GHSA-4H45-JPVH-6P5J

Vulnerability from github – Published: 2025-08-29 15:38 – Updated: 2025-08-29 15:38

Summary

Rancher affected by unauthenticated Denial of Service

Details

Impact

A vulnerability has been identified within Rancher Manager in which it did not enforce request body size limits on certain public (unauthenticated) and authenticated API endpoints. This allows a malicious user to exploit this by sending excessively large payloads, which are fully loaded into memory during processing. This could result in: - Denial of Service (DoS): The server process may crash or become unresponsive when memory consumption exceeds available resources. - Unauthenticated and authenticated exploitation: While the issue was initially observed in unauthenticated /v3-public/* endpoints, the absence of request body size limits also affected several authenticated APIs, broadening the potential attack surface. It's worth noting that other areas in Rancher do implement safeguards: requests proxied to Kubernetes APIs are subject to built-in size limits enforced by the Kubernetes API server itself, and Norman-based endpoints parse input with predefined size caps. However, the absence of similar protections in other Rancher APIs increased the risk of denial-of-service (DoS) scenarios in certain contexts.

By sending large binary or text payloads to vulnerable endpoints, a malicious actor could disrupt Rancher’s availability, impacting both administrative and user operations across managed clusters.

Please consult the associated MITRE ATT&CK - Technique - Network Denial of Service for further information about this category of attack.

Patches

This vulnerability is addressed by adding a default limit of 1MiB and a setting in case this value needs to be increased.

Patched versions of Rancher include releases v2.12.1, v2.11.5, v2.10.9 and v2.9.12.

Workarounds

If you can't upgrade to a fixed version, please make sure that you are manually setting the request body size limits. For example, using nginx-ingress controller and only allowing requests via the ingress. For reference on how to configure the limit manually, please consult the Knowledge Base.
