An Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability, a stored XSS (or persistent), in the Control Center Controller web pages of Juniper Networks Paragon Active Assurance (Formerly Netrounds) allows a high-privilege attacker with 'WRITE' permissions to store one or more malicious scripts that will infect any other authorized user's account when they accidentally trigger the malicious script(s) while managing the device. Triggering these attacks enables the attacker to execute commands with the permissions up to that of the superuser account.

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
