Fix not verifiedAn authenticated OS command injection vulnerability exists in Netgear routers (tested on the DGN2200B model) firmware versions 1.0.0.36 and prior via the pppoe.cgi endpoint. A remote attacker with valid credentials can execute arbitrary commands via crafted input to the pppoe_username parameter. This flaw allows full compromise of the device and may persist across reboots unless configuration is restored.

Untrusted input is incorporated into an operating-system command without safe parameter handling.
An attacker operating through a network path may attempt exploitation with elevated privileges. If successful, the issue may execute code or commands in the affected security context.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.
CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'). The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
