A vulnerability in the XML application programming interface (API) of Cisco WebEx Meetings Server could allow an unauthenticated, remote attacker to view sensitive information. The vulnerability is due to improper sanitization of return messages. An attacker could exploit this vulnerability by sending crafted GET requests to a vulnerable device. Cisco has confirmed the vulnerability in a security notice and released software updates. To exploit this vulnerability, an attacker may need access to trusted, internal networks behind a firewall to send crafted GET requests to the targeted device. This access requirement may reduce the likelihood of a successful exploit. Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory.
