CVSS: 10.0EPSS: 0%CPEs: 2EXPL: 1CVE-2023-38495 – Crossplane vulnerable to possible image tampering from missing image validation for Packages
https://notcve.org/view.php?id=CVE-2023-38495
27 Jul 2023 — Crossplane is a framework for building cloud native control planes without needing to write code. In versions prior to 1.11.5, 1.12.3, and 1.13.0, Crossplane's image backend does not validate the byte contents of Crossplane packages. As such, Crossplane does not detect if an attacker has tampered with a Package. The problem has been fixed in 1.11.5, 1.12.3 and 1.13.0. As a workaround, only use images from trusted sources and keep Package editing/creating privileges to administrators only. • https://github.com/crossplane/crossplane/blob/ac8b24fe739c5d942ea885157148497f196c3dd3/security/ADA-security-audit-23.pdf • CWE-20: Improper Input Validation •

27 Jul 2023 — Crossplane is a framework for building cloud native control planes without needing to write code. In versions prior to 1.11.5, 1.12.3, and 1.13.0, a high-privileged user could create a Package referencing an arbitrarily large image containing that Crossplane would then parse, possibly resulting in exhausting all the available memory and therefore in the container being OOMKilled. The impact is limited due to the high privileges required to be able to create the Package and the eventually consistency nature ... • https://github.com/crossplane/crossplane/blob/ac8b24fe739c5d942ea885157148497f196c3dd3/security/ADA-security-audit-23.pdf • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 6.2EPSS: 0%CPEs: 3EXPL: 0CVE-2023-27484 – Unchecked fieldpath index in Composition's patches can lead to arbitrary memory allocation in crossplane
https://notcve.org/view.php?id=CVE-2023-27484
09 Mar 2023 — crossplane-runtime is a set of go libraries used to build Kubernetes controllers in Crossplane and its related stacks. In affected versions an already highly privileged user able to create or update Compositions can specify an arbitrarily high index in a patch's `ToFieldPath`, which could lead to excessive memory usage once such Composition is selected for a Composite resource. Compositions allow users to specify patches inserting elements into arrays at an arbitrary index. When a Composition is selected fo... • https://github.com/crossplane/crossplane/security/advisories/GHSA-v829-x6hh-cqfq • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
