4,227 CVEs • Abstraction: Base • Likelihood of Exploit: High

Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.

A vulnerability in the Cisco&nbsp;Discovery Protocol implementation for Cisco&nbsp;IOS XR Software could allow an unauthenticated, adjacent attacker to cause the Cisco&nbsp;Discovery Protocol process to reload on an affected device. This vulnerability is due to a heap buffer overflow in certain Cisco&nbsp;Discovery Protocol messages. An attacker could exploit this vulnerability by sending a malicious Cisco&nbsp;Discovery Protocol packet to an affected device. A successful exploit could allow the attacker to cause a heap overflow, which could cause the Cisco&nbsp;Discovery Protocol process to reload on the device. The bytes that can be written in the buffer overflow are restricted, which limits remote code execution.Note: Cisco&nbsp;Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent). &nbsp;Cisco&nbsp;has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.This advisory is part of the September 2022 release of the Cisco&nbsp;IOS XR Software Security Advisory Bundled Publication. For a complete list of the advisories and links to them, see .Show less
