Cross-site scripting (XSS) vulnerability in Cisco IOS Web Server for IOS 12.0(2a) allows remote attackers to inject arbitrary web script or HTML by (1) packets containing HTML that an administrator views via an HTTP interface to the contents of memory buffers, as demonstrated by the URI /level/15/exec/-/buffers/assigned/dump; or (2) sending the router Cisco Discovery Protocol (CDP) packets with HTML payload that an administrator views via the CDP status pages. NOTE: these vectors were originally reported as being associated with the dump and packet options in /level/15/exec/-/show/buffers. • http://secunia.com/advisories/17780 http://secunia.com/advisories/18528 http://securityreason.com/securityalert/227 http://securitytracker.com/id?1015275 http://www.cisco.com/warp/public/707/cisco-sa-20051201-http.shtml http://www.idefense.com/intelligence/vulnerabilities/display.php?id=372 http://www.infohacking.com/INFOHACKING_RESEARCH/Our_Advisories/cisco/index.html http://www.securityfocus.com/archive/1/417916/100/0/threaded http://www.securityfocus.com/bid/15602 http://www.securit •

Cisco IOS 12.2(15) and earlier allows remote attackers to cause a denial of service (refused VTY (virtual terminal) connections), via a crafted TCP connection to the Telnet or reverse Telnet port. Cisco IOS contains an unspecified vulnerability that may block further telnet, reverse telnet, Remote Shell (RSH), Secure Shell (SSH), and in some cases, Hypertext Transport Protocol (HTTP) access to the Cisco device. • http://secunia.com/advisories/12395 http://securitytracker.com/id?1011079 http://www.cisco.com/warp/public/707/cisco-sa-20040827-telnet.shtml http://www.kb.cert.org/vuls/id/384230 http://www.securityfocus.com/bid/11060 https://exchange.xforce.ibmcloud.com/vulnerabilities/17131 •
