The conversion utility for converting CiscoWorks Wireless LAN Solution Engine (WLSE) 4.1.91.0 and earlier to Cisco Wireless Control System (WCS) creates administrator accounts with default usernames and passwords, which allows remote attackers to gain privileges.

Multiple cross-site scripting (XSS) vulnerabilities in (1) PreSearch.html and (2) PreSearch.class in Cisco Secure Access Control Server (ACS), VPN Client, Unified Personal Communicator, MeetingPlace, Unified MeetingPlace, Unified MeetingPlace Express, CallManager, IP Communicator, Unified Video Advantage, Unified Videoconferencing 35xx products, Unified Videoconferencing Manager, WAN Manager, Security Device Manager, Network Analysis Module (NAM), CiscoWorks and related products, Wireless LAN Solution Engine (WLSE), 2006 Wireless LAN Controllers (WLC), and Wireless Control System (WCS) allow remote attackers to inject arbitrary web script or HTML via the text field of the search form.

Cross-site scripting (XSS) vulnerability in the appliance web user interface in Cisco CiscoWorks Wireless LAN Solution Engine (WLSE) and WLSE Express before 2.13 allows remote attackers to inject arbitrary web script or HTML, possibly via the displayMsg parameter to archiveApplyDisplay.jsp, aka bug ID CSCsc01095.

Cisco CiscoWorks Wireless LAN Solution Engine (WLSE) and WLSE Express before 2.13, Hosting Solution Engine (HSE) and User Registration Tool (URT) before 20060419, and all versions of Ethernet Subscriber Solution Engine (ESSE) and CiscoWorks2000 Service Management Solution (SMS) allow local users to gain Linux shell access via shell metacharacters in arguments to the "show" command in the application's command line interface (CLI), aka bug ID CSCsd21502 (WLSE), CSCsd22861 (URT), and CSCsd22859 (HSE). NOTE: other issues might be addressed by the Cisco advisory.

Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old.

Cisco Wireless LAN Solution Engine (WLSE) 2.0 through 2.5 and Hosting Solution Engine (HSE) 1.7 through 1.7.3 have a hardcoded username and password, which allows remote attackers to add new users, modify existing users, and change configuration.
