CVE-2021-1256 – Cisco Firepower Threat Defense Software Command File Overwrite Vulnerability
https://notcve.org/view.php?id=CVE-2021-1256
A vulnerability in the CLI of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to overwrite files on the file system of an affected device by using directory traversal techniques. A successful exploit could cause system instability if important system files are overwritten. This vulnerability is due to insufficient validation of user input for the file path in a specific CLI command. An attacker could exploit this vulnerability by logging in to a targeted device and issuing a specific CLI command with crafted user input. A successful exploit could allow the attacker to overwrite arbitrary files on the file system of the affected device. • https://kc.mcafee.com/corporate/index?page=content&id=SB10382 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-file-overwrite-XknRjGdB • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-552: Files or Directories Accessible to External Parties •
CVE-2021-1402 – Cisco Firepower Threat Defense Software SSL Decryption Policy Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1402
A vulnerability in the software-based SSL/TLS message handler of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of SSL/TLS messages when the device performs software-based SSL decryption. An attacker could exploit this vulnerability by sending a crafted SSL/TLS message through an affected device. SSL/TLS messages sent to an affected device do not trigger this vulnerability. A successful exploit could allow the attacker to cause a process to crash. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-ssl-decrypt-dos-DdyLuK6c • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2021-1368 – Cisco FXOS and NX-OS Software Unidirectional Link Detection Denial of Service and Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-1368
A vulnerability in the Unidirectional Link Detection (UDLD) feature of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code with administrative privileges or cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending crafted Cisco UDLD protocol packets to a directly connected, affected device. A successful exploit could allow the attacker to execute arbitrary code with administrative privileges or cause the Cisco UDLD process to crash and restart multiple times, causing the affected device to reload and resulting in a DoS condition. Note: The UDLD feature is disabled by default, and the conditions to exploit this vulnerability are strict. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-udld-rce-xetH6w35 • CWE-787: Out-of-bounds Write •
CVE-2021-1267 – Cisco Firepower Management Center XML Entity Expansion Vulnerability
https://notcve.org/view.php?id=CVE-2021-1267
A vulnerability in the dashboard widget of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper restrictions on XML entities. An attacker could exploit this vulnerability by crafting an XML-based widget on an affected server. A successful exploit could cause increased memory and CPU utilization, which could result in a DoS condition. Una vulnerabilidad en el widget dashboard del software Cisco Firepower Management Center (FMC), podría permitir a un atacante remoto autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmc-xee-DFzARDcs • CWE-776: Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion') •
CVE-2021-1126 – Cisco Firepower Management Center Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2021-1126
A vulnerability in the storage of proxy server credentials of Cisco Firepower Management Center (FMC) could allow an authenticated, local attacker to view credentials for a configured proxy server. The vulnerability is due to clear-text storage and weak permissions of related configuration files. An attacker could exploit this vulnerability by accessing the CLI of the affected software and viewing the contents of the affected files. A successful exploit could allow the attacker to view the credentials that are used to access the proxy server. Una vulnerabilidad en el almacenamiento de las credenciales del servidor proxy de Cisco Firepower Management Center (FMC), podría permitir a un atacante local autenticado visualizar credenciales de un servidor proxy configurado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmc-infodisc-RJdktM6f • CWE-256: Plaintext Storage of a Password CWE-522: Insufficiently Protected Credentials CWE-732: Incorrect Permission Assignment for Critical Resource •
