Authenticated SQL injection in Cisco Secure FMC web-based management interface

IdentifiersCVE-2026-20002CWE-89· Improper Neutralization of Special…

CVE-2026-20002 is an SQL injection vulnerability in the web-based management interface of Cisco Secure FMC Software. The issue is caused by inadequate validation of user-supplied input, allowing an authenticated remote attacker to send crafted requests to an affected device and inject SQL. Successful exploitation can provide full access to the underlying database and enable reading certain files from the underlying operating system.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

An authenticated remote attacker can achieve high-impact compromise of confidentiality and integrity by obtaining full access to the Cisco Secure FMC database and reading certain files on the underlying operating system. The provided CVSS v3.1 vector is AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N (no availability impact indicated).

Mitigation

If you can’t patch tonight, do this now.

No specific mitigations are provided in the supplied content beyond applying Cisco’s advisory-referenced update. As exploitation requires authentication, reducing exposure of the FMC management interface and limiting/monitoring access to authenticated accounts may reduce risk, but definitive mitigations are not available from the provided material.

Remediation

Patch, then assume compromise.

Apply the Cisco-provided fix for CVE-2026-20002 as referenced in Cisco Security Advisory cisco-sa-fmc-sql-injection-2qH6CcJd (https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-fmc-sql-injection-2qH6CcJd).
