https://notcve.org/view.php?id=CVE-2023-20082
23 Mar 2023 — A vulnerability in Cisco IOS XE Software for Cisco Catalyst 9300 Series Switches could allow an authenticated, local attacker with level-15 privileges or an unauthenticated attacker with physical access to the device to execute persistent code at boot time and break the chain of trust. This vulnerability is due to errors that occur when retrieving the public release key that is used for image signature verification. An attacker could exploit this vulnerability by modifying specific variables in the Serial P... • https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-c9300-spi-ace-yejYgnNQ • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

CVE-2023-20097 – Cisco Access Point Software Command Injection Vulnerability
https://notcve.org/view.php?id=CVE-2023-20097
23 Mar 2023 — 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') •
