CyberRota Analysis
AI-GeneratedThe Document Merge Service is vulnerable to remote code execution due to server-side template injection, allowing attackers to execute arbitrary code within the server's context when processing XLSX templates. This vulnerability poses a significant risk as it grants attackers control over the server, potentially compromising sensitive data and system integrity. Organizations using versions prior to 9.1.0 should prioritize patching this vulnerability to mitigate the associated risks.

Original NVD Description
Document Merge Service is a document template merge service providing an API to manage templates and merge them with given data. Prior to version 9.1.0, a remote code execution (RCE) via server-side template injection (SSTI) allows for user supplied code to be executed in the server's context where it is executed as the document-merge-server user with the UID 901 thus giving an attacker considerable control over the container. The vulnerability is limited to XLSX templates, were the xltpl library uses a npn-sandboxed Jinja environment for the processing of the template. This issue has been patched in version 9.1.0.
