Cisco Multiple Operating Systems Unidirectional Link Detection Denial of Service (CVE-2021-34714)

A vulnerability in the Unidirectional Link Detection UDLD feature of Cisco FXOS Software, Cisco IOS Software, Cisco IOS XE Software, Cisco IOS XR Software, and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause an affected device to reload. This vulnerability is due t...

CVE-2021-34714 Multiple Cisco Operating Systems Unidirectional Link Detection Denial of Service Vulnerability

A vulnerability in the Unidirectional Link Detection UDLD feature of Cisco FXOS Software, Cisco IOS Software, Cisco IOS XE Software, Cisco IOS XR Software, and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause an affected device to reload. This vulnerability is due t...

CVE-2021-34714

CVE-2021-34714 affects Cisco FXOS, IOS, IOS XE/XR, and NX-OS UDLD implementations. The root cause is improper input validation of UDLD packets, enabling an unauthenticated, adjacent attacker to trigger a device reload and DoS; on IOS XR the impact is limited to reloading the UDLD process. The vul...

Cisco FXOS Software Unidirectional Link Detection DoS / Code Execution (cisco-sa-nxos-udld-rce-xetH6w35)

An arbitrary code execution or denial of service DoS vulnerability exists in Unidirectional Link Detection UDLD feature of Cisco FXOS Software due to insufficient input validation. An unauthenticated, adjacent attacker can exploit this issue by sending crafted Cisco UDLD protocol packets to a...
