Architecture Risks that May Compromise AI-as-a-Service Providers

Wiz research recently performed a security audit of Hugging Face and discovered several security issues that would have allowed an actor running a specially-crafted malicious model on Hugging Face's infrastructure to achieve remote code execution and cross-tenant access to other customers' spaces or models. All these issues were remediated by Hugging Face and no customer action is required.

🐞 High Profile Vulnerabilities

DoS Vulnerability in HTTP/2 CONTINUATION Frames

HTTP allows for header and trailer fields in messages, which are serialized into blocks in HTTP/2 for fragment transmission. On April 3, 2024, several vulnerabilities were disclosed in software with HTTP/2 implementations that fail to adequately control or check the number of CONTINUATION frames within a stream. Attackers can exploit this by sending numerous CONTINUATION frames to a server, leading to memory issues or out-of-memory (OOM) crashes due to improper processing or excessive accumulation in the header list, potentially enabling denial-of-service (DoS) attacks.

Critical Vulnerability in PAN-OS Exploited in-the-Wild

CVE-2024-3400 is a command injection vulnerability in the GlobalProtect feature of PAN-OS. The vulnerability may enable an unauthenticated attacker to execute arbitrary code with root privileges on the firewall. Exploitation attempts have been observed in the wild, it is recommended to patch urgently.

According to Wiz data, 6% of cloud environments have resources vulnerable to the vulnerabilities mentioned above and exposed to the internet.

AWS Amplify Role Takeover Vulnerability

Researchers identified flaws in AWS Amplify that allowed public assumption of IAM roles associated with Amplify projects. This could occur if the authentication component was removed using the Amplify CLI or Studio between August 2019 and January 2024, or for projects created with the CLI from July 2018 to August 2019. The vulnerability, tracked as CVE-2024-28056, led AWS to promptly issue a hotfix for the CLI, enhancing IAM security and modifying its Security Token Service to prevent further exploitation by blocking cross-account role assumptions. No customer action is required.
