What is CVE-2024-0455?

CVE-2024-0455 is a critical server-side request forgery vulnerability in Mintplexlabs Anythingllm, published on 25 Feb 2024. Any signed-in user can exploit it over the network, with no action from the victim.

Official description

The inclusion of the web scraper for AnythingLLM means that any user with the proper authorization level (manager, admin, and when in single user) could put in the URL ``` http://169.254.169.254/latest/meta-data/identity-credentials/ec2/security-credentials/ec2-instance ``` which is a special IP and URL that resolves only when the request comes from within an EC2 instance. This would allow the user to see the connection/secret credentials for their specific instance and be able to manage it regardless of who deployed it.

The user would have to have pre-existing knowledge of the hosting infra which the target instance is deployed on, but if sent - would resolve if on EC2 and the proper `iptable` or firewall rule is not configured for their setup.

Weakness: CWE-918
