CVE-2018-0340

MEDIUM 5.4EPSS 1.25%

Does this matter?

Lower severity and a low EPSS score (1.25%). Track it; it rarely justifies an emergency change on its own.

Description

A vulnerability in the web framework of the Cisco Unified Communications Manager (Unified CM) software could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against the user of the web interface of the affected system. The vulnerability is due to insufficient input validation of certain parameters passed to the web server. An attacker could exploit this vulnerability by convincing the user to access a malicious link or by intercepting the user request and injecting certain malicious code. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected site or allow the attacker to access sensitive browser-based information. Cisco Bug IDs: CSCvj00512.
