source listedECOSYSTEM: introduced 0; fixed 0.28.5.0
**Summary** A critical vulnerability has been identified in CI4MS that allows an authenticated user with file editor permissions to achieve Remote Code Execution (RCE). By leveraging the file creation and save endpoints, an attacker can upload and execute arbitrary PHP code on the server. **Vulnerability Details** The vulnerability exists in the /backend/fileeditor/createFile and /backend/fileeditor/save API endpoints. Unrestricted File Creation: The createFile endpoint allows users to create files with any extension (including .php) in web-accessible directories such as /public. Arbitrary Content Injection: The save endpoint allows users to write arbitrary content into the created files without sufficient server-side validation or sanitization. An attacker can combine these two flaws to create a PHP webshell and execute system-level commands, leading to a complete compromise of the web server. **Impact** Successful exploitation allows: Full access to the server's file system and databases. Execution of arbitrary OS commands. Permanent modification or deletion of application data. Steps to Reproduce Log in to an account with permissions to use the file editor. Create

What to do next
- vendor patch
The original advisory lists fixed boundaries 0.28.5.0 for ci4-cms-erp/ci4ms. Confirm the publisher’s latest guidance.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database via OSV
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. NIST National Vulnerability Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
