The Vulnerability: How Attackers Exploited Ollama

Drive-By Attacks via Malicious Websites

The vulnerability allowed attackers to exploit Ollama through a simple POST request. By luring users to a malicious website, attackers could:

• Remotely reconfigure local app settings without user consent.
• Access and spy on local AI chats, compromising sensitive conversations.
• Manipulate AI models by serving poisoned or malicious models to the victim’s application.

This type of attack is particularly insidious because it requires no direct interaction from the victim beyond visiting a compromised website.

Potential Consequences

The implications of this vulnerability are severe:

• Privacy violations: Unauthorized access to local chats could expose sensitive or confidential information.
• Model poisoning: Attackers could inject malicious models, leading to unpredictable or harmful AI behavior.
• System compromise: In extreme cases, attackers might gain deeper access to the victim’s system, enabling further exploitation.
