VAR-201401-0341
Vulnerability from variot - Updated: 2023-12-18 13:34The Label Distribution Protocol (LDP) functionality in Cisco NX-OS allows remote attackers to cause a denial of service (temporary LDP session outage) via LDP discovery traffic containing malformed Hello messages, aka Bug ID CSCul88851. Cisco NX-OS software is a data center-level operating system that reflects modular design, resiliency, and maintainability. The vulnerability is due to a vulnerability in analytic malformed LDP Hello messages, which an attacker could send to the affected device to trigger the vulnerability. Cisco NX-OS is prone to a remote denial-of-service vulnerability. Successfully exploiting this issue allows remote attackers to cause denial-of-service conditions. This issue is being tracked by Cisco Bug ID CSCul88851. Cisco NX-OS is a data center-oriented operating system developed by Cisco
