Description

The NEX-Forms – Ultimate Form Builder – Contact forms and much more plugin for WordPress is vulnerable to Limited Code Execution in all versions up to, and including, 8.9.1 via the get_table_records function. This is due to the unsanitized use of user-supplied input in call_user_func(). This makes it possible for authenticated attackers, with Custom-level access, to execute arbitrary PHP functions that meet specific constraints (static methods or global functions accepting a single array parameter).

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. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity low, availability low.

CVSS metrics in full

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

  • 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: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: Low — limited, and the attacker does not choose what is affected.
  • Integrity impact: Low — limited, and the attacker does not choose what is affected.
  • Availability impact: Low — limited, and the attacker does not choose what is affected.
