CVE-2024-20280 – Cisco UCS Central Software Configuration Backup Static Key Vulnerability
https://notcve.org/view.php?id=CVE-2024-20280
A vulnerability in the backup feature of Cisco UCS Central Software could allow an attacker with access to a backup file to learn sensitive information that is stored in the full state and configuration backup files. This vulnerability is due to a weakness in the encryption method that is used for the backup function. An attacker could exploit this vulnerability by accessing a backup file and leveraging a static key that is used for the backup configuration feature. A successful exploit could allow an attacker with access to a backup file to learn sensitive information that is stored in full state backup files and configuration backup files, such as local user credentials, authentication server passwords, Simple Network Management Protocol (SNMP) community names, and the device SSL server certificate and key. Una vulnerabilidad en la función de copia de seguridad de Cisco UCS Central Software podría permitir que un atacante con acceso a un archivo de copia de seguridad obtenga información confidencial almacenada en los archivos de copia de seguridad de estado completo y de configuración. Esta vulnerabilidad se debe a una debilidad en el método de cifrado que se utiliza para la función de copia de seguridad. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ucsc-bkpsky-TgJ5f73J • CWE-321: Use of Hard-coded Cryptographic Key CWE-798: Use of Hard-coded Credentials •
CVE-2021-34736 – Cisco Integrated Management Controller GUI Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-34736
A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) Software could allow an unauthenticated, remote attacker to cause the web-based management interface to unexpectedly restart. The vulnerability is due to insufficient input validation on the web-based management interface. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to cause the interface to restart, resulting in a denial of service (DoS) condition. Una vulnerabilidad en la interfaz de administración basada en web de Cisco Integrated Management Controller (IMC) Software podría permitir a un atacante remoto no autenticado causar el reinicio inesperado de la interfaz de administración basada en web. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-imc-gui-dos-TZjrFyZh • CWE-20: Improper Input Validation •
CVE-2021-1590 – Cisco NX-OS Software system login block-for Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1590
A vulnerability in the implementation of the system login block-for command for Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a login process to unexpectedly restart, causing a denial of service (DoS) condition. This vulnerability is due to a logic error in the implementation of the system login block-for command when an attack is detected and acted upon. An attacker could exploit this vulnerability by performing a brute-force login attack on an affected device. A successful exploit could allow the attacker to cause a login process to reload, which could result in a delay during authentication to the affected device. Una vulnerabilidad en la implementación del comando system login block-for para el Software Cisco NX-OS, podría permitir a un atacante remoto no autenticado causar que un proceso de inicio de sesión se reinicie inesperadamente, causando una condición de denegación de servicio (DoS). • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-login-blockfor-RwjGVEcu • CWE-787: Out-of-bounds Write •
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-2020-10136 – IP-in-IP protocol allows a remote, unauthenticated attacker to route arbitrary network traffic
https://notcve.org/view.php?id=CVE-2020-10136
IP-in-IP protocol specifies IP Encapsulation within IP standard (RFC 2003, STD 1) that decapsulate and route IP-in-IP traffic is vulnerable to spoofing, access-control bypass and other unexpected behavior due to the lack of validation to verify network packets before decapsulation and routing. Múltiples productos que implementan la IP Encapsulation dentro del estándar IP (RFC 2003, STD 1) desencapsulan y enrutan el tráfico IP-in-IP sin ninguna comprobación, lo que podría permitir a un atacante remoto no autenticado enrutar tráfico arbitrario por medio de una interfaz de red expuesta y conllevar a una falsificación, omisión de control de acceso y otros comportamientos inesperados de la red. • https://datatracker.ietf.org/doc/html/rfc6169 https://kb.cert.org/vuls/id/636397 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-ipip-dos-kCT9X4 https://www.digi.com/resources/security https://www.kb.cert.org/vuls/id/636397 • CWE-290: Authentication Bypass by Spoofing •
