Cisco Systems on Wednesday issued patches to address a critical security vulnerability affecting the Application Policy Infrastructure Controller (APIC) interface used in its Nexus 9000 Series Switches that could be potentially abused to read or write arbitrary files on a vulnerable system.
Tracked as CVE-2021-1577 (CVSS score: 9.1), the issue — which is due to improper access control — could enable an unauthenticated, remote attacker to upload a file to the appliances. ” A successful exploit could allow the attacker to read or write arbitrary files on an affected device,” the company said in an advisory.
