Introduction:
|
||
=============
|
||
Web-based access to your monitoring data. elproLOG MONITOR WebAccess enables you to reliably access your data from any computer
|
||

Details:
|
||
========
|
||
1.1
|
||
A remote blind SQL Injection web vulnerability is detected in the ELPRO elproLOG MONITOR WebAccess v2.1 Web-Application.
|
||
The SQL Injection vulnerability allows an attacker (remote) to execute/inject own SQL commands in the vulnerable
|
||
web-application database management system.
|
||
|
||
The sql injection vulnerability is located in the strend.php file. Remote attackers can inject own sql commands by
|
||
attacking via http GET method request the affected id parameter of the vulnerable strend.php file.
|
||
|
||
Exploitation of the sql injection vulnerabilities requires no or a low privileged application user account and no user interaction.
|
||
Successful exploitation of the vulnerability results in database management system & application compromise via remote sql injection.
|
||
|
||
|
||
Vulnerable Module(s):
|
||
[+] Trends
|
||
|
||
Vulnerable File(s):
|
||
[+] strend.php
|
||
|
||
Vulnerable Parameter(s):
|
||
[+] id
|
||
|
||
|
||
|
||
1.2
|
||
A non persistent input validation vulnerability is detected in the elproLOG MONITOR WebAccess v2.1 Web-Application.
|
||
The bug allows remote attackers to force client side browser requests with manipulated web application context or
|
||
cross site links.
|
||
|
||
|
||
The first cross site scripting web vulnerability is located in the sensorview.php module when processing to load
|
||
a manipulated data parameter via GET. The attacker provokes the exception-handling to catch the invalid data error
|
||
with the injected script code (client-side).
|
||
|
||
The secound cross site scripting web vulnerability is located in the strend.php module when processing to load
|
||
a manipulated name parameter via GET. The attacker provokes the exception-handling to catch the invalid trend id
|
||
error with the injected script code (client-side).
|
||
|
||
The vulnerability can be exploited by remote attackers without required application user account but with low or
|
||
medium required user interaction. Successful exploitation of the vulnerability results in client side session hijacking,
|
||
account take-over, client side phishing, client side external redirects and client side manipulation of module context.
|
||
|
||
|
||
Vulnerable Module(s):
|
||
[+] sensorview
|
||
[+] trends
|
||
|
||
Vulnerable File(s):
|
||
[+] sensorview.php
|
||
[+] strend.php
|
||
|
||
Vulnerable Parameter(s):
|
||
[+] data
|
||
[+] name
|
||
|
||
|
||
Proof of Concept:
|
||
=================
|
||
1.1 - SQL Injection
|
||
The remote sql injection web vulnerability can be exploited by remote attackers without privileged application user account or
|
||
user interaction. For demonstration or reproduce ...
|
||
|
||
PoC:
|
||
http://elpro.localhost:8080/elpro/strend.php?data=8331&id=1+1%27'[SQL INJECTION VULNERABILITY]--&name=1
|
||
|
||
|
||
|
||
1.2 - Client Side Cross Site Scripting
|
||
The client side cross site scripting web vulnerability can be exploited by remote attackers without privileged application user account or
|
||
user interaction. For demonstration or reproduce ...
|
||
|
||
|
||
PoC:
|
||
http://elpro.localhost:8080/elpro-demo/sensorview.php?data=ECOLOG-NET%20Testing-1%27%3Ciframe%20src=http://vuln-lab.com%20onload=alert%28document.cookie%29%3C
|
||
Exception: Group: ECOLOG-NET Testing->"<
|
||
|
||
|
||
PoC:
|
||
http://elpro.localhost:8080/elpro-demo/strend.php?data=8331&id=0&name=->"<%27%27%3Ciframe%20src=http://vuln-lab.com%20onload=alert%28document.cookie%29%3C
|
||
Exception: Trend: Error ->"<
|
||
|
||
|
||
Solution:
|
||
=========
|
||
1.1
|
||
The sql injection web vulnerability can be patched by using a secure statement around the id parameter value implementation.
|
||
Encode and parse the input or setup an own new exception-handling to prevent future executions of sql commands.
|
||
|
||
|
||
1.2
|
||
Parse and encode the vulnerable data and name parameters to fix the client-side cross site scripting web vulnerability.
|
||
Ensure that the parameters are secure encoded in all different section of the application modules.
|
||
|
||
|
||
Risk:
|
||
=====
|
||
1.1
|
||
The security risk of the remote sql injection web vulnerability is estimated as high(+).
|
||
|
||
1.2
|
||
The security risk of the client-side cross site scripting web vulnerabilities are estimated as low(+)|(-)medium.
