CVE-2019-1967 – Cisco NX-OS Software Network Time Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1967
A vulnerability in the Network Time Protocol (NTP) feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to excessive use of system resources when the affected device is logging a drop action for received MODE_PRIVATE (Mode 7) NTP packets. An attacker could exploit this vulnerability by flooding the device with a steady stream of Mode 7 NTP packets. A successful exploit could allow the attacker to cause high CPU and memory usage on the affected device, which could cause internal system processes to restart or cause the affected device to unexpectedly reload. Note: The NTP feature is enabled by default. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190828-nxos-ntp-dos • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •

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 •
