DataEase is an open source business intelligence and data visualization tool. Prior to version 2.10.12, because DB2 parameters are not filtered, a JNDI injection attack can be directly launched. JNDI triggers an AspectJWeaver deserialization attack, writing to various files. This vulnerability requires commons-collections 4.x and aspectjweaver-1.9.22.jar. The vulnerability has been fixed in version 2.10.12.
