities

Published Jun 26, 2024 · Updated Sep 11, 2024

XML entity expansion in Pentaho Business Analytics Server before 10.1.0.0 and 9.3.0.7 allows remote authenticated users to interrupt the service. The Pentaho User Console ACL service parses DTDs without limiting nested or recursive entity expansion, allowing crafted XML to grow explosively in memory. A low-privileged account that can submit XML to the ACL endpoint can exhaust resources and interrupt availability; no data disclosure is reported.
