Authenticated file disclosure via XML external entities
Published Apr 23, 2021 · Updated Sep 17, 2024
XML external entity injection in Avaya Callback Assist 4.0.x before 4.7.1.1 Patch 7 allows remote authenticated users to read system files. The administration component accepts XML containing external entity references and resolves them against host resources; Avaya has not identified the specific parser or endpoint. An authenticated network session is required, and the documented consequence is information disclosure rather than modification.
