Doc Text:
It was found that icedtea-web did not properly sanitize paths from <jar/> elements in JNLP files. An attacker could trick a victim into running a specially crafted application and use this flaw to upload arbitrary files to arbitrary locations in the context of the user.

Description Marian Rehak 2019-06-28 07:36:33 UTC 
While processing a JNLP file, the href attribute of a <jar/> element by Icedtea-Web is vulnerable to directory traversal.

<jar href="http://localhost/../../../../../XXX.any" version="2.0"/>
Considering the line above, the file XXX.any is saved out of the cache directory, overwriting the destination if it already exists. This is effectively an (over)write-what-where primitive on the filesystem, which could be used to execute arbitrary code (eg. via placing a file in the startup folder, overwriting .bashrc, or similar).
