Version Summary:Cisco Wireless LAN Controller contains a vulnerability that could allow an unauthenticated, remote attacker to conduct cross-frame scripting attacks. Updates are not available.
 
 
Description
A vulnerability in the web interface of the Cisco Wireless LAN Controller (WLC) could allow an unauthenticated, remote attacker to execute a cross-frame scripting (XFS) attack.

The vulnerability is due to insufficient HTML iframe protection. An attacker could exploit this vulnerability by directing a user to an attacker-controlled web page that contains a malicious HTML iframe. An exploit could allow the attacker to conduct clickjacking or other client-side browser attacks.

Cisco has confirmed the vulnerability in a security notice; however, software updates are not available.
 
Warning Indicators
At the time this alert was first published, Cisco WLC version 7.4(.110) and prior were vulnerable. Later releases of Cisco WLC may also be vulnerable.
 
IntelliShield Analysis
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious site and use misleading language or instructions to persuade the user to follow the provided link.

Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
 
Vendor Announcements
Cisco has released a security notice at the following link: CVE-2013-6698

Customers are advised to consult Cisco bug ID CSCuf77821 for the most complete list of affected product versions.
 
Impact
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary script code in the user's browser session under the context of the affected site. An exploit could allow the attacker to conduct other client-side browser attacks.
 
Technical Information
