Threat & Defense at a Glance

What attackers do: exploitation maps to Exploitation for Privilege Escalation (T1068). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-3 Access Enforcement good match

prevent

Enforces approved authorizations including role-based checks to block low-privilege users from accessing the admin backend via shared authentication guards.

AC-6 Least Privilege good match

prevent

Applies least privilege principle to explicitly limit User role access to administrative functions, preventing privilege escalation.

AC-24 Access Control Decisions good match

prevent

Mandates access control decisions based on role attributes, directly countering the absence of role verification in admin login.

Why these techniques?

The access control flaw directly enables an authenticated low-privilege account to reach the admin backend, constituting exploitation for privilege escalation (T1068).

NVD Description

LavaLite CMS 10.1.0 is vulnerable to Incorrect Access Control. An authenticated user with low-level privileges (User role) can directly access the admin backend by logging in through /admin/login. The vulnerability exists because the admin and user authentication guards share the…

same user provider without role-based access control verification.

Deeper analysisAI

LavaLite CMS version 10.1.0 is affected by CVE-2025-70866, an Incorrect Access Control vulnerability published on 2026-02-13. The flaw allows an authenticated user with low-level privileges, specifically the User role, to directly access the admin backend by logging in through the /admin/login endpoint. This occurs because the admin and user authentication guards share the same user provider without role-based access control verification. The vulnerability carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) and maps to CWE-284.

An attacker requires only a valid low-privilege User role account to exploit this over the network with low complexity and no user interaction. By logging into the /admin/login endpoint, the attacker bypasses intended restrictions and gains full access to the admin backend, enabling high-impact actions that compromise confidentiality, integrity, and availability of the CMS, such as modifying sensitive data or administrative settings.
