https://notcve.org/view.php?id=CVE-2023-20065
A vulnerability in the Cisco IOx application hosting subsystem of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to root on an affected device. This vulnerability is due to insufficient restrictions on the hosted application. An attacker could exploit this vulnerability by logging in to and then escaping the Cisco IOx application container. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system with root privileges. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iox-priv-escalate-Xg8zkyPk • CWE-284: Improper Access Control •
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 •

https://notcve.org/view.php?id=CVE-2023-20029
A vulnerability in the Meraki onboarding feature of Cisco IOS XE Software could allow an authenticated, local attacker to gain root level privileges on an affected device. This vulnerability is due to insufficient memory protection in the Meraki onboarding feature of an affected device. An attacker could exploit this vulnerability by modifying the Meraki registration parameters. A successful exploit could allow the attacker to elevate privileges to root. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-priv-esc-sABD8hcU • CWE-122: Heap-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2023-20056
A vulnerability in the management CLI of Cisco access point (AP) software could allow an authenticated, local attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to insufficient input validation of commands supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input to the affected command. A successful exploit could allow the attacker to cause an affected device to reload spontaneously, resulting in a DoS condition. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-cli-dos-tc2EKEpu • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
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 •
