Red Hat Security Advisory 2023-5764-01 - Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language. Issues addressed include a denial of service vulnerability.
### Impact An attacker could use a recursive graphql query to execute a Distributed Denial of Service attack (DDOS attack) against a website. 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. The fix includes some new configuration options which you might want to tweak for your project, based on your own requirements. See the documentation in the references for details. ### Patches Patched in [3.8.2](https://github.com/silverstripe/silverstripe-graphql/releases/tag/3.8.2), [4.1.3](https://github.com/silverstripe/silverstripe-graphql/releases/tag/4.1.3), [4.2.5](https://github.com/silverstripe/silverstripe-graphql/releases/tag/4.2.5), [4.3.4](https://github.com/silverstripe/silverstripe-graphql/releases/...
### Impact Envoy and Go HTTP/2 protocol stack is vulnerable to the "Rapid Reset" class of exploits, which send a sequence of HEADERS frames optionally followed by RST_STREAM frames. This can be exercised if you use the builtin gateway and receive untrusted http2 traffic. ### Patches https://github.com/kumahq/kuma/pull/8023 https://github.com/kumahq/kuma/pull/8001 https://github.com/kumahq/kuma/pull/8034 ### Workarounds Disable http2 on the gateway listener with a MeshProxyPatch or ProxyTemplate. ### References https://github.com/advisories/GHSA-qppj-fm5r-hxr3 https://github.com/golang/go/issues/63417 https://github.com/envoyproxy/envoy/security/advisories/GHSA-jhv4-f7mr-xx76 https://cloud.google.com/blog/products/identity-security/how-it-works-the-novel-http2-rapid-reset-ddos-attack https://www.nginx.com/blog/http-2-rapid-reset-attack-impacting-f5-nginx-products/?sf269548684=1 https://www.envoyproxy.io/docs/envoy/latest/configuration/best_practices/edge
silverstripe-graphql is a package which 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. 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. This issue has been addressed in versions 3.8.2, 4.1.3, 4.2.5, 4.3.4, and 5.0.3. Users are advised to upgrade. There are no known workarounds for this vulnerability.
