CVE-2012-4122
The CLI parser in Cisco NX-OS allows local users to bypass intended access restrictions, and overwrite or create arbitrary files, via shell output redirection, aka Bug IDs CSCts56672 and CSCts56669.
Does this matter?
Lower severity and a low EPSS score (0.31%). Track it; it rarely justifies an emergency change on its own.
