Authentication Bypass in Cisco IP Phone 7800 and 8800 Series

CVE-2023-20018

Summary

A security vulnerability exists in the web-based management interface of Cisco's IP Phone 7800 and 8800 Series. This flaw is attributed to inadequate validation of user-provided input, allowing an unauthenticated remote attacker to bypass authentication mechanisms on affected devices. By crafting and sending a specific request to the web management interface, the attacker can potentially gain access to sections that are typically secured. This poses a significant risk, emphasizing the need for users to implement proper security measures and updates.
