SuiteCRM has Relative Path Traversal via ModuleBuilder Modules ExportCustom Action

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.

SuiteCRM 安全漏洞

SuiteCRM是SuiteCRM团队的一个客户关系管理系统。 SuiteCRM 7.15.1之前版本和8.9.3之前版本存在安全漏洞，该漏洞源于modules/ModuleBuilder/controller.php中的action_exportCustom函数未能正确中和$modules和$name参数中的路径遍历序列，可能导致具有ModuleBuilder模块访问权限的用户将主机上任何可读目录的内容复制到Web根目录，从而泄露敏感信息。
