Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Ollama < 0.1.34 fails to validate **SHA256 digest format** when fetching model paths.β¦
π₯ **Affected**: Users running **Ollama versions prior to 0.1.34**. Specifically, local deployments of the Ollama open-source LLM runner. π³ Docker users on older images are also at risk.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: With a **rogue registry server**, hackers can achieve **RCE**. They can execute arbitrary commands (e.g., reverse shells via `bash -i`) and write malicious files to the server's filesystem.β¦
π **Public Exploits**: **YES**. Multiple PoCs exist on GitHub (e.g., `Bi0x/CVE-2024-37032`, `pankass`). Automated scanners like **Nuclei** templates are also available.β¦
π **Self-Check**: 1. Check your Ollama version (`ollama --version`). 2. Use scanners like `ahboon/CVE-2024-37032-scanner` to test subnets. 3. Look for Nuclei CVE templates. π οΈ If version < 0.1.34, you are vulnerable.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed**: **YES**. Officially patched in **Ollama v0.1.34**. The fix ensures strict validation of the digest format (exactly 64 hex digits) and prevents path traversal sequences. π‘οΈ
Q9What if no patch? (Workaround)
π§ **Workaround**: If you cannot patch immediately: 1. **Isolate** Ollama from untrusted networks. 2. **Do not** pull models from unverified/rogue registries. 3. Restrict filesystem permissions for the Ollama user. π«
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. Since PoCs are public and RCE is possible, immediate upgrade to **v0.1.34+** is recommended. Do not ignore this if you expose Ollama to any external or untrusted model sources. πββοΈπ¨
