Overview

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling when processing malformed modbus traffic including long-lived transactions, which can accumulate alerts in a flow. The modbus parser is disabled by default, so this is only exploitable if the application is using a non-default configuration.

Workaround

This vulnerability can be avoided by lowering stream.reassembly.depth.
