Cisco Security Advisory-
There are two vulnerabilities that exist in the CiscoWorks Wireless LAN Solution Engine (WLSE). The first is a cross site scripting (XSS) vulnerability that may allow an attacker to gain administrative privileges on the system. The second is a local privilege escalation vulnerability that can be used by an attacker who already has authenticated access to the command line interface to obtain access to the underlying operating system.
Cisco has made free software available to address this vulnerability for affected customers.

This section provides details on affected products.
Vulnerable Products
A CiscoWorks Wireless LAN Solution Engine (WLSE) or WLSE Express running any version of software prior to 2.13 are vulnerable to both of these vulnerabilities.
Several other Cisco products are affected only by the local privilege escalation vulnerability, including Cisco Hosting Solution Engine (HSE), User Registration Tool (URT), Cisco Ethernet Subscriber Solution Engine (ESSE) and CiscoWorks2000 Service Management Solution. A separate Cisco Security Response has been published regarding the impact and the fixes on these products and can be found at https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityResponse/cisco-sr-20060419-priv
Products Confirmed Not Vulnerable
No other Cisco products are affected by both of these vulnerabilities.

CiscoWorks WLSE is a centralized, systems-level application for managing and controlling an entire autonomous Cisco WLAN infrastructure.
Two vulnerabilities exist in the WLSE appliance that may allow an attacker to gain complete control of the device or to obtain access to the underlying operating system.
These issues are documented by the following Cisco bug IDs:
-
CSCsc01095
(registered
customers only) - Cross site scripting vulnerability in WLSE appliance web
interface
This fix addresses the cross site scripting (XSS) vulnerability in the WLSE appliance web user interface. By exploiting this vulnerability, an attacker may obtain the session cookie information and further use this information to gain administrative privileges on the system.
-
CSCsd21502
(registered
customers only) - Privilege escalation to Linux shell
This fix addresses the local privilege escalation from the command line interface of the WLSE appliance. By exploiting this vulnerability an attacker who already has authenticated access to the command line interface may inject a command to obtain a shell account on the underlying operating system.

When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution.
In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center ("TAC") or your contracted maintenance provider for assistance.
These vulnerabilities are fixed in the 2.13 version of WLSE software. Fixed software can be downloaded from the following URL:
