CVE-2026-87688: CWE-77: Command Injection in Brocade Fabric OS
Description
CVE-2026-87688 is a command injection vulnerability in the Brocade Fabric OS administrative management API's security certificate management component. It arises from insufficient input sanitization of user-supplied certificate identifiers during certificate management operations. An authenticated attacker with privileges to delete certificates can exploit this flaw to execute arbitrary system commands with the management daemon's privileges. This affects Fabric OS versions before 9.2.2d and versions 10.0.0 through 10.0.0a1.

Technical Analysis
This vulnerability involves improper input validation in the certificate management API of Brocade Fabric OS. Specifically, user-supplied certificate identifiers are not adequately sanitized before being passed to external system routines, enabling command injection. An attacker with authenticated access and certificate deletion privileges can leverage this to execute arbitrary commands with elevated privileges. The affected versions are Fabric OS versions prior to 9.2.2d and from 10.0.0 up to and including 10.0.0a1.
Potential Impact
Successful exploitation allows an authenticated user with certificate deletion privileges to execute arbitrary system commands with the privileges of the management daemon, potentially leading to full system compromise or unauthorized control over the device's management functions.
Mitigation Recommendations
No explicit patch or remediation information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict certificate deletion privileges to trusted administrators only and monitor for suspicious activity related to certificate management operations.
