CVE-2023-37900
LowCVSS 3.4Exploitation Probability (EPSS)
Low risk40th percentile — higher than 40% of all known CVEs
Summary
In versions prior to 1.11.5, 1.12.3, and 1.13.0, Crossplane allows high-privileged users to create Packages referencing arbitrarily large images. This could lead to exhausting available memory and result in the container being OOMKilled.
Risk Assessment
The risk to the organization is the potential for memory resource exhaustion by high-privileged users, which could lead to service outages.
Recommendation
It is recommended to upgrade to versions 1.11.5, 1.12.3, or 1.13.0 to mitigate this vulnerability.
Original NVD description (English source)
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.
