Reviewing Recent CVEs Affecting Ollama
In the rapidly evolving landscape of software security, recent vulnerabilities have emerged that put the limelight on
Ollama, an open-source platform designed for running and managing artificial intelligence models. As it gains popularity, especially among AI developers, understanding these vulnerabilities is critical. We will explore the details of the recent Common Vulnerabilities and Exposures (CVEs) affecting Ollama, highlighting significant threats, their implications, & recommended mitigations.
Recent Vulnerabilities in Ollama
1. Critical RCE Vulnerability (CVE-2024-37032)
One of the most alarming vulnerabilities identified is known as
CVE-2024-37032, dubbed “Probllama.” According to a blog post by
Wiz, this vulnerability allows remote code execution (RCE) through path traversal flaws due to insufficient input validation.
- Severity: Critical
- Date Published: June 2024
- Impacted Version: Prior to 0.1.34
What Does This Mean?
A malicious actor could exploit this vulnerability by sending specially crafted HTTP requests to the Ollama API server, particularly the
endpoint, leading to the unintentional overwriting of files on the server. When tested, over 1,000 instances of Ollama running vulnerable versions were identified, exposing numerous AI models, including private models that typically should remain secure.
Mitigation Steps: Users are advised to immediately update their installations of Ollama to version 0.1.34 or later. Wiz researchers strongly recommend deploying the API server behind a reverse proxy that requires authentication. As noted, the default API binds to localhost, reducing risks on non-Docker installations, but the public exposure of Docker deployments suggests a significant risk.
2. DNS Rebinding Vulnerability (CVE-2024-28224)
Another major vulnerability is CVE-2024-28224, a DNS rebinding vulnerability detected in Ollama versions below 0.1.29. This loophole enables attackers to access the Ollama API remotely without proper authentication.
- Severity: High
- Date Published: April 8, 2024
Understanding DNS Rebinding
This vulnerability ultimately permits unauthorized users to chat with large language model (LLM), delete models, or induce denial-of-service (DoS) attacks. The DNS rebinding can occur in as little as three seconds after connection to a malicious web server, showcasing just how quickly this threat can materialize.
Mitigation Suggestions:
- Upgrade to Ollama 0.1.29 or higher, which incorporates fixes for this issue.
- Set up additional security measures to protect the API against unauthorized access, particularly emphasizing proper validation of host headers.
3. Additional CVEs
In addition to the aforementioned vulnerabilities, several other CVEs have been noted that may indirectly affect the efficacy and security of AI systems employing Ollama. It’s wise for developers using the platform to keep an eye out for updates regarding:
- CVE-2024-3072: Policy bypass due to improper validation in Cilium affecting Ollama setups.
- CVE-2024-3056: Cross-site scripting vulnerabilities that could be exploited in any web interface interacting with Ollama.
Impacts of These Vulnerabilities
User Impact
The exposure of these vulnerabilities poses significant risks, especially to organizations using Ollama for sensitive, proprietary, or customer-facing AI applications. There are real-world implications, including:
- Data Theft: Attackers can manipulate interactions with models, potentially leaking confidential information.
- Service Disruption: Users might encounter degraded performance or downtime due to exploitation attempts.
- Loss of Trust: If vulnerabilities are not managed properly, organizations risk losing user trust.
The development community following Ollama is concerned about the speed at which new features & tools are deployed while security implications might not have been extensively considered. Many developers are now being encouraged to adopt a more proactive approach to security testing and regular updates.
For instance, discussions on various subreddits, like
LocalLLaMA, highlight the need for better security practices when deploying AI tools in production environments.
