SugarCRM <= 13.0.1 (set_note_attachment) Unrestricted File Upload Vulnerability
• Software Link:
• 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.
