RunAdHocCommand Command Injection via Limit Parameter

Publication date: 2026-09-23

Last updated on: 2026-09-23

Assigner: redhat-SADP

Description
RunAdHocCommand.build_args() appends limit as bare positional (args.append(limit)) instead of using args.extend(['-l', limit]) like RunJob. A limit beginning with - is parsed as an ansible CLI option. Currently limited to short-circuit flags (--version, --help) since injected element displaces required pattern positional. Would escalate if ansible-core ever defaults pattern.

Executive Summary

This vulnerability involves the RunAdHocCommand.build_args() function incorrectly appending the limit parameter as a bare positional argument instead of using the proper CLI syntax with -l flag. This allows a limit value starting with - to be misinterpreted as an Ansible CLI option, potentially leading to unintended command behavior.

Detection Guidance

This vulnerability involves improper handling of the 'limit' parameter in ansible commands, which could allow command injection if not properly sanitized. Detection requires reviewing ansible command usage in scripts or automation tools for instances where 'limit' is passed as a bare positional argument without proper flag handling.

Impact Analysis

An attacker with limited privileges could exploit this to manipulate command execution by injecting options that bypass intended restrictions. This could lead to unauthorized actions or information disclosure, though current impact is limited due to required conditions.

Mitigation Strategies

Immediately review and update any scripts or automation tools using ansible commands to ensure the 'limit' parameter is passed using the '-l' flag (e.g., ansible -l <limit> <hosts>). Avoid passing 'limit' as a bare positional argument. Monitor ansible-core updates for changes that may expose this issue further.
