Memory leak in the virtual private dial-up network (VPDN) component in Cisco IOS before 12.3 allows remote attackers to cause a denial of service (memory consumption) via a series of PPTP sessions, related to "dead memory" that remains allocated after process termination, aka bug ID CSCsj58566. Fugas de memoria en la componente de red privada virtual dial-up (VPDN) en Cisco IOS versiones anteriores a 12.3 permite a atacantes remotos provocar una denegación de servicio (consumo de memoria) a través de una serie de sesiones PPTP, en relación a "dead memory" que permanece asignado después de la finalización del proceso, también conocido como bug ID CSCsj58566. • http://secunia.com/advisories/29507 http://securitytracker.com/id?1019714 http://www.cisco.com/en/US/products/products_security_advisory09186a0080969862.shtml http://www.securityfocus.com/bid/28460 http://www.us-cert.gov/cas/techalerts/TA08-087B.html http://www.vupen.com/english/advisories/2008/1006/references https://exchange.xforce.ibmcloud.com/vulnerabilities/41483 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A5287 • CWE-399: Resource Management Errors •

Cisco IOS 12.2 through 12.4 before 20060920, as used by Cisco IAD2430, IAD2431, and IAD2432 Integrated Access Devices, the VG224 Analog Phone Gateway, and the MWR 1900 and 1941 Mobile Wireless Edge Routers, is incorrectly identified as supporting DOCSIS, which allows remote attackers to gain read-write access via a hard-coded cable-docsis community string and read or modify arbitrary SNMP variables. Cisco IOS 12.2 hasta 12.4 anteriores al 20/09/2006, usados por Cisco IAD2430, IAD2431, y IAD2432 Integrated Access Devices, el VG224 Analog Phone Gateway, y el MWR 1900 y 1941 Mobile Wireless Edge Routers, está identificado de forma incorrecta como soporte DOCSIS, lo que permiet a un atacante remoto conseguir acceso lectura-escritura a través de una secuencia de hard-coded cable-docsis y leer o modificar variables SNMP de su elección. • http://secunia.com/advisories/21974 http://securitytracker.com/id?1016899 http://www.cisco.com/warp/public/707/cisco-sa-20060920-docsis.shtml http://www.kb.cert.org/vuls/id/123140 http://www.osvdb.org/29034 http://www.securityfocus.com/bid/20125 http://www.vupen.com/english/advisories/2006/3722 https://exchange.xforce.ibmcloud.com/vulnerabilities/29054 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A5665 •

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 •
