Unspecified Cisco Catalyst Switches allow remote attackers to cause a denial of service (device crash) via an IP packet with the same source and destination IPs and ports, and with the SYN flag set (aka LanD). NOTE: the provenance of this issue is unknown; the details are obtained solely from the BID. Conmutadores Cisco Catalyst no especificados permiten a atacantes remotos causar una denegación de servicio (caída de dispositivo) mediante un paquete IP con IPs y puertos de origen y destino iguales y con la bandera SYN.

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 •

Secure Shell (SSH) 2 in Cisco IOS 12.0 through 12.3 allows remote attackers to cause a denial of service (device reload) (1) via a username that contains a domain name when using a TACACS+ server to authenticate, (2) when a new SSH session is in the login phase and a currently logged in user issues a send command, or (3) when IOS is logging messages and an SSH session is terminated while the server is sending data. • http://secunia.com/advisories/14854 http://www.cisco.com/warp/public/707/cisco-sa-20050406-ssh.shtml http://www.securityfocus.com/bid/13043 http://www.securitytracker.com/alerts/2005/Apr/1013655.html https://exchange.xforce.ibmcloud.com/vulnerabilities/19987 https://exchange.xforce.ibmcloud.com/vulnerabilities/19989 https://exchange.xforce.ibmcloud.com/vulnerabilities/19990 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A5455 • CWE-287: Improper Authentication •

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 •
