Cisco WebEx Multiple Cross-Site Scripting Vulnerabilities

Multiple vulnerabilities in Cisco WebEx Business Suite could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack.

The vulnerabilities are due to insufficient validation of user-supplied input. An attacker could exploit these vulnerabilities by convincing a user to click a crafted URL.

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.

Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
