Detailsinfo

A vulnerability was found in run-llama llama_index up to 10.25. It has been declared as very critical. This vulnerability affects the function safe_eval. The manipulation with an unknown input leads to a command injection vulnerability. The CWE definition for the vulnerability is CWE-77.

As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

A command injection vulnerability exists in the run-llama/llama_index repository, specifically within the safe_eval function. Attackers can bypass the intended security mechanism, which checks for the presence of underscores in code generated by LLM, to execute arbitrary code. This is achieved by crafting input that does not contain an underscore but still results in the execution of OS commands. The vulnerability allows for remote code execution (RCE) on the server hosting the application.
