CVSS: 7.5EPSS: 0%CPEs: 13EXPL: 0CVE-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 •
CVSS: 8.6EPSS: 0%CPEs: 21EXPL: 0CVE-2019-1714 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software VPN SAML Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1714
A vulnerability in the implementation of Security Assertion Markup Language (SAML) 2.0 Single Sign-On (SSO) for Clientless SSL VPN (WebVPN) and AnyConnect Remote Access VPN in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to successfully establish a VPN session to an affected device. The vulnerability is due to improper credential management when using NT LAN Manager (NTLM) or basic authentication. An attacker could exploit this vulnerability by opening a VPN session to an affected device after another VPN user has successfully authenticated to the affected device via SAML SSO. A successful exploit could allow the attacker to connect to secured networks behind the affected device. Una vulnerabilidad en la implementación del Security Assertion Markup Language (SAML) versión 2.0 Single Sign-On (SSO) para VPN SSL sin clientes (WebVPN) y AnyConnect Remote Access VPN en Cisco Adaptive Security Appliance (ASA) Programa y Cisco Firepower Threat Defense (FTD) El programa podría permitir a un atacante remoto no autenticado establecer con éxito una sesión VPN en un dispositivo afectado. • http://www.securityfocus.com/bid/108185 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-asaftd-saml-vpn • CWE-255: Credentials Management Errors •
CVSS: 8.6EPSS: 0%CPEs: 13EXPL: 0CVE-2019-1708 – Cisco Adaptive Security Appliance Software and Cisco Firepower Threat Defense Software MOBIKE Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1708
A vulnerability in the Internet Key Exchange Version 2 Mobility and Multihoming Protocol (MOBIKE) feature for the Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a memory leak or a reload of an affected device that leads to a denial of service (DoS) condition. The vulnerability is due to the incorrect processing of certain MOBIKE packets. An attacker could exploit this vulnerability by sending crafted MOBIKE packets to an affected device to be processed. A successful exploit could cause an affected device to continuously consume memory and eventually reload, resulting in a DoS condition. The MOBIKE feature is supported only for IPv4 addresses. • http://www.securityfocus.com/bid/108166 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-asa-ftd-ike-dos • CWE-401: Missing Release of Memory after Effective Lifetime CWE-404: Improper Resource Shutdown or Release •
CVSS: 4.8EPSS: 0%CPEs: 19EXPL: 0CVE-2019-1701 – Cisco Adaptive Security Appliance and Firepower Threat Defense Software WebVPN Cross-Site Scripting Vulnerabilities
https://notcve.org/view.php?id=CVE-2019-1701
Multiple vulnerabilities in the WebVPN service of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the WebVPN portal of an affected device. The vulnerabilities exist because the software insufficiently validates user-supplied input on an affected device. An attacker could exploit these vulnerabilities by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive browser-based information. An attacker would need administrator privileges on the device to exploit these vulnerabilities. • http://www.securityfocus.com/bid/108152 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-asa-ftd-xss • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 8.6EPSS: 0%CPEs: 5EXPL: 0CVE-2019-1703 – Cisco Firepower Threat Defense Software Packet Processing Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-1703
A vulnerability in the internal packet-processing functionality of Cisco Firepower Threat Defense (FTD) Software for the Cisco Firepower 2100 Series could allow an unauthenticated, remote attacker to cause an affected device to stop processing traffic, resulting in a denial of service (DoS) condition. The vulnerability is due to a logic error, which may prevent ingress buffers from being replenished under specific traffic conditions. An attacker could exploit this vulnerability by sending a series of crafted packets to an affected device. A successful exploit could allow the attacker to consume all input buffers, which are shared between all interfaces, leading to a queue wedge condition in all active interfaces. This situation would cause an affected device to stop processing any incoming traffic and result in a DoS condition until the device is reloaded manually. • http://www.securityfocus.com/bid/108170 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-frpwr-dos • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
