Lifecycle Timeline
2Description
Multiple vulnerabilities in the web-based management interface of Cisco Packaged Contact Center Enterprise (Packaged CCE) and Cisco Unified Contact Center Enterprise (Unified CCE) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. These vulnerabilities exist because the web-based management interface does not properly validate user-supplied input. An attacker could exploit these vulnerabilities by injecting malicious code into specific pages of 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.
Analysis
Stored XSS vulnerabilities in Cisco Packaged CCE and Unified CCE web management interfaces allow authenticated attackers to inject malicious scripts by exploiting insufficient input validation. Successful exploitation enables arbitrary script execution within the management interface context or theft of sensitive browser-based information from authorized users. …
