CyberRota Analysis
AI-GeneratedThe execute_ruby tool is vulnerable due to inadequate restrictions on the pseudo-terminal library's spawn entry points, allowing attackers to execute arbitrary commands on the server with the same privileges as the running account. This flaw poses a significant risk, as it can lead to unauthorized access and control over the system. Organizations using versions 1.4.0 to 1.6.0 of the tool should prioritize immediate updates to version 1.6.1 or later to mitigate this high-severity vulnerability.

Original NVD Description
The execute_ruby tool is documented as a read-only Ruby sandbox and is enforced by a pattern denylist together with replacements for the process-spawning methods on Kernel. The pseudo-terminal library's spawn entry points are neither in the denylist nor replaced, so a normal tool call could reach them and start a shell, executing commands as the account running the server and outside the guarded methods. The denylist was introduced with the tool in 1.4.0 and never covered those entry points through 1.6.0. Version 1.6.1 restricts the requires the sandbox permits to a data-only list and blocks dynamic dispatch to execution entry points; 2.0.0 removes the tool.
