CVE-2023-37497Network attack vector

Authenticated backend access via external entity resolution

Published Aug 3, 2023 · Updated Oct 17, 2024

XXE injection in HCL Unica Platform before 11.1.0.6 and 12.0 through 12.1.0 allows remote authenticated users to access backend resources. An exposed API sends arbitrary attacker-controlled XML to a backend parser without preventing external entity resolution. Access requires certain unspecified rights; HCL has not disclosed the API endpoint or the exact backend resources exposed.
