CVE-2021-1362 — Cisco Prime License Manager security vulnerability

High CVSS 9

A vulnerability in the SOAP API endpoint of Cisco Unified Communications Manager, Cisco Unified Communications Manager Session Management Edition, Cisco Unified Communications Manager IM & Presence Service, Cisco Unity Connection, and Cisco Prime License Manager could allow an authenticated, remote attacker to execute arbitrary code on an affected device. This vulnerability is due to improper sanitization of user-supplied input. An attacker could exploit this vulnerability by sending a SOAP API request with crafted parameters to an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges on the underlying Linux operating system of the affected device.

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.
