A vulnerability in the portal page of Cisco Prime Central for Hosted Collaboration Solution could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web interface of the affected system. The vulnerability is due to a failure to properly sanitize user-supplied input. An attacker could exploit this vulnerability by convincing the user to access a malicious link. Cisco has confirmed the vulnerability in a security notice; however, software updates are not available. To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions in an attempt to persuade a user to follow the malicious link. Customers are advised to review the bug report in the Vendor Announcements section for a current list of affected versions.
