CWE-293
Using Referer Field for Authentication
The referer field in HTTP requests can be easily modified and, as such, is not a valid means of message integrity checking.
CVE-2023-20025 (GCVE-0-2023-20025)
Vulnerability from cvelistv5 – Published: 2023-01-19 01:33 – Updated: 2025-03-12 16:18
VLAI?
Summary
A vulnerability in the web-based management interface of Cisco Small Business RV016, RV042, RV042G, and RV082 Routers could allow an unauthenticated, remote attacker to bypass authentication on an affected device.
This vulnerability is due to improper validation of user input within incoming HTTP packets. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web-based management interface. A successful exploit could allow the attacker to bypass authentication and gain root access on the underlying operating system.

Mitigation
Phase: Architecture and Design
Description:
- In order to usefully check if a given action is authorized, some means of strong authentication and method protection must be used. Use other means of authorization that cannot be simply spoofed. Possibilities include a username/password or certificate.
