CVE-2018-0455 – Cisco Firepower System Software Detection Engine Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-0455
A vulnerability in the Server Message Block Version 2 (SMBv2) and Version 3 (SMBv3) protocol implementation for the Cisco Firepower System Software could allow an unauthenticated, remote attacker to cause the device to run low on system memory, possibly preventing the device from forwarding traffic. It is also possible that a manual reload of the device may be required to clear the condition. The vulnerability is due to incorrect SMB header validation. An attacker could exploit this vulnerability by sending a custom SMB file transfer through the targeted device. A successful exploit could cause the device to consume an excessive amount of system memory and prevent the SNORT process from forwarding network traffic. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-fp-smb-snort • CWE-19: Data Processing Errors •
CVE-2018-15390 – Cisco Firepower Threat Defense Software FTP Inspection Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-15390
A vulnerability in the FTP inspection engine of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability exists because the affected software fails to release spinlocks when a device is running low on system memory, if the software is configured to apply FTP inspection and an access control rule to transit traffic, and the access control rule is associated with an FTP file policy. An attacker could exploit this vulnerability by sending a high rate of transit traffic through an affected device to cause a low-memory condition on the device. A successful exploit could allow the attacker to cause a software panic on the affected device, which could cause the device to reload and result in a temporary DoS condition. Una vulnerabilidad en el motor de inspección FTP de Cisco Firepower Threat Defense (FTD) Software podría permitir que un atacante remoto sin autenticar haga que el dispositivo afectado se reinicie, provocando una denegación de servicio (DoS) en consecuencia. • http://www.securityfocus.com/bid/105519 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-ftd-inspect-dos • CWE-399: Resource Management Errors CWE-667: Improper Locking •
CVE-2018-15383 – Cisco Adaptive Security Appliance Direct Memory Access Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-15383
A vulnerability in the cryptographic hardware accelerator driver of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a temporary denial of service (DoS) condition. The vulnerability exists because the affected devices have a limited amount of Direct Memory Access (DMA) memory and the affected software improperly handles resources in low-memory conditions. An attacker could exploit this vulnerability by sending a sustained, high rate of malicious traffic to an affected device to exhaust memory on the device. A successful exploit could allow the attacker to exhaust DMA memory on the affected device, which could cause the device to reload and result in a temporary DoS condition. Una vulnerabilidad en el controlador del acelerador de hardware criptográfico de Cisco Adaptive Security Appliance (ASA) Software y Cisco Firepower Threat Defense (FTD) Software podría permitir que un atacante remoto no autenticado provoque que un dispositivo afectado se recargue, lo que resulta en una denegación de servicio (DoS) temporal. • http://www.securitytracker.com/id/1041787 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-asa-dma-dos • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-2018-15397 – Cisco Adaptive Security Appliance IPsec VPN Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2018-15397
A vulnerability in the implementation of Traffic Flow Confidentiality (TFC) over IPsec functionality in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to an error that may occur if the affected software renegotiates the encryption key for an IPsec tunnel when certain TFC traffic is in flight. An attacker could exploit this vulnerability by sending a malicious stream of TFC traffic through an established IPsec tunnel on an affected device. A successful exploit could allow the attacker to cause a daemon process on the affected device to crash, which could cause the device to crash and result in a DoS condition. Una vulnerabilidad en la implementación de Traffic Flow Confidentiality (TFC) en la funcionalidad IPsec en Cisco Adaptive Security Appliance (ASA) Software y Cisco Firepower Threat Defense (FTD) Software podría permitir que un atacante remoto no autenticado provoque que un dispositivo afectado se reinicie inesperadamente, lo que resulta en una denegación de servicio (DoS). • http://www.securitytracker.com/id/1041786 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-asa-ipsec-dos • CWE-320: Key Management Errors •
CVE-2018-0453 – Cisco Firepower Management Center and Firepower System Software Sourcefire Tunnel Control Channel Command Execution Vulnerability
https://notcve.org/view.php?id=CVE-2018-0453
A vulnerability in the Sourcefire tunnel control channel protocol in Cisco Firepower System Software running on Cisco Firepower Threat Defense (FTD) sensors could allow an authenticated, local attacker to execute specific CLI commands with root privileges on the Cisco Firepower Management Center (FMC), or through Cisco FMC on other Firepower sensors and devices that are controlled by the same Cisco FMC. To send the commands, the attacker must have root privileges for at least one affected sensor or the Cisco FMC. The vulnerability exists because the affected software performs insufficient checks for certain CLI commands, if the commands are executed via a Sourcefire tunnel connection. An attacker could exploit this vulnerability by authenticating with root privileges to a Firepower sensor or Cisco FMC, and then sending specific CLI commands to the Cisco FMC or through the Cisco FMC to another Firepower sensor via the Sourcefire tunnel connection. A successful exploit could allow the attacker to modify device configurations or delete files on the device that is running Cisco FMC Software or on any Firepower device that is managed by Cisco FMC. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181003-fp-cmd-injection • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-264: Permissions, Privileges, and Access Controls •
