CVSS: 8.6EPSS: 0%CPEs: 224EXPL: 0CVE-2023-20027 – Cisco IOS XE Software Virtual Fragmentation Reassembly Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2023-20027
A vulnerability in the implementation of the IPv4 Virtual Fragmentation Reassembly (VFR) feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper reassembly of large packets that occurs when VFR is enabled on either a tunnel interface or on a physical interface that is configured with a maximum transmission unit (MTU) greater than 4,615 bytes. An attacker could exploit this vulnerability by sending fragmented packets through a VFR-enabled interface on an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipv4-vfr-dos-CXxtFacb • CWE-416: Use After Free •
CVSS: 7.4EPSS: 0%CPEs: 48EXPL: 0CVE-2023-20067 – Cisco IOS XE Software for Wireless LAN Controllers HTTP Client Profiling Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2023-20067
A vulnerability in the HTTP-based client profiling feature of Cisco IOS XE Software for Wireless LAN Controllers (WLCs) 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 of received traffic. An attacker could exploit this vulnerability by sending crafted traffic through a wireless access point. A successful exploit could allow the attacker to cause CPU utilization to increase, which could result in a DoS condition on an affected device and could cause new wireless client associations to fail. Once the offending traffic stops, the affected system will return to an operational state and new client associations will succeed. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ewlc-dos-wFujBHKw • CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2022-20920
A vulnerability in the SSH implementation of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to cause an affected device to reload. This vulnerability is due to improper handling of resources during an exceptional situation. An attacker could exploit this vulnerability by continuously connecting to an affected device and sending specific SSH requests. A successful exploit could allow the attacker to cause the affected device to reload. Una vulnerabilidad en la implementación de SSH del software Cisco IOS y del software Cisco IOS XE podría permitir que un atacante remoto autenticado causara la recarga de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ssh-excpt-dos-FzOBQTnk • CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 7.4EPSS: 0%CPEs: 2EXPL: 0CVE-2019-12665 – Cisco IOS and IOS XE Software HTTP Client Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2019-12665
A vulnerability in the HTTP client feature of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to read and modify data that should normally have been sent via an encrypted channel. The vulnerability is due to TCP port information not being considered when matching new requests to existing, persistent HTTP connections. An attacker could exploit this vulnerability by acting as a man-in-the-middle and then reading and/or modifying data that should normally have been sent through an encrypted channel. Una vulnerabilidad en la funcionalidad HTTP client de los Software Cisco IOS y IOS XE, podría permitir a un atacante remoto no autenticado leer y modificar datos que normalmente deberían haber sido enviados por medio de un canal encriptado. La vulnerabilidad es debido a que no ha sido considerada la información del puerto TCP al hacer coincidir nuevas peticiones con conexiones HTTP persistentes y existentes. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-http-client • CWE-399: Resource Management Errors •
CVSS: 8.6EPSS: 0%CPEs: 3EXPL: 0CVE-2018-15377 – Cisco IOS and IOS XE Software Plug and Play Agent Memory Leak Vulnerability
https://notcve.org/view.php?id=CVE-2018-15377
A vulnerability in the Cisco Network Plug and Play agent, also referred to as the Cisco Open Plug-n-Play agent, of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a memory leak on an affected device. The vulnerability is due to insufficient input validation by the affected software. An attacker could exploit this vulnerability by sending invalid data to the Cisco Network Plug and Play agent on an affected device. A successful exploit could allow the attacker to cause a memory leak on the affected device, which could cause the device to reload. Una vulnerabilidad en el agente Cisco Network Plug and Play también llamado agente Cisco Open Plug-n-Play, de Cisco IOS Software y Cisco IOS XE Software podría permitir que un atacante remoto no autenticado provoque una fuga de memoria en un dispositivo afectado. • https://ics-cert.us-cert.gov/advisories/ICSA-19-094-02 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-pnp-memleak • CWE-400: Uncontrolled Resource Consumption CWE-401: Missing Release of Memory after Effective Lifetime •
