CVE-2021-1441 Detail
Modified
This CVE record has been updated after NVD enrichment efforts were completed. Enrichment data supplied by the NVD may require amendment due to these changes. DescriptionA vulnerability in the hardware initialization routines of Cisco IOS XE Software for Cisco 1100 Series Industrial Integrated Services Routers and Cisco ESR6300 Embedded Series Routers could allow an authenticated, local attacker to execute unsigned code at system boot time. This vulnerability is due to incorrect validations of parameters passed to a diagnostic script that is executed when the device boots up. An attacker could exploit this vulnerability by tampering with an executable file stored on a device. A successful exploit could allow the attacker to execute unsigned code at boot time and bypass the software image verification check part of the secure boot process of an affected device. To exploit this vulnerability, the attacker would need administrative level credentials (level 15) on the device. Metrics
