    Cisco Aironet Access Points Unauthorized Access Vulnerability


    Posted: 17 Oct 2019

    Summary

    A vulnerability in Cisco Aironet Access Points (APs) Software could allow an unauthenticated, remote attacker to gain unauthorized access to a targeted device with elevated privileges.

    The vulnerability is due to insufficient access control for certain URLs on an affected device. An attacker could exploit this vulnerability by requesting specific URLs from an affected AP. An exploit could allow the attacker to gain access to the device with elevated privileges. While the attacker would not be granted access to all possible configuration options, it could allow the attacker to view sensitive information and replace some options with values of their choosing, including wireless network configuration. It would also allow the attacker to disable the AP, creating a denial of service (DoS) condition for clients associated with the AP.

    Cisco has released software updates that address this vulnerability. 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:
    End User License Agreement - Cisco

    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 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) 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:
    Cisco Worldwide Support & Downloads Contacts - Cisco

    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.
