CVE-2020-25618 — An issue was discovered in SolarWinds N-Central 12.3.0.670

High CVSS 9

An issue was discovered in SolarWinds N-Central 12.3.0.670. The sudo configuration has incorrect access control because the nable web user account is effectively able to run arbitrary OS commands as root (i.e., the use of root privileges is not limited to specific programs listed in the sudoers file).

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.
