CyberRota Analysis
AI-GeneratedWinter CMS versions prior to 1.2.13 are vulnerable due to an incomplete fix for a Twig sandbox escape, allowing authenticated backend users with template-editing permissions to bypass security restrictions. This flaw enables attackers to exploit method forwarding through Eloquent models, potentially leading to unauthorized database access, arbitrary SQL execution, and remote code execution via PHP injection. Organizations using affected versions should prioritize patching to mitigate the risk of exploitation.

Original NVD Description
Winter CMS versions before 1.2.13 contain an incomplete fix for a Twig sandbox escape vulnerability in System\\Twig\\SecurityPolicy that allows authenticated backend users with template-editing permissions to bypass sandbox restrictions. Attackers can exploit method forwarding through Eloquent models and query builders using methods like saveQuietly(), deleteQuietly(), increment(), decrement(), and newQuery() to read and modify arbitrary database records, execute arbitrary SQL, and achieve remote code execution by injecting PHP into template code sections.
