Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Github.com/sipeed/picoclaw, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

picoclaw <=v0.1.2 and earlier is vulnerable to OS command injection via the ExecTool component (pkg/tools/shell.go). The guardCommand() function attempts to restrict shell command execution using a denylist of 8 regular expressions, but the denylist is incomplete.
