CVE-2020-3378: Cisco SD-WAN vManage Software SQL Injection Vulnerability

A vulnerability in the web-based management interface for Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to impact the integrity of an affected system by executing arbitrary SQL queries. The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending crafted input that includes SQL statements to an affected system. A successful exploit could allow the attacker to modify entries in some database tables, affecting the integrity of the data.

Security readout for executives and security teams

Plain-English summary

Cisco SD-WAN vManage had an authenticated SQL injection issue in its web management interface. A logged-in remote attacker could send crafted input that causes unauthorized database queries, potentially changing some database records and undermining management data integrity.

Executive priority

Treat as a moderate management-plane integrity risk. Prioritize remediation where vManage is internet-reachable, broadly accessible, or used by many privileged operators.

Technical view

CVE-2020-3378 is CWE-89 SQL injection in Cisco SD-WAN vManage Software. The issue stems from insufficient validation of user-supplied input in the web-based management interface. The CVSS v3.0 score is 4.3, with network access, low complexity, low privileges, and no user interaction required.

Likely exposure

Exposure is most relevant where Cisco SD-WAN vManage is deployed and authenticated users can reach the web management interface. The source bundle does not identify affected version ranges.

Exploitation context

The CVE is not marked as CISA KEV in the provided data. The sources describe authenticated remote exploitation but provide no evidence of active exploitation or public weaponization.

Researcher notes

Evidence supports authenticated SQL injection affecting database integrity. The provided CVSS vector lists confidentiality impact, while the description emphasizes data modification; rely on Cisco advisory details for exact impact and fixes.

Mitigation direction

  • Review Cisco advisory for affected and fixed vManage releases.
  • Upgrade or patch according to Cisco guidance.
  • Restrict vManage web interface to trusted management networks.
  • Limit vManage accounts to necessary privileges only.
  • Monitor for unexpected configuration or database-backed changes.

Validation and detection

  • Inventory Cisco SD-WAN vManage deployments and versions.
  • Confirm whether the web management interface is reachable remotely.
  • Check Cisco advisory applicability against deployed releases.
  • Review vManage user accounts for unnecessary access.
  • Inspect logs for unusual authenticated management activity.
