The Action Orchestrator feature contains a Path Traversal vulnerability that allows an attacker (or compromised agent) to write to arbitrary files outside of the configured workspace directory. By supplying relative path segments (../) in the target path, malicious actions can overwrite sensitive system files or drop executable payloads on the host.
Details
Location: src/praisonai/praisonai/cli/features/action_orchestrator.py (Lines 402, 409, 423)
Vulnerable Code snippet:
target = workspace / step.target
In the _apply_step method, paths are constructed by concatenating the workspace path with a user-supplied step.target string: target = workspace / step.target. The code fails to resolve and validate that the final absolute path remains within the bounds of the workspace directory. When processing FILE_CREATE or FILE_EDIT actions, this flaw permits arbitrary file modification.
PoC
Construct a malicious ActionStep payload with path traversal characters:
from praisonai.cli.features.action_orchestrator import ActionStep, ActionType, ActionStatus
# Payload targeting a file outside the workspace
step = ActionStep(
id="test_traversal",
action_type=ActionType.FILE_CREATE,
description="Malicious file write",
target="../../../../../../../tmp/orchestrator_pwned.txt",
params={"content": "pwned"},
status=ActionStatus.APPROVED
)
# When the orchestrator applies this step, it writes to the traversed path
# _apply_step(step)
Impact
This is an Arbitrary File Write vulnerability. Anyone running the Action Orchestrator to apply modifications is vulnerable. A malicious prompt could trick the agent into generating a plan that overwrites critical files (e.g., ~/.ssh/authorized_keys, .bashrc) leading to Remote Code Execution (RCE) or system corruption.
The vulnerability requires local access to the device to be exploited. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Exploitation activity has been observed. Apply available patches or mitigations urgently.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
