A vulnerability in the IKEv1 fragmentation code of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a heap overflow, resulting in an affected device reloading. This vulnerability exists because crafted, fragmented IKEv1 packets are not properly reassembled. An attacker could exploit this vulnerability by sending crafted UDP packets to an affected system. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Note: Only traffic that is directed to the affected system can be used to exploit this vulnerability. This vulnerability can be triggered by IPv4 and IPv6 traffic. Una vulnerabilidad en el código de fragmentación IKEv1 del software Cisco IOS y del software Cisco IOS XE podría permitir que un atacante remoto no autenticado provoque un desbordamiento de almacenamiento dinámico, lo que provocaría la recarga del dispositivo afectado. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ikev1-NO2ccFWz • CWE-121: Stack-based Buffer Overflow •

A vulnerability in the IKEv1 fragmentation code of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a heap underflow, resulting in an affected device reloading. This vulnerability exists because crafted, fragmented IKEv1 packets are not properly reassembled. An attacker could exploit this vulnerability by sending crafted UDP packets to an affected system. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. Note: Only traffic that is directed to the affected system can be used to exploit this vulnerability. This vulnerability can be triggered by IPv4 and IPv6 traffic..

https://notcve.org/view.php?id=CVE-2024-20312
A vulnerability in the Intermediate System-to-Intermediate System (IS-IS) protocol of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation when parsing an ingress IS-IS packet. An attacker could exploit this vulnerability by sending a crafted IS-IS packet to an affected device after forming an adjacency. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a denial of service (DoS) condition. Note: The IS-IS protocol is a routing protocol. To exploit this vulnerability, an attacker must be Layer 2-adjacent to the affected device and have formed an adjacency. Una vulnerabilidad en el protocolo de sistema intermedio a sistema intermedio (IS-IS) del software Cisco IOS y del software Cisco IOS XE podría permitir que un atacante adyacente no autenticado cause una condición de denegación de servicio (DoS) en un dispositivo afectado. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-isis-sGjyOUHX • CWE-476: NULL Pointer Dereference •

A vulnerability in the Locator ID Separation Protocol (LISP) feature of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. This vulnerability is due to the incorrect handling of LISP packets. An attacker could exploit this vulnerability by sending a crafted LISP packet to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a denial of service (DoS) condition. Note: This vulnerability could be exploited over either IPv4 or IPv6 transport. Una vulnerabilidad en la función del Protocolo de separación de ID del localizador (LISP) del software Cisco IOS y del software Cisco IOS XE podría permitir que un atacante remoto no autenticado provoque la recarga de un dispositivo afectado. Esta vulnerabilidad se debe al manejo incorrecto de los paquetes LISP. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-lisp-3gYXs3qP • CWE-674: Uncontrolled Recursion •
CVSS: 6.6EPSS: 0%CPEs: 1040EXPL: 0CVE-2023-20109 – Cisco IOS and IOS XE Group Encrypted Transport VPN Out-of-Bounds Write Vulnerability
https://notcve.org/view.php?id=CVE-2023-20109
A vulnerability in the Cisco Group Encrypted Transport VPN (GET VPN) feature of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker who has administrative control of either a group member or a key server to execute arbitrary code on an affected device or cause the device to crash. This vulnerability is due to insufficient validation of attributes in the Group Domain of Interpretation (GDOI) and G-IKEv2 protocols of the GET VPN feature. An attacker could exploit this vulnerability by either compromising an installed key server or modifying the configuration of a group member to point to a key server that is controlled by the attacker. A successful exploit could allow the attacker to execute arbitrary code and gain full control of the affected system or cause the affected system to reload, resulting in a denial of service (DoS) condition. For more information, see the Details ["#details"] section of this advisory. Una vulnerabilidad en la función Cisco Group Encrypted Transport VPN (GET VPN) del software Cisco IOS y del software Cisco IOS XE podría permitir que un atacante remoto autenticado que tiene control administrativo de un miembro del grupo o de un servidor de claves ejecute código arbitrario en un dispositivo afectado o haga que el dispositivo se bloquee. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-getvpn-rce-g8qR68sx • CWE-787: Out-of-bounds Write •
