CVSS: 9.8EPSS: 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
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 https://github.com/crossplane/crossplane/security/advisories/GHSA-pj4x-2xr5-w87m • CWE-20: Improper Input Validation •
CVSS: 3.4EPSS: 0%CPEs: 2EXPL: 1CVE-2023-37900 – Crossplane vulnerable to denial of service from large image
https://notcve.org/view.php?id=CVE-2023-37900
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 of controller. This issue is fixed in versions 1.11.5, 1.12.3, and 1.13.0. • https://github.com/crossplane/crossplane/blob/ac8b24fe739c5d942ea885157148497f196c3dd3/security/ADA-security-audit-23.pdf https://github.com/crossplane/crossplane/security/advisories/GHSA-68p4-95xf-7gx8 • 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
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 for a Composite Resource, patches are evaluated and if a specified index is greater than the current size of the target slice, Crossplane will grow that slice up to the specified index, which could lead to an excessive amount of memory usage and therefore the Pod being OOM-Killed. The index is already capped to the maximum value for a uint32 (4294967295) when parsed, but that is still an unnecessarily large value. • https://github.com/crossplane/crossplane/security/advisories/GHSA-v829-x6hh-cqfq • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
