DescriptionCVE.org

DataEase is an open source data visualization and analysis tool. Prior to 2.10.23, DataEase can be exploited by uploading payload.zip through the Excel upload API /datasource/upload, creating an H2 datasource that uses the zip: protocol, and executing an SQL dataset path where CalciteProvider.jdbcFetchResultField calls statement.executeQuery(), causing precompiled Java aliases in test.mv.db to execute arbitrary code. This issue is fixed in version 2.10.23.

AnalysisAI

Remote authenticated code execution in DataEase before 2.10.23 lets a low-privileged user abuse the Excel/datasource upload workflow to run arbitrary Java. By uploading a crafted payload.zip via /datasource/upload and defining an H2 datasource that references the archive through the zip: protocol, an attacker forces CalciteProvider.jdbcFetchResultField to execute a query that triggers precompiled Java aliases embedded in test.mv.db. …

Vulnerability AssessmentAI

Exploitation Requires an authenticated DataEase account with permission to reach /datasource/upload and to create datasources (CVSS PR:L - a low-privilege user, not an anonymous visitor). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuine priority rather than a paper high-CVSS issue: the attack yields arbitrary Java code execution over the network at low complexity, limited only by the need for an authenticated low-privilege account (CVSS 4.0 AV:N/AC:L/AT:N/PR:L/UI:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A user with a low-privilege DataEase account uploads a crafted payload.zip through the Excel/datasource upload API, then defines an H2 datasource whose JDBC URL points into that archive via the zip: protocol so H2 loads a malicious test.mv.db containing precompiled Java aliases. When the attacker runs an SQL dataset against that datasource, CalciteProvider.jdbcFetchResultField calls statement.executeQuery(), triggering the aliases and executing arbitrary code on the server. …
Remediation Vendor-released patch: upgrade to DataEase 2.10.23 or later, which introduces JdbcUrlSecurityPolicy and driver-class validation (commits 304104d70e27a97f8909981f56209edc117dc285 and a7bffa795cb0ca041dce0effe68479cf3bf13db1) to constrain which drivers and JDBC URLs a datasource may use; follow the advisory at https://github.com/dataease/dataease/security/advisories/GHSA-cjmg-jqmc-xj5v. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: identify all DataEase deployments and current versions, then restrict datasource upload and creation permissions to trusted administrators only-disable the feature entirely if business operations allow. …
