The vulnerability is due to insufficient input validation of a parameter. An attacker could exploit this vulnerability by convincing a user to access a malicious link. Cisco has confirmed the vulnerability in a security notice and released software updates. To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link.
