CVE-2017-1000393 — Jenkins Jenkins security vulnerability

High CVSS 9

Jenkins 2.73.1 and earlier, 2.83 and earlier users with permission to create or configure agents in Jenkins could configure a launch method called 'Launch agent via execution of command on master'. This allowed them to run arbitrary shell commands on the master node whenever the agent was supposed to be launched. Configuration of this launch method now requires the Run Scripts permission typically only granted to administrators.

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
