info:
  name: System Dashboard < 2.8.10 - Cross-Site Scripting
  author: ritikchaddha
  severity: medium
  description: |
    The System Dashboard WordPress plugin before 2.8.10 does not sanitize and escape some parameters, which could allow administrators in multisite WordPress configurations to perform Cross-Site Scripting attacks through header injection, specifically in the X-Forwarded-For header.
  impact: |
    Authenticated administrators in multisite WordPress configurations can inject malicious JavaScript through X-Forwarded-For header to execute attacks against other WordPress users.
  remediation: |
    Update the System Dashboard plugin to version 2.8.10 or later.
