Version Summary:Cisco Prime Infrastructure contains a vulnerability that could allow an unauthenticated, remote attacker to conduct cross-site scripting attacks. Updates are not available.
 
 
Description
A vulnerability in the wireless configuration module of Cisco Prime Infrastructure could allow an unauthenticated, remote attacker to insert scripts into the listing of rogue access points.

The vulnerability is due to a failure to properly sanitize SSIDs before inserting them into the XML windowing table used to display the list of rogue access points. An attacker could exploit this vulnerability by using a script as the SSID of a rogue access point. A successful exploit could allow the attacker to to execute scripts in the browser of a user viewing the malicious SSID.

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 Prime Infrastructure version 1.2 is affected. Later releases of Cisco Prime Infrastructure may also be affected.
 
IntelliShield Analysis
To exploit this vulnerability, the attacker would likely need access to a trusted, internal network in order to use a malicious script as the SSID of a rogue access point or have the knowledge of whether rogue access points exist in the network.

Customers are advised to review the bug reports in the "Vendor Announcements" section for a current list of affected versions.
 
Vendor Announcements
Cisco has released a security notice for bug ID CSCuf04356 at the following link: CVE-2013-1247
 
Impact
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary script code in the user's browser session. If successful, the attacker could access sensitive information, such as session cookies.
