The vCenter VAMI service must set the encoding for all text mime types to UTF-8.

An XCCDF Rule

Description

<VulnDiscussion>Invalid user input occurs when a user inserts data or characters into a hosted application's data entry field and the hosted application is unprepared to process that data. This results in unanticipated application behavior, potentially leading to an application compromise. Invalid user input is one of the primary methods employed when attempting to compromise an application. An attacker can also enter Unicode into hosted applications in an effort to break out of the document home or root home directory or to bypass security checks.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Navigate to and open:

/var/lib/vmware/cap-lighttpd/lighttpd.conf

Navigate to the "mimetype.assign" block.
Replace all the mappings whose assigned type is "text/*" with mappings for UTF-8 encoding. For example:

  ".log"          =>      "text/plain; charset=utf-8",
  ".conf"         =>      "text/plain; charset=utf-8",
  ".text"         =>      "text/plain; charset=utf-8",
  ".txt"          =>      "text/plain; charset=utf-8",
  ".spec"         =>      "text/plain; charset=utf-8",
  ".dtd"          =>      "text/xml; charset=utf-8",
  ".xml"          =>      "text/xml; charset=utf-8",

Restart the service with the following command:

# systemctl restart cap-lighttpd
