Technical Details & Description:
================================
A client-side cross site scripting web vulnerability is detected in the
official ZAPms v1.42 Content Management System.
The non-persistent cross site scripting web vulnerability allows an attacker to
manipulate client side web application to browser GET method requests.
The vulnerability is located in the `name` value of the list GET method
request. Remote attackers are able to manipulate
the name value to execute client-side script code (application-side).
Exploitation of the vulnerability requires no privileged application user
account but low or medium user interaction. Successful exploitation of
the vulnerability results in session hijacking, client-side phishing,
client-side external redirects or malware loads and client-side manipulation
of the vulnerable module context.
Request Method(s):
[+] [GET]
Vulnerable Parameter(s):
[+] name ( rFmScr, eTt, newObj1 & name_new )
Proof of Concept (PoC):
=======================
The client-side cross site scripting web vulnerability can be exploited by
remote attackers without privileged application user account and
with low or medium user interaction. For demonstration or reproduce ...
