DescriptionCVE.org

DataEase is an open source data visualization and analysis tool. Prior to 2.10.24, a bypass of the H2 zip protocol and file dropper fix allows an authenticated attacker to upload a zip archive disguised with a .ttf extension through FontManage.saveFile and then exploit it through the zip protocol to achieve remote code execution. This issue is fixed in version 2.10.24.

AnalysisAI

Remote code execution in DataEase before 2.10.24 allows an authenticated attacker to bypass the prior H2 zip-protocol and file-dropper hardening by uploading a ZIP archive masquerading as a font file (.ttf) via the FontManage.saveFile endpoint, then invoking the H2 database zip protocol against it to execute arbitrary code on the server. The flaw is a regression that defeats an earlier fix, and carries a CVSS 4.0 score of 8.7 (High). …
