Description

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') - CVE-2014-3289 Cisco AsyncOS, the underlying OS for the Cisco Email Security Appliance, Web Security Appliance, and Content Security Management Appliance, contains a reflected cross-site scripting vulnerability in the reports overview page of the management interface. An attacker is able to load arbitrary script in the context of the user's browser through thedate_range parameter. Affected Products: Cisco Email Security Appliance 8.0 and earlier Cisco Web Security Appliance 8.0 and earlier Content Security Management Appliance 8.3 and earlier

A remote unauthenticated attacker may be able to execute arbitrary script in the context of the end-user's browser session.

Solution

Apply an Update Cisco has released a patch to address this vulnerability. If you are unable to upgrade, please consider the following workaround.

Restrict Access As a general good security practice, only allow connections from trusted hosts and networks. Note that restricting access does not prevent XSS or CSRF attacks since the attack comes as an HTTP request from a legitimate user's host. Restricting access would prevent an attacker from accessing the web interface using stolen credentials from a blocked network location.
