CVE-2011-2054 – Cisco ASA Secondary Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2011-2054
A vulnerability in the Cisco ASA that could allow a remote attacker to successfully authenticate using the Cisco AnyConnect VPN client if the Secondary Authentication type is LDAP and the password is left blank, providing the primary credentials are correct. The vulnerabilities is due to improper input validation of certain parameters passed to the affected software. An attacker must have the correct primary credentials in order to successfully exploit this vulnerability. Una vulnerabilidad en el Cisco ASA , podría permitir a atacantes remotos una autenticación con éxito usando el cliente Cisco AnyConnect VPN si el tipo Secondary Authentication es LDAP y la contraseña se deja en blanco, siempre que las credenciales principales sean correctas. Estas vulnerabilidades son debido a una comprobación de entrada inapropiada de determinados parámetros pasados ?? • https://quickview.cloudapps.cisco.com/quickview/bug/CSCtq58884 • CWE-287: Improper Authentication •

CVE-2019-1649 – Cisco Secure Boot Hardware Tampering Vulnerability
https://notcve.org/view.php?id=CVE-2019-1649
A vulnerability in the logic that handles access control to one of the hardware components in Cisco's proprietary Secure Boot implementation could allow an authenticated, local attacker to write a modified firmware image to the component. This vulnerability affects multiple Cisco products that support hardware-based Secure Boot functionality. The vulnerability is due to an improper check on the area of code that manages on-premise updates to a Field Programmable Gate Array (FPGA) part of the Secure Boot hardware implementation. An attacker with elevated privileges and access to the underlying operating system that is running on the affected device could exploit this vulnerability by writing a modified firmware image to the FPGA. A successful exploit could either cause the device to become unusable (and require a hardware replacement) or allow tampering with the Secure Boot verification process, which under some circumstances may allow the attacker to install and boot a malicious software image. • http://www.securityfocus.com/bid/108350 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190513-secureboot https://www.kb.cert.org/vuls/id/400865 https://www.us-cert.gov/ics/advisories/icsa-20-072-03 • CWE-284: Improper Access Control CWE-667: Improper Locking •
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 •
