Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-14 Permitted Actions Without Identification or Authentication good match

prevent

Explicitly defines and limits actions permitted without identification or authentication, directly preventing the router from treating crafted URLs like '?x=1.gif' as authenticated.

AC-3 Access Enforcement good match

prevent

Enforces approved access authorizations, blocking unauthorized access to router administrative functions despite the authentication bypass vulnerability.

SI-2 Flaw Remediation good match

preventrecover

Mandates identification, reporting, and correction of flaws such as this CVE through firmware updates to eliminate the authentication bypass.

Why these techniques?

The CVE describes an authentication bypass vulnerability in the Netgear DGN2200 router's web management interface via a URL parameter (?x=1.gif), enabling exploitation of a public-facing application to gain unauthorized administrative access.

NVD Description

A vulnerability in the Netgear DGN2200 router with firmware version v1.0.0.46 and earlier permits unauthorized individuals to bypass the authentication. When adding "?x=1.gif" to the the requested url, it will be recognized as passing the authentication.

Deeper analysisAI

CVE-2024-57046 is an authentication bypass vulnerability (CWE-287) in the Netgear DGN2200 router running firmware version v1.0.0.46 and earlier. The flaw allows unauthorized individuals to circumvent authentication by appending "?x=1.gif" to any requested URL, causing the router to treat the request as authenticated.

Attackers on an adjacent network (AV:A) can exploit this with low complexity (AC:L), no required privileges (PR:N), and no user interaction (UI:N). Successful exploitation provides high-impact access to confidentiality, integrity, and availability (C:H/I:H/A:H), with a CVSS v3.1 base score of 8.8, enabling potential full administrative control of the device.
