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-2023-20097
A vulnerability in Cisco access points (AP) software could allow an authenticated, local attacker to inject arbitrary commands and execute them with root privileges. This vulnerability is due to improper input validation of commands that are issued from a wireless controller to an AP. An attacker with Administrator access to the CLI of the controller could exploit this vulnerability by issuing a command with crafted arguments. A successful exploit could allow the attacker to gain full root access on the AP. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-aironetap-cmdinj-6bjT4FL8 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
CVSS: 8.8EPSS: 0%CPEs: 47EXPL: 0CVE-2023-20076 – Cisco IOx Application Hosting Environment Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2023-20076
A vulnerability in the Cisco IOx application hosting environment could allow an authenticated, remote attacker to execute arbitrary commands as root on the underlying host operating system. This vulnerability is due to incomplete sanitization of parameters that are passed in for activation of an application. An attacker could exploit this vulnerability by deploying and activating an application in the Cisco IOx application hosting environment with a crafted activation payload file. A successful exploit could allow the attacker to execute arbitrary commands as root on the underlying host operating system. • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iox-8whGn5dL • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-233: Improper Handling of Parameters •

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 •
