VCPF-70-000012 - Performance Charts must have Multipurpose Internet Mail Extensions (MIMEs) that invoke operating system shell programs disabled.

Information

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.

Solution

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>
