Date: Thu, 10 Oct 2019 20:40:47 +0200 From: Egidio Romano <research@...mainsecurity.com> To: fulldisclosure@...lists.org Subject: [FD] [KIS-2019-09] SugarCRM <= 9.0.1 Multiple Phar Deserialization Vulnerabilities --------------------------------------------------------------- SugarCRM <= 9.0.1 Multiple Phar Deserialization Vulnerabilities --------------------------------------------------------------- [-] Software Link: https://www.sugarcrm.com [-] Affected Versions: Version 9.0.1 and prior versions, 8.0.3 and prior versions. [-] Vulnerabilities Description: 1) User input passed through the "backup_dir" parameter when handling the "Backups" action within the "Administration" module is not properly sanitized before being used in a file operation. This can be exploited by malicious users to inject arbitrary PHP objects into the application scope (PHP Object Injection via phar:// stream wrapper), allowing them to carry out a variety of attacks, such as executing arbitrary PHP code. Successful exploitation of this vulnerability requires a System Administrator account. 2) User input passed through the "file_name" parameter when handling the "step3" action within the "Import" module is not properly sanitized before being used in a file operation. This can be exploited by malicious users to inject arbitrary PHP objects into the application scope (PHP Object Injection via phar:// stream wrapper), allowing them to carry out a variety of attacks, such as executing arbitrary PHP code. 3) User input passed through the "importFile" parameter when handling the "RefreshMapping" action within the "Import" module is not properly sanitized before being used in a file operation. This can be exploited by malicious users to inject arbitrary PHP objects into the application scope (PHP Object Injection via phar:// stream wrapper), allowing them to carry out a variety of attacks, such as executing arbitrary PHP code. 4) User input passed through the "load_module_from_dir" parameter when handling the "UpgradeWizard" action within the "Administration" module is not properly sanitized before being used in a file operation. This can be exploited by malicious users to inject arbitrary PHP objects into the application scope (PHP Object Injection via phar:// stream wrapper), allowing them to carry out a variety of attacks, such as executing arbitrary PHP code. Successful exploitation of this vulnerability requires a System Administrator account. 5) User input passed through the "file_name" parameter when handling the "UploadFileCheck" action within the "UpgradeWizard" module is not properly sanitized before being used in a file operation. This can be exploited by malicious users to inject arbitrary PHP objects into the application scope (PHP Object Injection via phar:// stream wrapper), allowing them to carry out a variety of attacks, such as executing arbitrary PHP code. [-] Solution: Upgrade to version 9.0.2, 8.0.4, or later. [-] Disclosure Timeline: [07/02/2019] - Vendor notified [01/10/2019] - Versions 9.0.2 and 8.0.4 released [10/10/2019] - Publication of this advisory [-] Credits: Vulnerabilities discovered by Egidio Romano.
