Description Marian Rehak 2019-06-28 08:24:23 UTC
The nested jar auto-extraction feature is vulnerable to "zip-slip" attacks, resulting in directory traversal. 

A specially crafted JAR file could use this flaw to write and overwrite arbitrary files. Combined with CVE-2019-10181, it can be used to rewriting the main Java application, which could possibly be used to escape the sandbox.
