Dank der modernsten Technik sind wir heute im Stande mit diesen  
Gegebenheiten auch für mehr Sicherheit zu sorgen.  
Mit unserer Technik haben Sie die Möglichkeit z.B. Personen, Tiere,  
Fahrzeuge, Container, Waren, Schiffe usw.  
Weltweit bis auf 2 Meter genau zu orten. Zusätzlich stehen Ihnen noch  
zahllose weitere Möglichkeiten zur Verfügung.  
Sie können Beispielsweise Online in unserem H.E.S.S. Control Center  
beobachten wie in Real time Ihr Kind morgens  
zur Schule geht oder Ihre Ware in Japan vom Schiff geladen wird. Dem  
Einsatzspektrum sind keine Grenzen gesetzt.  
Einsatzbeispiele:  
  
  
Für Privatkunden  
Kinderortung - z.B. auf dem Nachhauseweg Abends vom Training im Verein  
Senioren - z.B. für senile Ältere Personen die sich schnell Verlaufen  
Sportler - z.B. für Bergwanderer, Skifahrer oder Extremsportler die  
schnell in Gefahr kommen  
Kfz Ortung / Diebstahlschutz - z.B. zur Kfz widerbeschaffung nach  
einem Diebstahl  
Tiere - z.B. für Weidetiere oder Pferde  
  
Für Gewerbliche Kunden

=======================  
Remote  
  
  
Severity:  
=========  
Critical  
  
  
Details:  
========  
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:  
=================  
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  
URL=http://xxx.de/vemap.aspx?name=remove&gpasswd=mypasstest  
  
<center>  
<p><br><br>  
<div id="LOGIN" >  
<form action="" name="loginform">  
<INPUT TYPE="TEXT" NAME="user" VALUE="remove" CLASS="LOGINFORM">  
<INPUT TYPE="PASSWORD" NAME="passwort" Value="mypasstest" CLASS="LOGINFORM">  
<INPUT TYPE="BUTTON" NAME="Login" VALUE="Login" CLASS="LOGINBUTTON"  
ONCLICK="getPostData(document.loginform.user.value,document.loginform.passwort.value);"></form>  
  
  
  
1.3  
PoC:  
Username: 'or 1=1--  
Password: 'or 1=1--  
  
  
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.
