A vulnerability in the web framework of Cisco Transport Gateway for Smart Call Home (TG-SCH) could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against the user of the web interface of the affected system.
The vulnerability is due to insufficient input validation of some parameters passed to the web server. An attacker could exploit this vulnerability by convincing the user to access a malicious link or by intercepting the user request and injecting the malicious input.
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 to persuade the user to follow the provided link.
