## Summary ### **Vulnerability: Stored DOM XSS via System Settings – Company Information (Same-Page Attribute Breakout & Persistent Payload Injection)** - Stored Cross-Site Scripting via Unsanitized Company Information Configuration Fields with Immediate Same-Page Execution ### Description The application fails to properly sanitize user-controlled input within **System Settings – Company Information**. Several administrative configuration fields accept attacker-controlled input that is stored server-side and later rendered without proper output encoding. Affected fields include, but are not limited to: 1. Company Name 2. Slogan 3. Company Phone 4. Company Mobile 5. Company Email 6. Google Maps iframe link 7. Company Logo and other media-related fields Unlike the public-facing landing page injection vulnerability, this issue executes directly on the same settings page. The injected payload breaks out of the HTML attribute context and is immediately interpreted by the browser when rendered, resulting in same-page DOM-based stored XSS. This represents different functionality and a separate vulnerability from public-facing rendering. ### Affected Functionality - System Settings –

What to do next
- vendor patch
The original advisory lists fixed boundaries 0.31.0.0 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. FIRST EPSS
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.
