Date: Thu, 26 Oct 2023 17:25:44 +0200 From: Egidio Romano <research@...mainsecurity.com> To: Full Disclosure <fulldisclosure@...lists.org>, submissions@...ketstormsecurity.com 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: https://karmainsecurity.com/pocs/KIS-2023-11.php [-] Solution: Upgrade to version 13.0.2, 12.0.4, or later. [-] Disclosure Timeline: [23/04/2023] - Vendor notified [21/09/2023] - Fixed versions released [06/10/2023] - CVE identifier requested [26/10/2023] - Publication of this advisory [-] CVE Reference: The Common Vulnerabilities and Exposures project (cve.mitre.org) has not assigned a CVE identifier for this vulnerability.
