A denial of service vulnerability exists in the JSONReader component of the run-llama/llama_index repository, specifically in version v0.12.37. The vulnerability is caused by uncontrolled recursion when parsing deeply nested JSON files, which can lead to Python hitting its maximum recursion depth limit. This results in high resource consumption and potential crashes of the Python process. The issue is resolved in version 0.12.38.
A path traversal vulnerability exists in run-llama/llama_index versions 0.12.27 through 0.12.40, specifically within the encode_image function in generic_utils.py. This vulnerability allows an attacker to manipulate the image_path input to read arbitrary files on the server, including sensitive system files. The issue arises due to improper validation or sanitization of the file path, enabling path traversal sequences to access files outside the intended directory. The vulnerability is fixed in version 0.12.41.
The JSONReader in run-llama/llama_index versions 0.12.28 is vulnerable to a stack overflow due to uncontrolled recursive JSON parsing. This vulnerability allows attackers to trigger a Denial of Service (DoS) by submitting deeply nested JSON structures, leading to a RecursionError and crashing applications. The root cause is the unsafe recursive traversal design and lack of depth validation, which makes the JSONReader susceptible to stack overflow when processing deeply nested JSON. This …
Incomplete Documentation of Program Execution exists in the run-llama/llama_index library's JsonPickleSerializer component, affecting versions v0.12.27 through v0.12.40. This vulnerability allows remote code execution due to an insecure fallback to Python's pickle module. JsonPickleSerializer prioritizes deserialization using pickle.loads(), which can execute arbitrary code when processing untrusted data. Attackers can exploit this by crafting malicious payloads to achieve full system compromise. The root cause involves the use of an insecure fallback strategy …
An issue was discovered in llama_index before 0.10.38. download/integration.py includes an exec call for import {cls_name}.
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 …
A vulnerability was identified in the exec_utils class of the llama_index package, specifically within the safe_eval function, allowing for prompt injection leading to arbitrary code execution. This issue arises due to insufficient validation of input, which can be exploited to bypass method restrictions and execute unauthorized code. The vulnerability is a bypass of the previously addressed CVE-2023-39662, demonstrated through a proof of concept that creates a file on the system …
