Description

Summary

OpenClaw Windows Scheduled Task script generation allowed unsafe argument handling in generated gateway.cmd files. In vulnerable versions, cmd metacharacter-only values could be emitted without safe quoting/escaping, which could lead to unintended command execution when the scheduled task runs.

Details

The issue affected Windows daemon startup script generation in src/daemon/schtasks.ts.

Vulnerable behavior included:

  • Incomplete cmd argument quoting for metacharacter-only values.
  • Incomplete handling of cmd expansion-sensitive characters in script arguments.
  • Missing CR/LF guards for script-rendered fields.

The fix hardens Windows script generation by:

  • Separating schtasks argument quoting from batch script argument quoting.
  • Quoting cmd metacharacter arguments and escaping % / ! expansion cases.
  • Rejecting CR/LF in command arguments, task descriptions, and rendered environment assignments.
  • Adding regression tests for metacharacter and line-break injection paths.

Impact

This issue is local to Windows deployments and requires control over values that feed service script generation (for example install-time/runtime arguments or environment-derived values). It can result in unintended command execution in the scheduled task context.
