CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:HA vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco IOS XE Software could allow an authenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. This vulnerability is due to improper error handling when parsing SNMP requests. This vulnerability affects all versions of SNMP — Versions 1, 2c, and 3. An attacker could exploit this vulnerability by sending a malformed SNMP request to an affected device. A successful exploit could allow the attacker to cause the device to reload unexpectedly. The attacker must have the SNMPv1 or v2c read-only or read-write community string or valid SNMPv3 user credentials on the affected device.
Multiple vulnerabilities have been discovered in Cisco products, including SD-WAN and networking equipment. These vulnerabilities can lead to remote code execution, denial-of-service attacks, and data confidentiality bre…
