CVE-2022-20927
https://notcve.org/view.php?id=CVE-2022-20927
A vulnerability in the SSL/TLS client of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper memory management when a device initiates SSL/TLS connections. An attacker could exploit this vulnerability by ensuring that the device will connect to an SSL/TLS server that is using specific encryption parameters. A successful exploit could allow the attacker to cause the affected device to unexpectedly reload, resulting in a DoS condition. Una vulnerabilidad en el cliente SSL/TLS del software Cisco Adaptive Security Appliance (ASA) y el software Cisco Firepower Threat Defense (FTD) podría permitir que un atacante remoto autenticado cause una condición de Denegación de Servicio (DoS) en un dispositivo afectado. Esta vulnerabilidad se debe a una gestión inadecuada de la memoria cuando un dispositivo inicia conexiones SSL/TLS. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ssl-client-dos-cCrQPkA • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2022-20918
https://notcve.org/view.php?id=CVE-2022-20918
A vulnerability in the Simple Network Management Protocol (SNMP) access controls for Cisco FirePOWER Software for Adaptive Security Appliance (ASA) FirePOWER module, Cisco Firepower Management Center (FMC) Software, and Cisco Next-Generation Intrusion Prevention System (NGIPS) Software could allow an unauthenticated, remote attacker to perform an SNMP GET request using a default credential. This vulnerability is due to the presence of a default credential for SNMP version 1 (SNMPv1) and SNMP version 2 (SNMPv2). An attacker could exploit this vulnerability by sending an SNMPv1 or SNMPv2 GET request to an affected device. A successful exploit could allow the attacker to retrieve sensitive information from the device using the default credential. This attack will only be successful if SNMP is configured, and the attacker can only perform SNMP GET requests; write access using SNMP is not allowed. Una vulnerabilidad en Simple Network Management Protocol (SNMP) para el módulo FirePOWER con control de acceso para Cisco FirePOWER Software para Adaptive Security Appliance (ASA), el software Cisco Firepower Management Center (FMC) y el software Cisco Next-Generation Intrusion Prevention System (NGIPS) podría permitir un atacante remoto no autenticado realice una solicitud GET SNMP utilizando una credencial predeterminada. Esta vulnerabilidad se debe a la presencia de una credencial predeterminada para SNMP versión 1 (SNMPv1) y SNMP versión 2 (SNMPv2). • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmcsfr-snmp-access-6gqgtJ4S • CWE-284: Improper Access Control CWE-287: Improper Authentication •
CVE-2019-1982 – Cisco Firepower Threat Defense Software HTTP Filtering Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1982
A vulnerability in the HTTP traffic filtering component of Cisco Firepower Threat Defense Software, Cisco FirePOWER Services Software for ASA, and Cisco Firepower Management Center Software could allow an unauthenticated, remote attacker to bypass filtering protections. The vulnerability is due to improper handling of HTTP requests, including those communicated over a secure HTTPS connection, that contain maliciously crafted headers. An attacker could exploit this vulnerability by sending malicious requests to an affected device. An exploit could allow the attacker to bypass filtering and deliver malicious requests to protected systems, allowing attackers to deliver malicious content that would otherwise be blocked. Una vulnerabilidad en el componente de filtrado de tráfico HTTP del software Cisco Firepower Threat Defense, el software Cisco FirePOWER Services para ASA y el software Cisco Firepower Management Center, podría permitir a un atacante remoto no autenticado omitir las protecciones de filtrado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190816-ftd- • CWE-264: Permissions, Privileges, and Access Controls CWE-276: Incorrect Default Permissions •
CVE-2019-1981 – Cisco Firepower Threat Defense Software NULL Character Obfuscation Detection Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1981
A vulnerability in the normalization functionality of Cisco Firepower Threat Defense Software, Cisco FirePOWER Services Software for ASA, and Cisco Firepower Management Center Software could allow an unauthenticated, remote attacker to bypass filtering protections. The vulnerability is due to insufficient normalization of a text-based payload. An attacker could exploit this vulnerability by sending traffic that contains specifically obfuscated payloads through an affected device. An exploit could allow the attacker to bypass filtering and deliver malicious payloads to protected systems that would otherwise be blocked. Una vulnerabilidad en la funcionalidad de normalización del software Cisco Firepower Threat Defense, el software Cisco FirePOWER Services para ASA y el software Cisco Firepower Management Center, podría permitir a un atacante remoto no autenticado omitir las protecciones de filtrado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190816-ftd-null • CWE-20: Improper Input Validation CWE-264: Permissions, Privileges, and Access Controls •
CVE-2019-1980 – Cisco Firepower Threat Defense Software Nonstandard Protocol Detection Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-1980
A vulnerability in the protocol detection component of Cisco Firepower Threat Defense Software, Cisco FirePOWER Services Software for ASA, and Cisco Firepower Management Center Software could allow an unauthenticated, remote attacker to bypass filtering protections. The vulnerability is due to improper detection of the initial use of a protocol on a nonstandard port. An attacker could exploit this vulnerability by sending traffic on a nonstandard port for the protocol in use through an affected device. An exploit could allow the attacker to bypass filtering and deliver malicious requests to protected systems that would otherwise be blocked. Once the initial protocol flow on the nonstandard port is detected, future flows on the nonstandard port will be successfully detected and handled as configured by the applied policy. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190816-ftd-nspd • CWE-264: Permissions, Privileges, and Access Controls CWE-287: Improper Authentication •
