Ollama Possible RCE via Model Loading

Splunk Security Content

View Source
Summary
This detection rule targets potential remote code execution (RCE) vulnerabilities associated with the Ollama server's model loading processes. It monitors for error conditions that arise during model loading, which may indicate attempts to exploit the server through malicious model injections or path traversal attacks. The rule employs a combination of error message searches that are typical of RCE attempts, such as indications of service crashes or abnormal model-related errors. When errors matching specified patterns are detected, the rule aggregates relevant information, including the type of errors, their frequency, and timestamps to assess severity and potential impact. This helps in identifying anomalous behaviors that could suggest malicious exploitation of the Ollama model loading features.
