CVE-2016-11056Public exploitNetwork attack vector

Unauthenticated root command execution via bfile injection

Published Apr 28, 2020 · Updated Aug 6, 2024

Command injection in NETGEAR ReadyNAS Surveillance through 1.1.1-3-armel or 1.4.1-3-amd64 allows remote attackers to gain root access. The unauthenticated cgi_system saveconfig handler inserts the user-controlled bfile POST value into a shell command without validation. Network access to the application's HTTP interface is sufficient to execute arbitrary commands as root and read configuration files.
