Subject: [FD] [KIS-2023-11] SugarCRM <= 13.0.1 (set_note_attachment)
 Unrestricted File Upload Vulnerability

-------------------------------------------------------------------------------
SugarCRM <= 13.0.1 (set_note_attachment) Unrestricted File Upload 
Vulnerability
-------------------------------------------------------------------------------

[-] Software Link:

https://www.sugarcrm.com

[-] Affected Versions:

Version 13.0.1 and prior versions.
Version 12.0.3 and prior versions.

[-] Vulnerability Description:

When handling the "set_note_attachment" SOAP call, the application 
allows uploading of
any kind of file into /upload/ directory. This one is protected by the 
main SugarCRM
.htaccess file, i.e. it doesn't allow access/execution of PHP files. 
However, this
behavior can be overridden if the subdirectory contains another 
.htaccess file.
So, an attacker can leverage the vulnerability to firstly upload a new 
.htaccess
file and then to upload the PHP code they want to execute.

[-] Proof of Concept:

Upgrade to version 13.0.2, 12.0.4, or later.
