Severity Level:
===============
Medium
Technical Details & Description:
================================
A non persistent cross site scripting web vulnerability has been discovered in
the official Cisco Newsroom online service web-application.
The vulnerability allows remote attackers to hijack website customer, moderator
or admin sessions data by client-side manipulated cross site requests.
The vulnerability is located in the `articleId` value of the cisco newsroom
service module. Remote attackers are able to inject own script codes to the
vulnerable GET method request of thenewsroom module. The attack vector of the
vulnerability is located on the client-side of the newsroom service
web-application.
The request method to inject the script code on client-side is `GET`. The
injection point of the issue is the vulnerable `articleId` value in the
newsroom and
the script code execution point is located in the exception-handling module
page. The exception-handling displays the input without secure encoding which
results
in the client-side script code execution.
The security risk of the non-persistent input validation web vulnerability is
estimated as medium with a cvss (common vulnerability scoring system) count of
3.4.
Exploitation of the client-side cross site scripting web vulnerability requires
low user interaction (click) and no privileged application user account.
Successful exploitation results in client-side account theft by hijacking,
client-side phishing, client-side external redirects and non-persistent
manipulation
of affected or connected service modules.
Request Method(s):
[+] GET
Vulnerable Service(s):
[+] Cisco Newsroom
Vulnerable Module(s):
[+] Newsroom
Vulnerable Parameter(s):
[+] articleId
Affected Section(s):
[+] Exception-handling (Cisco
Newsroom Webserver)
Proof of Concept (PoC):
=======================
The vulnerability can be exploited by remote attackers without privileged
application user account and with low or medium user interaction.
