CVE-2017-14650 — Horde Horde Image Api security vulnerability

High CVSS 8.1

A Remote Code Execution vulnerability has been found in the Horde_Image library when using the "Im" backend that utilizes ImageMagick's "convert" utility. It's not exploitable through any Horde application, because the code path to the vulnerability is not used by any Horde code. Custom applications using the Horde_Image library might be affected. This vulnerability affects all versions of Horde_Image from 2.0.0 to 2.5.1, and is fixed in 2.5.2. The problem is missing input validation of the index field in _raw() during construction of an ImageMagick command line.

Matched remediation archetype

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.
