Container capabilities must only include NET_BIND_SERVICE

Property Value
Language terraform
Severity low

Description

The container is configured with excessive Linux capabilities, rather than dropping all by default and only allowing NET_BIND_SERVICE. This increases the container's privileges beyond what is necessary for binding to low ports.

Impact

If exploited, attackers could leverage unnecessary capabilities to escalate privileges or compromise the host, increasing the risk of container breakout or unauthorized access to system resources.

Resolution

Set 'spec.containers[].securityContext.capabilities.drop' to 'ALL' and only add 'NET_BIND_SERVICE' to 'spec.containers[].securityContext.capabilities.add'.
