Synopsis

The remote device is missing a vendor-supplied security patch

Description

According to its self-reported version, Cisco Webex Meetings is prior to 40.6.0. It is, therefore, affected by a Reflected Cross-Site Scripting (XSS) vulnerability. An unauthenticated, remote attacker can exploit this vulnerability by persuading a user to click a malicious link. A successful exploit allows the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.

Please see the included Cisco BID and Cisco Security Advisory for more information.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
