CVE-2020-6650 — UPS companion software v1.05 & Prior is affected by ‘Eval Injection’ vulnerability

High CVSS 8.8

UPS companion software v1.05 & Prior is affected by ‘Eval Injection’ vulnerability. The software does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call e.g.”eval” in “Update Manager” class when software attempts to see if there are updates available. This results in arbitrary code execution on the machine where software is installed.

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.
