New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 6.7
SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionEtienne Stalmans from the Heroku product security team reports :
There is a command injection vulnerability in Net::FTP bundled with Ruby.
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.
SolutionUpdate the affected packages.
