Summary

Vulnerability: Stored DOM XSS via Methods Management Fields (Global Persistent Payload Execution)

• Stored Cross-Site Scripting via Unsanitized Method Creation and Management Inputs
• Automatic Execution Across All Pages Where Method Is Rendered in Navigation

Description

The application fails to properly sanitize user-controlled input within the Methods Management functionality when creating or managing application methods/pages. Multiple input fields accept attacker-controlled JavaScript payloads that are stored server-side without sanitization or output encoding.

These stored values are later rendered directly into administrative interfaces and global navigation components without proper encoding, resulting in Stored DOM-Based Cross-Site Scripting (XSS).

Critically, because created methods are automatically rendered inside the system’s navigation/menu structure, the injected payload executes globally — meaning every page visited where the malicious method appears in the menu triggers the XSS payload automatically.

This significantly increases severity, as exploitation is not limited to a single view — it becomes a platform-wide persistent execution point.

Affected Functionality

• Methods creation functionality
• Methods management and listing functionality
• Administrative navigation rendering
• Permission-related UI rendering
• Global sidebar / menu rendering
• Storage and retrieval of method-related data

Affected Fields

The following fields accept unsanitized input and allow persistent JavaScript injection:

• Page Name
• Description
• Controller
• Method Name
• Seflink
• Page Order
• Symbol (FontAwesome 5)
• Permissions
• Parent Page
• Module

Attack Scenario

1. An attacker creates or edits a method.
2. The attacker injects a malicious XSS payload into any vulnerable field (e.g., Page Name).
3. The application stores the payload without sanitization or encoding. 4....
