Baser · Basercms · CVE-2018-18942
**Name of the Vulnerable Software and Affected Versions**
baserCMS versions prior to 4.1.4
**Description**
The issue allows remote attackers to execute arbitrary PHP code. This is achieved via the `admin/theme configs/form` data, specifically through the `ThemeConfig][logo` parameter in the `libBaserModelThemeConfig.php` file.
**Recommendations**
For versions prior to 4.1.4, update to version 4.1.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the `libBaserModelThemeConfig.php` file or disabling the `logo` parameter in the `admin/theme configs/form` data until a patch is applied.
