CWE-79
Summary
A vulnerability in the HTTP web-based management interface of Cisco Meeting
Server Software, formerly Acano Conferencing Server, could allow an
unauthenticated, remote attacker to conduct a persistent cross-site scripting
(XSS) attack against a user of the web interface of an affected system.
The vulnerability is due to improper input validation of certain parameters
that are passed to an affected device via an HTTP request. An attacker could
exploit this vulnerability by persuading a user to follow a malicious link. A
successful exploit could allow the attacker to execute arbitrary script code
in the context of the affected management interface or allow the attacker to
access sensitive browser-based information.
Additional information about XSS attacks and potential mitigations can be
found in the following resources:
OWASP Attack Reference: Cross-site Scripting (XSS)
