CVE-2019-12630 – Cisco Security Manager Java Deserialization Vulnerability
https://notcve.org/view.php?id=CVE-2019-12630
A vulnerability in the Java deserialization function used by Cisco Security Manager could allow an unauthenticated, remote attacker to execute arbitrary commands on an affected device. The vulnerability is due to insecure deserialization of user-supplied content by the affected software. An attacker could exploit this vulnerability by sending a malicious serialized Java object to a specific listener on an affected system. A successful exploit could allow the attacker to execute arbitrary commands on the device with the privileges of casuser. Una vulnerabilidad en la función de deserialización de Java utilizada por Cisco Security Manager, podría permitir a un atacante remoto no autenticado ejecutar comandos arbitrarios sobre un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191002-sm-java-deserial • CWE-20: Improper Input Validation CWE-502: Deserialization of Untrusted Data •
CVE-2019-1903 – Cisco Security Manager XML Entity Expansion Vulnerability
https://notcve.org/view.php?id=CVE-2019-1903
A vulnerability in Cisco Security Manager could allow an unauthenticated, remote attacker to access sensitive information or cause a denial of service (DoS) condition. The vulnerability is due to improper restrictions on XML entities. An attacker could exploit this vulnerability by sending malicious requests to a targeted system that contain references within XML entities. An exploit could allow the attacker to retrieve files from the local system, resulting in the disclosure of sensitive information, or cause the application to consume available resources, resulting in a DoS condition. Una vulnerabilidad en Security Manager de Cisco, podría permitir a un atacante remoto no autenticado acceder a información confidencial o causar una condición de denegación de servicio (DoS). • http://www.securityfocus.com/bid/108857 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190619-csm-xml • CWE-611: Improper Restriction of XML External Entity Reference •
CVE-2019-1715 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software Low-Entropy Keys Vulnerability
https://notcve.org/view.php?id=CVE-2019-1715
A vulnerability in the Deterministic Random Bit Generator (DRBG), also known as Pseudorandom Number Generator (PRNG), used in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a cryptographic collision, enabling the attacker to discover the private key of an affected device. The vulnerability is due to insufficient entropy in the DRBG when generating cryptographic keys. An attacker could exploit this vulnerability by generating a large number of cryptographic keys on an affected device and looking for collisions with target devices. A successful exploit could allow the attacker to impersonate an affected target device or to decrypt traffic secured by an affected key that is sent to or from an affected target device. Una vulnerabilidad en el Deterministic Random Bit Generator (DRBG), conocido como Pseudorandom Number Generator (PRNG), utilizado en los programas Adaptive Security Appliance (ASA) y Firepower Threat Defense (FTD) de Cisco, podría permitir que un atacante remoto no identificado genere una colisión criptográfica, que permite al atacante descubrir la clave privada de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-asa-ftd-entropy • CWE-332: Insufficient Entropy in PRNG •
CVE-2018-15427 – Cisco Video Surveillance Manager Appliance Default Password Vulnerability
https://notcve.org/view.php?id=CVE-2018-15427
A vulnerability in Cisco Video Surveillance Manager (VSM) Software running on certain Cisco Connected Safety and Security Unified Computing System (UCS) platforms could allow an unauthenticated, remote attacker to log in to an affected system by using the root account, which has default, static user credentials. The vulnerability is due to the presence of undocumented, default, static user credentials for the root account of the affected software on certain systems. An attacker could exploit this vulnerability by using the account to log in to an affected system. A successful exploit could allow the attacker to log in to the affected system and execute arbitrary commands as the root user. Una vulnerabilidad en Cisco Video Surveillance Manager (VSM) Software ejecutándose en ciertas plataformas Cisco Connected Safety y Security Unified Computing System (UCS) podría permitir que un atacante remoto no autenticado inicie sesión en un sistema afectado mediante el uso de una cuenta root, que tiene credenciales de usuario estáticas por defecto. • http://www.securityfocus.com/bid/105381 http://www.securitytracker.com/id/1041733 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180921-vsm • CWE-798: Use of Hard-coded Credentials •
CVE-2018-5390 – Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service
https://notcve.org/view.php?id=CVE-2018-5390
Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service. El kernel de Linux en versiones 4.9 y siguientes pueden forzarse a realizar llamadas muy caras a tcp_collapse_ofo_queue() y tcp_prune_ofo_queue() para cada paquete entrante, lo que puede conducir a una denegación de servicio. A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port, thus the attacks cannot be performed using spoofed IP addresses. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2018-004.txt http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20181031-02-linux-en http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/07/06/3 http://www.openwall.com/lists/oss-security/2019/07/06/4 http://www.securityfocus.com/bid/104976 http://www.securitytracker.com/id/1041424 http://www.securitytracker.com/id/1041434 https://access.redhat.co • CWE-400: Uncontrolled Resource Consumption •
