This one is protected by the main SugarCRM.htaccess file, i.e. it doesn't allow access/execution for PHP files. However, this behaviourcan be overridden if a subdirectory contains another .htaccess file. So, an attacker canleverage the vulnerability to firstly upload a new .htaccess file and then to upload thePHP code they want to execute.[-] Proof of Concept:https://karmainsecurity.com/pocs/CVE-2023-35808.php[-] Solution:Upgrade to version 12.3.0, 12.0.3, 11.0.6, or later.[-] Disclosure Timeline:[14/02/2023] - Vendor notified[12/04/2023] - Fixed versions released[17/06/2023] - CVE number assigned[23/08/2023] - Publication of this advisory[-] CVE Reference:The Common Vulnerabilities and Exposures project (cve.mitre.org)has assigned the name CVE-2023-35808 to this vulnerability.[-] Credits:Vulnerability discovered by Egidio Romano.[-] Original Advisory:http://karmainsecurity.com/KIS-2023-05[-] Other References:https://support.sugarcrm.com/Resources/Security/sugarcrm-sa-2023-006/
