OpenShift must set the sticky bit for world-writable directories.
An XCCDF Rule
Description
<VulnDiscussion>Removing world-writable permissions or setting the sticky bit helps enforce access control on directories within the OpenShift platform. World-writable permissions allow any user to modify or delete files within the directory, which can introduce security risks. By removing these permissions or setting the sticky bit, OpenShift restricts modifications to the directory's owner and prevents unauthorized or unintended changes by other users.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
