Description

DNN Vulnerable to Stored XSS Using Backend Admin Credentials

# Summary

Users that can edit modules could set a title that includes scripts.

# Description

Some users (administrators and content editors) can set html in module titles and that could include javascript which could be used for XSS based attacks. With the addition of more roles being able to set module titles, this is not strictly limited to administrators. However since HTML in module titles could be a valid use case, we have added a setting for this functionality in the Security module in the Persona Bar.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs administrative privileges on the target. A user must be tricked into taking some action. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity low, availability none.

CVSS metrics in full

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

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: High — administrative rights are needed first.
  • User interaction: Required — someone has to click, open or visit something.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: None.
  • Integrity impact: Low — limited, and the attacker does not choose what is affected.
  • Availability impact: None.
