CVE-2008-0960 – SNMPv3 - HMAC Validation error Remote Authentication Bypass
https://notcve.org/view.php?id=CVE-2008-0960
SNMPv3 HMAC verification in (1) Net-SNMP 5.2.x before 5.2.4.1, 5.3.x before 5.3.2.1, and 5.4.x before 5.4.1.1; (2) UCD-SNMP; (3) eCos; (4) Juniper Session and Resource Control (SRC) C-series 1.0.0 through 2.0.0; (5) NetApp (aka Network Appliance) Data ONTAP 7.3RC1 and 7.3RC2; (6) SNMP Research before 16.2; (7) multiple Cisco IOS, CatOS, ACE, and Nexus products; (8) Ingate Firewall 3.1.0 and later and SIParator 3.1.0 and later; (9) HP OpenView SNMP Emanate Master Agent 15.x; and possibly other products relies on the client to specify the HMAC length, which makes it easier for remote attackers to bypass SNMP authentication via a length value of 1, which only checks the first byte. Una comprobación SNMPv3 HMAC en (1) Net-SNMP versión 5.2.x anterior a 5.2.4.1, versión 5.3.x anterior a 5.3.2.1 y versión 5.4.x anterior a 5.4.1.1; (2) UCD-SNMP; (3) eCos; (4) C-series versión 1.0.0 hasta 2.0.0 de Juniper Session and Resource Control (SRC); (5) Data de NetApp (también se conoce como Network Appliance) ONTAP versiones 7.3RC1 y 7.3RC2; (6) SNMP Research versión anterior a 16.2; (7) múltiples productos Cisco IOS, CatOS, ACE y Nexus; (8) Ingate Firewall versión 3.1.0 y posterior y SIParator versión 3.1.0 y posterior; (9) HP OpenView SNMP Emanate Master Agent versión 15.x; y posiblemente otros productos dependen del cliente para especificar la longitud del HMAC, lo que facilita que los atacantes remotos omitan la autenticación SNMP por medio de un valor de longitud de 1, que solo comprueba el primer byte. • https://www.exploit-db.com/exploits/5790 http://lists.apple.com/archives/security-announce/2008//Jun/msg00002.html http://lists.ingate.com/pipermail/productinfo/2008/000021.html http://lists.opensuse.org/opensuse-security-announce/2008-08/msg00000.html http://marc.info/?l=bugtraq&m=127730470825399&w=2 http://rhn.redhat.com/errata/RHSA-2008-0528.html http://secunia.com/advisories/30574 http://secunia.com/advisories/30596 http://secunia.com/advisories/30612 http://secunia.c • CWE-287: Improper Authentication •
CVE-2005-4258
https://notcve.org/view.php?id=CVE-2005-4258
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. (tcc LanD). NOTA: La proveniencia de esta cuestión es desconocida; los detalles son obtenidos exclusivamente de BID. • http://www.securityfocus.com/bid/15864 https://exchange.xforce.ibmcloud.com/vulnerabilities/44543 •

https://notcve.org/view.php?id=CVE-2004-0551
Cisco CatOS 5.x before 5.5(20) through 8.x before 8.2(2) and 8.3(2)GLX, as used in Catalyst switches, allows remote attackers to cause a denial of service (system crash and reload) by sending invalid packets instead of the final ACK portion of the three-way handshake to the (1) Telnet, (2) HTTP, or (3) SSH services, aka "TCP-ACK DoS attack." Cisco CatOS anteriores a 5.5(20) a 8.x anteriores a 8.2(2) y 8.3(3) GLX, usados en conmutadores Catalyst, permiten a atacantes remotos causar una denegación de servicio (caída del sistema y reinicio) enviando paquétes no válidos en lugar de la porción final ACK del apretón de manos (handshake) en tres pasos a los servicios (1) Telnet, (2) HTTP, o (3) SSH. También conocida como aka "ataque de DoS TCP-ACK ". • http://www.cisco.com/warp/public/707/cisco-sa-20040609-catos.shtml http://www.kb.cert.org/vuls/id/245190 https://exchange.xforce.ibmcloud.com/vulnerabilities/16370 •
