Vulnerability from variot
A vulnerability in the Image Verification feature of Cisco IOS XE Software could allow an authenticated, local attacker to install and boot a malicious software image or execute unsigned binaries on an affected device. The vulnerability exists because, under certain circumstances, an affected device can be configured to not verify the digital signatures of system image files during the boot process. An attacker could exploit this vulnerability by abusing a specific feature that is part of the device boot process. A successful exploit could allow the attacker to install and boot a malicious software image or execute unsigned binaries on the targeted device. Cisco IOS XE The software contains a vulnerability related to digital signature verification.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Cisco Catalyst 3850 Series Switches and Cisco Catalyst 9300 Series Switches are both Cisco products. Cisco Catalyst 3850 Series Switches is a 3850 series switch. Cisco Catalyst 9300 Series Switches is a 9300 series switch. IOS XE is a set of operating systems developed for its network equipment

"data": "A vulnerability in the Image Verification feature of Cisco IOS XE Software could allow an authenticated, local attacker to install and boot a malicious software image or execute unsigned binaries on an affected device. The vulnerability exists because, under certain circumstances, an affected device can be configured to not verify the digital signatures of system image files during the boot process. An attacker could exploit this vulnerability by abusing a specific feature that is part of the device boot process. A successful exploit could allow the attacker to install and boot a malicious software image or execute unsigned binaries on the targeted device. Cisco IOS XE The software contains a vulnerability related to digital signature verification.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Cisco Catalyst 3850 Series Switches and Cisco Catalyst 9300 Series Switches are both Cisco products. Cisco Catalyst 3850 Series Switches is a 3850 series switch. Cisco Catalyst 9300 Series Switches is a 9300 series switch. IOS XE is a set of operating systems developed for its network equipment",
