HIGH 8.3

DescriptionNVD

python-utcp is the python implementation of UTCP. Prior to 1.1.3, the _substitute_utcp_args method in cli_communication_protocol.py inserts user-controlled tool_args values directly into shell command strings without any sanitization or escaping. These commands are then executed via /bin/bash -c (Unix) or powershell.exe -Command (Windows), allowing an attacker to inject arbitrary shell commands. This vulnerability is fixed in 1.1.3.

AnalysisAI

Command injection in python-utcp allows remote attackers to execute arbitrary shell commands on Unix and Windows systems when user-controlled tool arguments are processed by the CLI communication protocol module. The _substitute_utcp_args method in cli_communication_protocol.py directly embeds unsanitized user input into bash or PowerShell commands without escaping, enabling full remote code execution. …

RemediationAI

Within 24 hours: Identify all systems and applications using python-utcp and document current versions in use. Within 7 days: Upgrade python-utcp to version 1.1.2 or later across all affected systems; prioritize production and internet-facing deployments. …
