CVE-2023-20250 : What You Need to Know

This CVE-2023-20250 vulnerability involves a flaw in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers. The vulnerability could potentially allow an authenticated remote attacker to execute arbitrary code on an affected device.

Understanding CVE-2023-20250

This section delves into the details of the CVE-2023-20250 vulnerability, outlining its impact, technical aspects, affected systems and versions, as well as mitigation strategies.

What is CVE-2023-20250?

The CVE-2023-20250 vulnerability arises due to inadequate validation of requests sent to the web-based management interface. An attacker with valid Administrator credentials can exploit this flaw by sending a specially crafted request to the interface. Successful exploitation could lead to the execution of arbitrary code with root privileges on the compromised device.

The Impact of CVE-2023-20250

Given the nature of this vulnerability, an attacker could potentially gain unauthorized access to and control over the affected device. This unauthorized access could result in a breach of confidential data, compromise of system integrity, and disruption of services, posing a significant security risk.

Technical Details of CVE-2023-20250

The technical details of CVE-2023-20250 shed light on the vulnerability description, affected systems and versions, as well as the exploitation mechanism.

Vulnerability Description

The vulnerability stems from the lack of proper validation of requests to the web-based management interface of the Cisco Small Business RV Series Router Firmware. This oversight allows attackers to execute arbitrary code with root privileges.
