Summary

Cisco UCS Manager Software Command Injection Vulnerability

Notes

Summary

A vulnerability in the CLI and web-based management interface of Cisco UCS Manager Software could allow an authenticated, remote attacker with valid administrative privileges to execute arbitrary commands on the underlying operating system of an affected device. This vulnerability is due to insufficient input validation of command arguments that are supplied by the user. An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input to the affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system of an affected device with root-level privileges. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. This advisory is part of the February 2026 Cisco FXOS and NX-OS Software Security Advisory Bundled Publication. For a complete list of the advisories and links to them, see Cisco Event Response: February 2026 Semiannual Cisco FXOS and NX-OS Software Security Advisory Bundled Publication ["https://sec.cloudapps.cisco.com/security/center/viewErp.x?alertId=ERP-75740"].

Vulnerable Products

At the time of publication, this vulnerability affected the following Cisco products if they were running a vulnerable release of Cisco UCS Manager Software, regardless of device configuration: UCS 6300 Series Fabric Interconnects UCS 6400 Series Fabric Interconnects UCS 6500 Series Fabric Interconnects UCS 6600 Series Fabric Interconnects UCS X-Series Direct Fabric Interconnects 9108 100G For information about which Cisco software releases were vulnerable at the time of publication, see the Fixed Software ["#fs"] section of this advisory. See the Details section in the bug ID at the top of this advisory for the most complete and current information.

Cisco has confirmed that this vulnerability does not affect the following Cisco products: Firepower 1000 Series Firepower 2100 Series Firepower 4100 Series Firepower 9300 Security Appliances MDS 9000 Series Multilayer Switches Nexus 3000 Series Switches Nexus 5500 Platform Switches Nexus 5600 Platform Switches Nexus 6000 Series Switches Nexus 7000 Series Switches Nexus 9000 Series Fabric Switches in ACI mode Nexus 9000 Series Switches in standalone NX-OS mode Secure Firewall 200 Series Secure Firewall 1200 Series Secure Firewall 3100 Series Secure Firewall 4200 Series Secure Firewall 6100 Series

Workarounds

There are no workarounds that address this vulnerability.

Fixed Software

Cisco considers any workarounds and mitigations (if applicable) to be temporary solutions until an upgrade to a fixed software release is available. To fully remediate this vulnerability and avoid future exposure as described in this advisory, Cisco strongly recommends that customers upgrade to the fixed software indicated in this advisory. Cisco UCS Software At the time of publication, the release information in the following table was accurate. See the Details section in the bug ID at the top of this advisory for the most complete and current information. The left column lists Cisco software releases, and the right column indicates whether a release was affected by the vulnerability described in this advisory and which release included the fix for this vulnerability. UCS 6300 Series, 6400 Series, 6500 Series, 6600 Series, and 9108 100G Fabric Interconnects Cisco UCS Software Release First Fixed Release 4.1 and earlier Migrate to a fixed release. 4.2 Migrate to a fixed release. 4.3 4.3(6f) 6.0 6.0(2) (Mar 2026) To determine the best release for Cisco UCS Software, see the Recommended Releases documents in the release notes for the device. The Cisco Product Security Incident Response Team (PSIRT) validates only the affected and fixed release information that is documented in this advisory.

Customers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade. When considering software upgrades ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"], customers are advised to regularly consult the advisories ["https://www.cisco.com/go/psirt"] for the relevant Cisco products to determine exposure and a complete upgrade solution. In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) ["https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html"] or their contracted maintenance providers.
