CVE-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 •
CVE-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 •
