Arbitrary file upload via attacker-controlled model
Published May 3, 2026 · Updated May 3, 2026
Unrestricted upload in CRMEB Java 1.3.0 through 1.3.4 allows remote authenticated users to store arbitrary files through Admin Upload. UploadServiceImpl processes the attacker-controlled model argument without enforcing an allowed file-type policy before the Admin Upload operation writes the file. Administrative privileges are required, and public evidence demonstrates file upload but not subsequent execution.
