Dataease: >> Dataease >> 2.10.18 Security Vulnerabilities
DataEase is an open source data visualization analysis tool. Versions 2.10.19 and below have inconsistent Locale handling between the JDBC URL validation logic and the H2 JDBC engine's internal parsing. DataEase uses String.toUpperCase() without specifying an explicit Locale, causing its security checks to rely on the JVM's default runtime locale, while H2 JDBC always normalizes URLs using Locale.ENGLISH. In Turkish locale environments (tr_TR), Java converts the lowercase letter i to İ (dotted capital I) instead of the standard I, so a malicious parameter like iNIT becomes İNIT in DataEase's filter (bypassing its blacklist) while H2 still correctly interprets it as INIT. This discrepancy allows attackers to smuggle dangerous JDBC parameters past DataEase's security validation, and the issue has been confirmed as exploitable in real DataEase deployment scenarios running under affected regional settings. The issue has been fixed in version 2.10.20.

Dataease is an open source data visualization analysis tool. Prior to 2.10.20, The table parameter for /de2api/datasource/previewData is directly concatenated into the SQL statement without any filtering or parameterization. Since tableName is a user-controllable string, attackers can inject malicious SQL statements by constructing malicious table names. This vulnerability is fixed in 2.10.20.

Dataease is an open source data visualization analysis tool. In DataEase 2.10.19 and earlier, the static resource upload interface allows SVG uploads. However, backend validation only checks whether the XML is parseable and whether the root node is svg. It does not sanitize active content such as onload/onerror event handlers or script-capable attributes. As a result, an attacker can upload a malicious SVG and then trigger script execution in a browser by visiting the exposed static resource URL, forming a full stored XSS exploitation chain. This vulnerability is fixed in 2.10.20.

Dataease is an open source data visualization analysis tool. Prior to 2.10.20, By controlling the IniFile parameter, an attacker can force the JDBC driver to load an attacker-controlled configuration file. This configuration file can inject dangerous JDBC properties, leading to remote code execution. The Redshift JDBC driver execution flow reaches a method named getJdbcIniFile. The getJdbcIniFile method implements an aggressive automatic configuration file discovery mechanism. If not explicitly restricted, it searches for a file named rsjdbc.ini. In a JDBC URL context, users can explicitly specify the configuration file via URL parameters, which allows arbitrary files on the server to be loaded as JDBC configuration files. Within the Redshift JDBC driver properties, the parameter IniFile is explicitly supported and used to load an external configuration file. This vulnerability is fixed in 2.10.20.

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.
