Official description
The Lite UI of Apache ShardingSphere ElasticJob-UI allows an attacker to perform RCE by constructing a special JDBC URL of H2 database. This issue affects Apache ShardingSphere ElasticJob-UI version 3.0.1 and prior versions. This vulnerability has been fixed in ElasticJob-UI 3.0.2. The premise of this attack is that the attacker has obtained the account and password. Otherwise, the attacker cannot perform this attack.

The underlying weakness: Improper Control of Dynamically-Managed Code Resources
The product does not properly restrict reading from or writing to dynamically-managed code resources such as variables, objects, classes, attributes, functions, or executable instructions or statements.
How developers prevent this class of flaw
- For any externally-influenced input, check the input against an allowlist of acceptable values.
- Refactor the code so that it does not need to be dynamically managed.
