Cisco VPN 3000 series concentrators before 2.5.2(F) allow remote attackers to cause a denial of service via a flood of invalid login requests to (1) the SSL service, or (2) the telnet service, which do not properly disconnect the user after several failed login attempts.

ws_mail.cgi in WebStore 400/400CS 4.14 allows remote authenticated WebStore administrators to execute arbitrary code via shell metacharacters in the kill parameter.

WSSecurity.pl in WebStore allows remote attackers to bypass authentication by providing the program with a filename that exists, which is made easier by (1) inserting a null character or (2) .. (dot dot).

Cisco Virtual Central Office 4000 (VCO/4K) usa cifrado débil para almacenar nombres de usuario y contraseñas en la MIB SNMP, lo que permite a un atacante que conoce el nombre de la comunidad descifrar la contraseña y obtener privilegios.
