Test ID: | 1.3.6.1.4.1.25623.1.0.105705 |
Category: | CISCO |
Title: | Cisco NX-OS Software Link Layer Discovery Protocol Denial of Service Vulnerability |
Summary: | A vulnerability in the Link Layer Discovery Protocol (LLDP) code of Cisco NX-OS Software could allow; an unauthenticated, adjacent attacker to crash an affected device.;; The vulnerability is due to an error in parsing a malformed LLDP packet. An attacker could exploit; this vulnerability by sending a crafted, malformed LLDP packet to an interface enabled for LLDP; packet processing.;; Cisco has confirmed the vulnerability and released software updates.;; To exploit this vulnerability, an attacker must be on the same broadcast or collision domain as the; targeted device. This access requirement reduces the likelihood of a successful exploit.;; Cisco indicates through the CVSS score that functional exploit code exists. However, the code is not; known to be publicly available. |
Description: | Summary: A vulnerability in the Link Layer Discovery Protocol (LLDP) code of Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to crash an affected device. The vulnerability is due to an error in parsing a malformed LLDP packet. An attacker could exploit this vulnerability by sending a crafted, malformed LLDP packet to an interface enabled for LLDP packet processing. Cisco has confirmed the vulnerability and released software updates. To exploit this vulnerability, an attacker must be on the same broadcast or collision domain as the targeted device. This access requirement reduces the likelihood of a successful exploit. Cisco indicates through the CVSS score that functional exploit code exists. However, the code is not known to be publicly available. Solution: See the referenced vendor advisory for a solution. CVSS Score: 6.1 CVSS Vector: AV:A/AC:L/Au:N/C:N/I:N/A:C |
