### 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/...

Although there is public research on Direct Composition, only a few discuss fuzzing this feature, and none, to our knowledge, that covers snapshot fuzzing.

View CSAF 1. EXECUTIVE SUMMARY CVSS v3 8.2 ATTENTION: Exploitable remotely/low attack complexity Vendor: Rockwell Automation Equipment: FactoryTalk Linx Vulnerability: Improper Input Validation 2. RISK EVALUATION Successful exploitation of this vulnerability could lead to information disclosure or a denial-of-service condition. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS The following versions of Rockwell products are affected: FactoryTalk Linx: v6.20 and prior 3.2 Vulnerability Overview 3.2.1 IMPROPER INPUT VALIDATION CWE-20 FactoryTalk Linx, in the Rockwell Automation PanelView Plus, allows an unauthenticated threat actor to read data from memory via crafted malicious packets. Sending a size larger than the buffer size results in leakage of data from memory resulting in an information disclosure. If the size is large enough, it causes communications over the common industrial protocol to become unresponsive to any type of packet, resulting in a denial-of-service to FactoryTalk Linx ov...
