Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Github.com/tendermint/tendermint, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Due to support of Gzip compression in request bodies, as well as a lack of limiting response body sizes, a malicious server can cause a client to consume a significant amount of system resources, which may be used as a denial of service vector.
