CVE-2025-20119

Service interruption via system file handling race

Published Feb 26, 2025 · Updated Mar 3, 2025

A race condition in Cisco APIC allows local users to overwrite critical system files and interrupt controller service. System file permission handling races with specific filesystem operations, permitting protected files to be overwritten. Valid administrative credentials and local access are required; successful exploitation leaves the device inconsistent and interrupts APIC service.
