An attacker could exploit this vulnerability by interrupting the boot process and executing specific commands to bypass the Cisco Secure Boot validation checks and load an image that has been tampered with. This image would have been previously downloaded onto the targeted device. A successful exploit could allow the attacker to load the image once. The Cisco Secure Boot functionality is not permanently compromised.\r\n\r\nCisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.\n\n## Vendor advisories\n\n- **cisco-sa-ap-secureboot-bypass-zT5vJkSD** · Cisco · affected: Cisco IOS XE Software, Cisco Aironet Access Point Software, Cisco Business Wireless Access Point Software, Cisco Aironet Access Point Software (IOS XE Controller) · updated 2024-03-27 · [advisory](https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-secureboot-bypass-zT5vJkSD)\n\n**Cisco Access Point Software Secure Boot Bypass Vulnerability**.
