CVE-2020-11920 — An issue was discovered in Svakom Siime Eye 14.1.00000001.3.330.0.0.3.14

Critical CVSS 9.8

An issue was discovered in Svakom Siime Eye 14.1.00000001.3.330.0.0.3.14. A command injection vulnerability resides in the HOST/IP section of the NFS settings menu in the webserver running on the device. By injecting Bash commands via shell metacharacters here, the device executes arbitrary code with root privileges (all of the device's services are running as root).

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.
