CVE-2024-20404 Scanner

Cisco Finesse is a web-based platform used for handling and streamlining call agent operations, primarily within contact centers. It provides a customizable interface that integrates various communication systems, aimed at increasing the efficiency of customer service operations. Developed by Cisco, a leading provider of networking hardware and telecommunications equipment, Finesse is widely deployed across industries needing robust call management capabilities. The platform is essential for enhancing real-time communication, facilitating automated responses, and providing analytics and reporting features. Enterprises leverage Cisco Finesse to improve customer engagement and support operations through advanced yet user-friendly interfaces. It seamlessly integrates into existing infrastructure, offering convenient scalability and adaptability in diverse telecommunication environments.

The Server-Side Request Forgery (SSRF) vulnerability in Cisco Finesse occurs when the system does not adequately filter user-supplied data in HTTP requests. This flaw allows an unauthenticated remote attacker to interact with otherwise internal or restricted network resources through crafted requests. The vulnerability could lead to unintended actions by the web application such as information leakage. SSRF vulnerabilities are critical because they can be exploited to bypass network access controls and gain unauthorized information. Effective exploitation involves the crafting and sending of malicious HTTP requests. This vulnerability highlights significant risks regarding the exposure of sensitive information if left unaddressed.

Technical details regarding this SSRF vulnerability reveal inadequate validation checks in HTTP requests made by Cisco Finesse, particularly involving endpoints that interact with user-defined input. Attackers can inject URLs within these requests that lead to unauthorized system interactions, with potentially harmful consequences. Specifically, these requests leverage the HTTP POST method directed at the `/gadgets/metadata` endpoint, utilizing malformed metadata to instigate unwanted actions. The parameter 'gadgets' within these requests is manipulated to introduce external URLs, bypassing typical validation mechanisms. Such a flaw is particularly concerning when dealing with applications handling sensitive communications and user data.

Exploitation of this SSRF vulnerability can lead to serious implications, including unauthorized access to internal devices and services. Attackers may be able to glean sensitive information from applications and network interfaces that should remain private. This unauthorized access might further streamline subsequent attacks or lateral movements within the target's IT infrastructure. Possible exposure includes sensitive data such as user credentials or configuration files, potentially leading to complete data breaches or disruption of services. In severe cases, attackers might manipulate the vulnerability to pivot further into the network, escalating their access and the potential for harm.
