SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to versions 7.15.1 and 8.9.3, the `action_exportCustom` function in `modules/ModuleBuilder/controller.php` fails to properly neutralize path traversal sequences in the `$modules` and `$name` parameters. Both parameters later reach the `exportCustom` function in `modules/ModuleBuilder/MB/MBPackage.php` where they are both utilized in constructing s paths for file reading and writing.
As such, it is possible for a user with access to the ModuleBuilder module, generally an administrator, to craft a request that can copy the content of any readable directory on the underlying host into the web root, making them readable. As the `ModuleBuilder` module is part of both major versions 7 and 8, both current major versions are affected. This vulnerability allows an attacker to copy any readable directory into the web root.
This includes system files like the content of `/etc, or the root directory of the web server, potentially exposing secrets and environment variables. Versions 7.15.1 and 8.9.3 patch the issue.
