Description

A vulnerability in the Tomcat implementation for Cisco Unified Contact Center Express (Unified CCX) could allow an unauthenticated, remote attacker to cause a web cache poisoning attack on an affected device.

This vulnerability is due to improper input validation of HTTP requests. An attacker could exploit this vulnerability by sending crafted HTTP requests to a specific API endpoint on the Unified CCX Finesse Portal. A successful exploit could allow the attacker to cause the internal WebProxy to redirect users to an attacker-controlled host.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity low, availability none.
