CVE-2019-1941: Cisco Identity Services Engine

Medium severity, CVSS 6.1. EPSS: 1.3% chance of exploitation in the next 30 days.

A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by persuading a user to click a malicious link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information. At the time of publication, this vulnerability affected Cisco ISE running software releases prior to 2.4.0 Patch 9 and 2.6.0.

Affected products

• Cisco Identity Services Engine: before 2.4.0 (fixed in 2.4.0); version 2.4(0.902) only; version 2.4.0 only; version 2.5(0.225) only
