CVE-2019-12695 – Cisco Adaptive Security Appliance and Firepower Threat Defense Software WebVPN Cross-Site Scripting Vulnerability
https://notcve.org/view.php?id=CVE-2019-12695
A vulnerability in the Clientless SSL VPN (WebVPN) portal of Cisco Adaptive Security Appliance (ASA) and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability 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 interface or allow the attacker to access sensitive browser-based information. Una vulnerabilidad en el portal Clientless SSL VPN (WebVPN) de Cisco Adaptive Security Appliance (ASA) y el Software Cisco Firepower Threat Defense (FTD), podría permitir a un atacante remoto no autenticado realizar un ataque de tipo cross-site scripting (XSS) contra un usuario de la interfaz de administración basada en web de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191002-asa-xss • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVE-2019-12693 – Cisco Adaptive Security Appliance Software Secure Copy Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-12693
A vulnerability in the Secure Copy (SCP) feature of Cisco Adaptive Security Appliance (ASA) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to the use of an incorrect data type for a length variable. An attacker could exploit this vulnerability by initiating the transfer of a large file to an affected device via SCP. To exploit this vulnerability, the attacker would need to have valid privilege level 15 credentials on the affected device. A successful exploit could allow the attacker to cause the length variable to roll over, which could cause the affected device to crash. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20191002-asa-scp-dos • CWE-190: Integer Overflow or Wraparound CWE-704: Incorrect Type Conversion or Cast •
CVE-2019-12678 – Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software SIP Inspection Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-12678
A vulnerability in the Session Initiation Protocol (SIP) inspection module of Cisco Adaptive Security Appliance (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 improper parsing of SIP messages. An attacker could exploit this vulnerability by sending a malicious SIP packet through an affected device. A successful exploit could allow the attacker to trigger an integer underflow, causing the software to try to read unmapped memory and resulting in a crash. Una vulnerabilidad en el módulo de inspección del Session Initiation Protocol (SIP) del Software Cisco Adaptive Security Appliance (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-ftd-sip-dos • CWE-191: Integer Underflow (Wrap or Wraparound) •
CVE-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 •
CVE-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 •
