Researchers discovered a serious security vulnerability in the Replicate AI platform that compromised AI models. Since the vendors patched the flaw after the bug report, the threat no longer persists, but still shows the severity of any vulnerabilities affecting the AI models.
Replicating AI vulnerability demonstrates the risk to AI models
According to a recent after from cloud security company Wiz, their researchers discovered a serious security vulnerability with Replicate AI.
Replicate AI is an AI-as-a-service provider that enables users to run machine learning models at scale in clouds. It provides computing resources to run open-source AI models, giving AI enthusiasts more personalization and technical freedom to experiment with AI as they wish.
On the vulnerability side, Wiz’s post elaborates on the flaw in the Replicate AI platform that could cause an adversary to threaten other AI models. The issue arose specifically because of how an adversary could create and upload malicious Cog containers to the platform and then interact with them through Replicate AI’s interface to achieve remote code execution. After obtaining RCE, the researchers, demonstrating an attacker’s approach, achieved lateral movement on the infrastructure.
In short, they could abuse their root RCE privileges to examine the contents of an established TCP connection associated with a Redis instance within the Kubernetes cluster hosted on the Google Cloud Platform.
Because these Redis instances serve multiple customers, the researchers found that they could conduct a cross-tenant data access attack and interfere with the responses that other customers should receive by injecting arbitrary data packets. This would help them bypass the Redis authentication requirement, and they could inject rogue tasks to negatively impact other AI models.
Regarding the impact of this vulnerability, the researchers stated:
An attacker could have queried customers’ private AI models, potentially exposing proprietary knowledge or sensitive data involved in the model training process. In addition, interception of leads may have exposed sensitive data, including personally identifiable information (PII).
Replicate AI-deployed solutions
Following this discovery, the researchers responsibly disclosed the issue to Replicate AI, who fixed the flaw. According to them afterReplicate AI has deployed full mitigation, further strengthening security with additional mitigations. Nevertheless, they assured that they had not detected any attempts to exploit this vulnerability.
Moreover, they also announced to apply encryption to all internal traffic and restrict privileged network access for all model containers.
