Cisco Crosswork SQL Injection Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 10.0)

CVE-2026-20030

Cisco Crosswork is an orchestration and management platform for network infrastructure. While it is typically deployed within internal network management segments, it may be reachable in some network environments. Public internet exposure is not the standard design for this product class, but it is plausibly accessible depending on the specific deployment and configuration.

Horizon Alert

Summary of the vulnerability and why it matters

This advisory concerns vulnerabilities discovered internally within Cisco Crosswork software, related to how it handles SQL commands. The primary concern at this time is to confirm if this specific software is deployed within your environment, as the potential impact is significant if it is.

SQL command flaws in network management software.
Confirming exposure is the key leadership action.
Understand potential impact; confirm relevance internally.

Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by sending specially crafted SQL commands over the network. This could happen if the affected component is exposed externally, even without any user interaction or prior privileges. Successfully exploiting this could allow an attacker to gain high levels of control over the system.

Entry: Network access.
Trigger: Sending malicious SQL commands.
Risk: Complete system compromise and data manipulation.

Live Threat

Current exploitation, exposure, and threat context

Improper handling of SQL commands could allow an attacker to execute arbitrary SQL queries against the system. This could potentially lead to unauthorized access to, modification of, or deletion of data.

System database integrity.
Malicious SQL commands sent.
Unauthorized data access or modification.

Operational Fix

Recommended remediation, mitigation, and detection steps

Real-world action for this vulnerability likely falls to the Cisco Crosswork platform owners and the network infrastructure teams responsible for its deployment and security. The immediate first step should be to inventory all instances of the affected Cisco Crosswork software, confirm their network exposure, and identify the business-criticality and accountable owners. Remediation efforts should then be prioritized based on this risk assessment, potentially involving coordination with Cisco for the software hardening release.

Platform and infrastructure teams own remediation.
Verify network exposure and business criticality.
Plan targeted updates based on risk.

Frequently asked questions

What is Cisco Crosswork?

Cisco Crosswork is an orchestration and management platform designed to help organizations manage, automate, and optimize their complex network infrastructure. It acts as a central hub for controlling various network functions and maintaining system-wide visibility.

What does CVE-2026-20030 mean by SQL injection?

This CVE involves a weakness classified as CWE-89, which refers to the improper neutralization of special elements in SQL commands. In simple terms, the software fails to properly filter input, allowing an attacker to inject and execute their own unauthorized database commands.

How can an attacker trigger this vulnerability?

An attacker triggers this flaw by sending specially crafted SQL commands over the network to the affected system. The vulnerability does not require prior user privileges or specific user interaction; however, it does require network-level access to the vulnerable component.

Is my instance of Cisco Crosswork at risk?

According to Halo Surface Signal, Cisco Crosswork is typically deployed in internal network management segments and is not designed for public internet exposure. However, it may be reachable depending on your specific network environment and configuration, which dictates your level of risk.

What should I do first to address this?

Start by creating an inventory of all Cisco Crosswork instances in your environment. Once you have identified them, verify their network exposure and business criticality, then coordinate with your network infrastructure teams to plan updates using the hardening release provided by Cisco.
