NVD Description

Note: Versions mentioned in the description apply only to the upstream rubygem-json package and not the rubygem-json package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

Ruby before 2.4.3 allows Net::FTP command injection. Net::FTP#get, getbinaryfile, gettextfile, put, putbinaryfile, and puttextfile use Kernel#open to open a local file. If the localfile argument starts with the "|" pipe character, the command following the pipe character is executed. The default value of localfile is File.basename(remotefile), so malicious FTP servers could cause arbitrary command execution.
