01. ###  Advisory Information ###

Title: Multiple Reflected XSS vulnerabilities in JAMon
Date published: 2013-01-23
Date of last update: 2013-01-23
Vendors contacted: JAMon  v 2.7
Discovered by: Christian Catalano
Severity: Low

02. ###  Vulnerability Information ###

CVE reference: CVE-2013-6235
CVSS v2 Base Score:  4.3
CVSS v2 Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
Component/s: JAMon  v 2.7
Class: Input Manipulation

03. ### Introduction ###

The Java Application Monitor (JAMon) is a free, simple, high 
performance, thread safe, Java API that allows developers to easily 
monitor production applications.

http://jamonapi.sourceforge.net

04. ### Vulnerability Description ###

Multiple Non-Persistent Cross-Site Scripting vulnerabilities have been 
identified in the JAMon web application.
JAMon  contains a flaw that allows multiple reflected cross-site 
scripting (XSS) attacks.
This flaw exists because certain  pages do not validate input before 
returning it to users.

+------------------------------+-------------------+
|-Vulnerable module(s)--------and----parameter(s)--|
+------------------------------+-------------------+
|mondetail.jsp --------------------ArraySQL--------|
|mondetail.jsp --------------------listenertype----|
|mondetail.jsp --------------------currentlistener-|
|jamonadmin.jsp -------------------ArraySQL--------|
|sql.jsp---------------------------ArraySQL--------|
|exceptions.jsp--------------------ArraySQL--------|
+------------------------------+-------------------+

05. ### Technical Description / Proof of Concept Code ###

05.01) Malicious Request ("ArraySQL" parameter):

The vulnerability is located in the ' Filter (optional) ' input field 
upon submission to the pages

http://localhost/jamon/mondetail.jsp
http://localhost/jamon/ jamonadmin.jsp
http://localhost/jamon/ sql.jsp
http://localhost/jamon/ exceptions.jsp

The application does not validate the 'ArraySQL' parameter upon 
submission to the *.jsp scripts.
The attacker  can inject  the malicious javascript code:

1-->1<ScRiPt >alert('XSS')</ScRiPt><!--

in the ' Filter (optional) ' input field and click on GO! button.

05.02) Malicious Request ("listenertype " parameter)
