Uncontrolled Resource Consumption

CVE-2023-40180

Severity High
Score 7.5/10

Summary

The package silverstripe-graphql is a package that serves Silverstripe data in GraphQL representations. An attacker could use a recursive graphql query to execute a Distributed Denial of Service attack (DDOS attack) against a website in versions 3.0.0-rc1 through 3.8.1, 4.0.0-alpha1 through 4.1.2, 4.2.0 through 4.2.4, 4.3.0-rc1 through 4.3.3, 5.0.0-alpha1 through 5.0.2, and 5.1.0-beta1 through 5.1.0-rc1. This mostly affects websites with publicly exposed graphql schemas. If your Silverstripe CMS project does not expose a public-facing graphql schema, a user account is required to trigger the DDOS attack. If your site is hosted behind a content delivery network (CDN), such as Imperva or CloudFlare, this may further mitigate the risk. Users are advised to upgrade. There are no known workarounds for this vulnerability.

CWE-400 - Uncontrolled resource consumption

An uncontrolled resource allocation attack (also known as resource exhaustion attack) triggers unauthorized overconsumption of the limited resources in an application, such as memory, file system storage, database connection pool entries, and CPU. This may lead to denial of service for valid users and degradation of the application's functionality as well as that of the host operating system.
