Description

DNN Vulnerable to Stored Cross-Site Scripting (XSS) in the Prompt module

# Summary

The Prompt module allows execution of commands that can return raw HTML. Malicious input, even if sanitized for display elsewhere, can be executed when processed through certain commands, leading to potential script execution (XSS).

# Description

The application sanitizes most user-submitted data before displaying it in entry forms. However, the Prompt module is capable of running commands whose output is treated as HTML. This creates a vulnerability where a malicious user can craft input containing embedded scripts or harmful markup.

If such malicious content is later processed by a Prompt command and returned as HTML, it bypasses the standard sanitation mechanisms. Simply executing a specific command through the Prompt module could render this untrusted data and cause unintended script execution in the browser specially in the context of a super-user.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. A user must be tricked into taking some action. The scope is changed, meaning a successful attack can affect components beyond the vulnerable one. Rated impact: confidentiality high, integrity high, availability high.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: Required — someone has to click, open or visit something.
  • Scope: Changed — a successful attack reaches components beyond the vulnerable one.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: High — total loss, or loss the attacker controls.
  • Availability impact: High — total loss, or loss the attacker controls.
