| 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. | |||||
| CVE-2021-1438 | 1 Cisco | 1 Wide Area Application Services | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| A vulnerability in Cisco Wide Area Application Services (WAAS) Software could allow an authenticated, local attacker to gain access to sensitive information on an affected device. The vulnerability is due to improper input validation and authorization of specific commands that a user can execute within the CLI. An attacker could exploit this vulnerability by authenticating to an affected device and issuing a specific set of commands. A successful exploit could allow the attacker to read arbitrary files that they originally did not have permissions to access. | |||||
| CVE-2021-1437 | 1 Cisco | 14 1100 Integrated Services Router, Aironet 1540, Aironet 1560 and 11 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| A vulnerability in the FlexConnect Upgrade feature of Cisco Aironet Series Access Points Software could allow an unauthenticated, remote attacker to obtain confidential information from an affected device. This vulnerability is due to an unrestricted Trivial File Transfer Protocol (TFTP) configuration. An attacker could exploit this vulnerability by sending a specific TFTP request to an affected device.

| CVE-2021-1433 | 1 Cisco | 1 Ios Xe | 2024-11-21 | 9.3 HIGH | 8.1 HIGH |
| A vulnerability in the vDaemon process in Cisco IOS XE SD-WAN Software could allow an unauthenticated, remote attacker to cause a buffer overflow on an affected device. This vulnerability is due to insufficient bounds checking when the device processes traffic. An attacker could exploit this vulnerability by sending crafted traffic to the device. The attacker must have a man-in-the-middle position between Cisco vManage and an associated device that is running an affected version of Cisco IOS XE SD-WAN Software. An exploit could allow the attacker to conduct a controllable buffer overflow attack (and possibly execute arbitrary commands as the root user) or cause a device reload, resulting in a denial of service (DoS) condition. | |||||
| CVE-2021-1432 | 1 Cisco | 2 Ios Xe, Ios Xe Sd-wan | 2024-11-21 | 6.9 MEDIUM | 7.3 HIGH |
| A vulnerability in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system as the root user. The attacker must be authenticated on the affected device as a low-privileged user to exploit this vulnerability. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by injecting arbitrary commands to a file as a lower-privileged user. The commands are then executed on the device by the root user. A successful exploit could allow the attacker to execute arbitrary commands as the root user. | |||||
