CVSS: 7.7EPSS: 0%CPEs: 16EXPL: 0CVE-2019-12677 – Cisco Adaptive Security Appliance Software SSL VPN Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-12677
A vulnerability in the Secure Sockets Layer (SSL) VPN feature of Cisco Adaptive Security Appliance (ASA) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition that prevents the creation of new SSL/Transport Layer Security (TLS) connections to an affected device. The vulnerability is due to incorrect handling of Base64-encoded strings. An attacker could exploit this vulnerability by opening many SSL VPN sessions to an affected device. The attacker would need to have valid user credentials on the affected device to exploit this vulnerability. A successful exploit could allow the attacker to overwrite a special system memory location, which will eventually result in memory allocation errors for new SSL/TLS sessions to the device, preventing successful establishment of these sessions. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191002-asa-ssl-vpn-dos • CWE-172: Encoding Error CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 7.4EPSS: 0%CPEs: 17EXPL: 0CVE-2019-12676 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software OSPF LSA Processing Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-12676
A vulnerability in the Open Shortest Path First (OSPF) implementation of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, adjacent attacker to cause a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability exists because the affected software improperly parses certain options in OSPF link-state advertisement (LSA) type 11 packets. An attacker could exploit this vulnerability by sending a crafted LSA type 11 OSPF packet to an affected device. A successful exploit could allow the attacker to cause a reload of the affected device, resulting in a DoS condition for client traffic that is traversing the device. Una vulnerabilidad en la implementación de Open Shortest Path First (OSPF) del Software Cisco Adaptive Security Appliance (ASA) y el Software Cisco Firepower Threat Defense (FTD), podría permitir a un atacante adyacente no autenticado causar una recarga de un dispositivo afectado, resultando en una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191002-asa-ospf-lsa-dos • CWE-20: Improper Input Validation •
CVSS: 8.6EPSS: 0%CPEs: 17EXPL: 0CVE-2019-12673 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software FTP Inspection Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-12673
A vulnerability in the FTP inspection engine of Cisco Adaptive Security (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient validation of FTP data. An attacker could exploit this vulnerability by sending malicious FTP traffic through an affected device. A successful exploit could allow the attacker to cause a DoS condition on the affected device. Una vulnerabilidad en el motor de inspección FTP del Software Cisco Adaptive Security (ASA) y el Software Cisco Firepower Threat Defense (FTD), podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191002-asa-dos • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

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 •

https://notcve.org/view.php?id=CVE-2019-1713
A vulnerability in the web-based management interface of Cisco Adaptive Security Appliance (ASA) Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system. The vulnerability is due to insufficient CSRF protections for the web-based management interface on an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the affected user. If the user has administrative privileges, the attacker could alter the configuration of, extract information from, or reload an affected device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190501-asa-csrf • CWE-352: Cross-Site Request Forgery (CSRF) •
