Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Introduction

This document describes how to use the Bug Applicability tool to scan admin-tech files for possible Indicators of Compromise (IoCs) related to SD-WAN Product Security Incident Response Team (PSIRT) CVE-2026-20182CSCwt50498

Requirements

For CSCwt50498, you must generate an admin-tech of your SD-WAN control components. The Controller (vSmart) admin-techs must be generated one at a time.

The admin-techs of other SD-WAN control components can be generated in any order.

Warning: Before upgrading an SD-WAN deployment to a fixed release, retain relevant logs. After upgrading, verify that the system has not been compromised, by checking the logs for the indicators of compromise as documented in these advisories. If the logs show indicators of compromise and you confirm that your system has been compromised, applying the software update alone will not resolve the vulnerability. In such cases, follow the specific remediation steps that are provided by the Cisco Technical Assistance Center (TAC) to help secure the system.

Admin-Tech Generation Guidelines

If you need assistance creating these files, please refer to the this document that provides the steps to generate an admin-tech: How to Collect an Admin-Tech in an SD-WAN Environment.

Limitations

  • The file size is currently limited to 500 MB.
  • Simultaneous file verification is not supported. The tool can process multiple files, but only one at a time.

Utilization

Verify an Admin-Tech

  1. Go to the Cisco Bug Search Tool page for the Cisco Bug ID you want to analyze. 
  2. Under the title, click on the text or icon "Check Bug Applicability". A pop-up window appears.
  3. Drop or select the admin-tech file you want to analyze.
