Deeper analysis
CVE-2023-38096 is an authentication bypass vulnerability in the MyHandlerInterceptor class of NETGEAR ProSAFE Network Management System. The flaw stems from improper implementation of the authentication mechanism and affects installations that expose the component to the network. It carries a CVSS 3.1 score of 9.8 and is also tracked as ZDI-CAN-19718.
Remote attackers require no authentication or user interaction to exploit the issue. Successful exploitation grants the ability to bypass authentication entirely, after which an attacker can achieve full control over confidentiality, integrity, and availability of the affected system.
NETGEAR has published security advisory PSV-2023-0024 addressing this and related issues in ProSAFE Network Management System; the Zero Day Initiative has also released details under ZDI-23-920. The EPSS score currently stands at 0.7493 with the same recorded peak, indicating sustained exploitation interest since disclosure.
