CVSS: 6.7EPSS: 0%CPEs: 54EXPL: 0CVE-2024-20411 – Cisco NX-OS Bash Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2024-20411
A vulnerability in Cisco NX-OS Software could allow an authenticated, local attacker with privileges to access the Bash shell to execute arbitrary code as root on an affected device. This vulnerability is due to insufficient security restrictions when executing commands from the Bash shell. An attacker with privileges to access the Bash shell could exploit this vulnerability by executing a specific crafted command on the underlying operating system. A successful exploit could allow the attacker to execute arbitrary code with the privileges of root. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-bshacepe-bApeHSx7 • CWE-267: Privilege Defined With Unsafe Actions •
CVSS: 6.7EPSS: 0%CPEs: 56EXPL: 0CVE-2024-20413 – Cisco NX-OS Bash Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2024-20413
A vulnerability in Cisco NX-OS Software could allow an authenticated, local attacker with privileges to access the Bash shell to elevate privileges to network-admin on an affected device. This vulnerability is due to insufficient security restrictions when executing application arguments from the Bash shell. An attacker with privileges to access the Bash shell could exploit this vulnerability by executing crafted commands on the underlying operating system. A successful exploit could allow the attacker to create new users with the privileges of network-admin. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-bshacepe-bApeHSx7 • CWE-862: Missing Authorization •

https://notcve.org/view.php?id=CVE-2024-20294
A vulnerability in the Link Layer Discovery Protocol (LLDP) feature of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of specific fields in an LLDP frame. An attacker could exploit this vulnerability by sending a crafted LLDP packet to an interface of an affected device and having an authenticated user retrieve LLDP statistics from the affected device through CLI show commands or Simple Network Management Protocol (SNMP) requests. A successful exploit could allow the attacker to cause the LLDP service to crash and stop running on the affected device. In certain situations, the LLDP crash may result in a reload of the affected device. Note: LLDP is a Layer 2 link protocol. To exploit this vulnerability, an attacker would need to be directly connected to an interface of an affected device, either physically or logically (for example, through a Layer 2 Tunnel configured to transport the LLDP protocol). • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-lldp-dos-z7PncTgt • CWE-805: Buffer Access with Incorrect Length Value •
CVSS: 5.8EPSS: 0%CPEs: 3EXPL: 1CVE-2024-20291
https://notcve.org/view.php?id=CVE-2024-20291
A vulnerability in the access control list (ACL) programming for port channel subinterfaces of Cisco Nexus 3000 and 9000 Series Switches in standalone NX-OS mode could allow an unauthenticated, remote attacker to send traffic that should be blocked through an affected device. This vulnerability is due to incorrect hardware programming that occurs when configuration changes are made to port channel member ports. An attacker could exploit this vulnerability by attempting to send traffic through an affected device. A successful exploit could allow the attacker to access network resources that should be protected by an ACL that was applied on port channel subinterfaces. Una vulnerabilidad en la programación de la lista de control de acceso (ACL) para las subinterfaces del canal de puerto de los conmutadores Cisco Nexus de las series 3000 y 9000 en modo NX-OS independiente podría permitir que un atacante remoto no autenticado envíe tráfico que debería bloquearse a través de un dispositivo afectado. Esta vulnerabilidad se debe a una programación de hardware incorrecta que ocurre cuando se realizan cambios de configuración en los puertos miembros del canal de puertos. • https://github.com/Instructor-Team8/CVE-2024-20291-POC https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nxos-po-acl-TkyePgvL • CWE-284: Improper Access Control •
