A vulnerability in the session identification management functionality of the web-based management interface for Cisco Meeting Server could allow an unauthenticated, local attacker to hijack a valid user session identifier. The vulnerability exists because the affected application does not assign a new session identifier to a user session when a user authenticates to the application. An attacker could exploit this vulnerability by using a hijacked session identifier to connect to the application through the web-based management interface. A successful exploit could allow the attacker to hijack an authenticated user's browser session. There are no workarounds that address this vulnerability.
