CRITICAL 9.8

DescriptionGitHub Advisory

Dataease is an open source data visualization analysis tool. Prior to version 2.10.19, DataEase uses the MD5 hash of the user’s password as the JWT signing secret. This deterministic secret derivation allows an attacker to brute-force the admin’s password by exploiting unmonitored API endpoints that verify JWT tokens. The vulnerability has been fixed in v2.10.19. No known workarounds are available.

AnalysisAI

DataEase data visualization tool prior to 2.10.19 uses MD5-hashed passwords without salting, allowing attackers to crack credentials and gain unauthorized access.

Technical ContextAI

DataEase < 2.10.19 stores passwords using unsalted MD5 hashes (CWE-522). MD5 is cryptographically broken for password storage — rainbow tables can crack most passwords instantly, and GPU-based cracking handles the rest.
