----------------------------------------------------------------- SuiteCRM <= 7.11.11 Multiple Phar Deserialization Vulnerabilities ----------------------------------------------------------------- [-] Software Link: https://suitecrm.com/ [-] Affected Versions: Version 7.11.11 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 "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. 4) 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. Successful exploitation of this vulnerability would require a System Administrator account. However, due to KIS-2020-04 it could be exploited by any user.
