CVE-2017-14500 — Newsbeuter Newsbeuter security vulnerability

High CVSS 8.8

Improper Neutralization of Special Elements used in an OS Command in the podcast playback function of Podbeuter in Newsbeuter 0.3 through 2.9 allows remote attackers to perform user-assisted code execution by crafting an RSS item with a media enclosure (i.e., a podcast file) that includes shell metacharacters in its filename, related to pb_controller.cpp and queueloader.cpp, a different vulnerability than CVE-2017-12904.

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.
