| CVE-2021-1449 | 1 Cisco | 14 1100 Integrated Services Router, Aironet 1540, Aironet 1560 and 11 more | 2024-11-21 | 4.6 MEDIUM | 6.7 MEDIUM |
| A vulnerability in the boot logic of Cisco Access Points Software could allow an authenticated, local attacker to execute unsigned code at boot time. The vulnerability is due to an improper check that is performed by the area of code that manages system startup processes. An attacker could exploit this vulnerability by modifying a specific file that is stored on the system, which would allow the attacker to bypass existing protections. 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. Note: To exploit this vulnerability, the attacker would need to have access to the development shell (devshell) on the device. | |||||

| CVE-2021-1446 | 1 Cisco | 1 Ios Xe | 2024-11-21 | 7.1 HIGH | 8.6 HIGH |
| A vulnerability in the DNS application layer gateway (ALG) functionality used by Network Address Translation (NAT) in Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to a logic error that occurs when an affected device inspects certain DNS packets. An attacker could exploit this vulnerability by sending crafted DNS packets through an affected device that is performing NAT for DNS packets. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition on an affected device. The vulnerability can be exploited only by traffic that is sent through an affected device via IPv4 packets. The vulnerability cannot be exploited via IPv6 traffic. | |||||
| CVE-2021-1445 | 1 Cisco | 2 Adaptive Security Appliance Software, Firepower Threat Defense | 2024-11-21 | 5.0 MEDIUM | 8.6 HIGH |
| Multiple vulnerabilities in Cisco Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. These vulnerabilities are due to lack of proper input validation of the HTTPS request. An attacker could exploit these vulnerabilities by sending a crafted HTTPS request to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition.

| CVE-2021-1443 | 1 Cisco | 1 Ios Xe | 2024-11-21 | 8.5 HIGH | 5.5 MEDIUM |
| A vulnerability in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker to execute arbitrary code with root privileges on the underlying operating system of an affected device. The vulnerability exists because the affected software improperly sanitizes values that are parsed from a specific configuration file. An attacker could exploit this vulnerability by tampering with a specific configuration file and then sending an API call. A successful exploit could allow the attacker to inject arbitrary code that would be executed on the underlying operating system of the affected device. To exploit this vulnerability, the attacker would need to have a privileged set of credentials to the device. | |||||
| CVE-2021-1442 | 1 Cisco | 1 Ios Xe | 2024-11-21 | 6.9 MEDIUM | 7.8 HIGH |
| A vulnerability in a diagnostic command for the Plug-and-Play (PnP) subsystem of Cisco IOS XE Software could allow an authenticated, local attacker to elevate privileges to the level of an Administrator user (level 15) on an affected device. The vulnerability is due to insufficient protection of sensitive information. An attacker with low privileges could exploit this vulnerability by issuing the diagnostic CLI show pnp profile when a specific PnP listener is enabled on the device. A successful exploit could allow the attacker to obtain a privileged authentication token. This token can be used to send crafted PnP messages and execute privileged commands on the targeted system. | |||||
| CVE-2021-1441 | 1 Cisco | 3 Esr6300, Ios Xe, Ir1101 | 2024-11-21 | 7.2 HIGH | 6.7 MEDIUM |
| A 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. | |||||
| CVE-2021-1439 | 1 Cisco | 13 1100 Integrated Services Router, Aironet 1540, Aironet 1560 and 10 more | 2024-11-21 | 3.3 LOW | 7.4 HIGH |
| A vulnerability in the multicast DNS (mDNS) gateway feature of Cisco Aironet Series Access Points Software 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 incoming mDNS traffic. An attacker could exploit this vulnerability by sending a crafted mDNS packet to an affected device through a wireless network that is configured in FlexConnect local switching mode or through a wired network on a configured mDNS VLAN. A successful exploit could allow the attacker to cause the access point (AP) to reboot, resulting in a DoS condition. | |||||
