CWE-20

Summary

  • A vulnerability in the web-based GUI of Cisco Integrated Management Controller (IMC) could allow an unauthenticated, remote attacker to perform unauthorized remote command execution on the affected device.

    The vulnerability exists because the affected software does not sufficiently sanitize specific values that are received as part of a user-supplied HTTP request. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected software. Successful exploitation could allow an unauthenticated attacker to execute system commands with root-level privileges.

    There are no workarounds that address this vulnerability.

Fixed Software

  • Cisco has released free software updates that address the vulnerability described in this advisory. Customers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license:
    http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html

    Additionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades.

    When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories and Alerts page, to determine exposure and a complete upgrade solution.

    In all cases, customers should ensure that the devices to upgrade 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) or their contracted maintenance providers.

    Customers Without Service Contracts

    Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC:
    http://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html

    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.

    Fixed Releases

    This vulnerability is fixed in Cisco CIMC software versions 3.0.1d, 3.0.3a, and later. The Cisco CIMC software can be downloaded from the Download Software site by navigating to Products > Servers > Unified Computing > http://www.cisco.com/cisco/software/navigator.html
