Discovery Status:
=================
Published


Affected Product(s):
====================
European Security Services
Product: GPS Tracking System 1.0


Exploitation Technique:
=======================
Remote


Severity Level:
===============
Critical


Technical Details & Description:
================================
1.1
An Integer Overflow vulnerability is detected on the gps tracking system of (EES) European Security Services.
The calender application module allows an attacker to crash the applikation service via integer overflow bug.

Vulnerable Module(s):
					[+] Calender

--- Exception Logs ---
System.Overflow: 
Arithmetic operation resulted in an overflow.
at Microsoft.VisualBasic.CompilerServices.IntegerType.FromString(String Value)
at findMe.showData.Page_Load(Object sender, EventArgs e)
at System.Web.UI.Control.OnLoad(EventArgs e)
at System.Web.UI.Control.LoadRecursive()
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)




1.2
Multiple persistent input validation vulnerabilities are detected on the gps tracking system of (EES) European Security Services.
The vulnerability allows an local low privileged user account to inject/implement malicious persistent script codes on application-side.
Successful exploitation of the vulnerability can result in session hijacking or content request manipulation.

Vulnerable Module(s): (Persistent)
					[+] Userdata Form allows
					[+] Group Administration & Track ID
					[+] User Password CSRF + Reset


1.2.1
Another vulnerability is located on the session handling of the gps tracking system of (EES) European Security Services. 
The passwords got transfered in plain via session cookie. Successful exploitation can result in session hijacking without high 
required user inter action.

Vulnerable Module(s): 
					[+] Session Handling


1.3
Attacker can bypass the auth of the login form. The vulnerability allows remote attackers to access the 
admin control panel without authorization.

Vulnerable Module(s): 
					[+] Login


Proof of Concept (PoC):
=======================
1.1

Reference(s):

File(s):   showdata.aspx
Param(s):  ?name=noacct&month=8&year=
Param(s):  ?name=noacct&month=


PoC: 
Insert the following example string on the calender month parameter ... -9999999999999999999999999999999


1.2

Note: To reproduce the persistent vulnerabilities inject/implement own java or html script code on the affected vulnerable input section.


1.2.1

PoC: 
Username: 'or 1=1--
Password: 'or 1=1--


Security Risk:
==============
1.1     The security risk of the  client-side arithmetic integer overflow web vulnerability is estimated as low.
1.2     The security risk of the multiple persistent web vulnerabilities are estimated as medium(+).
1.2.1  The security risk of the unsecure session handling (plain transfer) vulnerability is estimated as medium(+). 
1.3     The security risk of the login (auth) bypass vulnerability is estimated as critical.
