Description
MIME mappings tell Performance Charts what type of program various file types and extensions are and what external utilities or programs are needed to execute the file type. By ensuring various shell script MIME types are not included in "web.xml", the server is protected against malicious users tricking the server into executing shell command files.
ℹ️ Check
At the command prompt, run the following command: # grep -En '(x-csh<)|(x-sh<)|(x-shar<)|(x-ksh<)' /usr/lib/vmware-perfcharts/tc-instance/conf/web.xml If the command produces any output, this is a finding.
✔️ Fix
Navigate to and open: /usr/lib/vmware-perfcharts/tc-instance/conf/web.xml Remove any and all of the following nodes lines: <mime-type>application/x-csh</mime-type> <mime-type>application/x-shar</mime-type> <mime-type>application/x-sh</mime-type> <mime-type>application/x-ksh</mime-type> Restart the service with the following command: # vmon-cli --restart perfcharts Note: Delete the entire mime-mapping node for the target mime-type. Example: <mime-mapping> <extension>sh</extension> <mime-type>application/x-sh</mime-type> </mime-mapping>
