CVE-2018-0329 — Cisco Wide Area Application Services security vulnerability

Medium CVSS 5.3

A vulnerability in the default configuration of the Simple Network Management Protocol (SNMP) feature of Cisco Wide Area Application Services (WAAS) Software could allow an unauthenticated, remote attacker to read data from an affected device via SNMP. The vulnerability is due to a hard-coded, read-only community string in the configuration file for the SNMP daemon. An attacker could exploit this vulnerability by using the static community string in SNMP version 2c queries to an affected device. A successful exploit could allow the attacker to read any data that is accessible via SNMP on the affected device. Note: The static credentials are defined in an internal configuration file and are not visible in the current operation configuration ('running-config') or the startup configuration ('startup-config'). Cisco Bug IDs: CSCvi40137.

Matched remediation archetype

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
