1.1
A persistent input validation web vulnerability is detected in the official WebAssist PowerCMS PHP Web-Application.
The bug allows an attacker (remote) to implement/inject own malicious persistent script codes (application side).
The vulnerability is located in the `User Management` module when processing to request via POST method manipulated `first-
& lastname` parameters. Remote attackers can change the name of an user account to own script code to execute the malicious
context in the `Add/Edit` mode or main `User Management` listing.
Exploitation of the persistent web vulnerability requires low user interaction and a local low privileged web-application account.
Successful exploitation of the vulnerability can lead to persistent session hijacking (customers), account steal via persistent web
attacks, persistent phishing or persistent manipulation of module context.
Vulnerable Module(s):
[+] User Management - Add User
Vulnerable Parameter(s):
[+] Firstname
[+] Lastname
Affected Module(s):
[+] User Edit/Add Listing
[+] User Management Listing
2.1 - 2.2
Two client-side cross site scripting web vulnerabilities are detected in the official WebAssist PowerCMS PHP Web-Application.
The non-persistent cross site scripting web vulnerability allows an attacker to manipulate client side web application to browser requests.
The first cross site scripting vulnerability is located in the contents_results.php file when processing to request via GET method manipulated
s_Keyword search parameters. The malicious context gets executed on client-side of the application in the search results listing.
The secound cross site scripting web vulnerability is located in the load_content.php file when processing to request via GET method manipulated
contentTotal parameters. The malicious context gets executed on client-side of the application in the error id listing of the load_content.php file.
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 mmanipulation
of the vulnerable module context.
