## Affected

- Cisco Cisco Crosswork Network Change Automation: 3.0.0, 3.0.1, 1.0.0, 2.0.0, 2.0.1, 3.0.2, 2.0.2, 3.0.3, 4.0.0, 4.1.0, 4.5.0, 4.1.1, 5.0.0, 4.5.1, 4.1.2, 5.0.1, 4.5.2, 5.0.2, 4.1.3, 6.0.0, 4.1.4, 6.0.2, 5.0.3

## Description

Multiple vulnerabilities in the web-based management interface of Cisco Crosswork Network Controller could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks against users of the interface of an affected system. These vulnerabilities exist because the web-based management interface does not properly validate user-supplied input. An attacker could exploit these vulnerabilities by inserting malicious data into specific data fields in the interface. 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. To exploit these vulnerabilities, the attacker must have valid administrative credentials. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
