Description

DataEase is an open source data visualization analysis tool. Versions 2.10.20 and below contain a SQL injection vulnerability in the dataset export functionality. The expressionTree parameter in POST /de2api/datasetTree/exportDataset is deserialized into a filtering object and passed to WhereTree2Str.transFilterTrees for SQL translation, where user-controlled values in "like" filter terms are directly concatenated into SQL fragments without sanitization. An attacker can inject arbitrary SQL commands by escaping the string literal in the filter value, enabling blind SQL injection through techniques such as time-based extraction of database information. This issue has been fixed in version 2.10.21.

• CWE-89Improper Neutralization of Special Elements used in an SQL CommandThe product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
