Summary

A vulnerability in the authentication code of remote management via Cisco Adaptive Security Device Management (ASDM) could allow an unauthenticated, remote attacker to bypass the digital certificate authentication. Depending on the configuration, this may allow the attacker to remotely connect as administrator to the management interface via Cisco ASDM and take full control of the affected system.

The vulnerability is due to an error in the implementation of the authentication-certificate option, which enables client-side digital certificate authentication. An attacker could exploit this vulnerability by trying to authenticate to an interface of the affected system where Cisco ASDM is enabled.

What Is a Cisco Security Notice?

The Cisco Product Security Incident Response Team (PSIRT) publishes Cisco Security Notices to inform customers of low- to mid-level severity security issues involving Cisco products.

Customers who wish to upgrade to a software version that includes fixes for these issues should contact their normal support channels. Free software updates will not be provided for issues that are disclosed through a Cisco Security Notice.

For additional information about Cisco PSIRT publications, see the Cisco Security Vulnerability Policy at http://www.cisco.com/web/about/security/psirt/security_vulnerability_policy.html

Customers Using Third-Party Support Organizations

Customers may have Cisco products that are provided or maintained through prior or existing agreements with third-party support organizations, such as Cisco Partners, authorized resellers, or service providers. For these products, customers should consult their service providers or support organizations to ensure that any applied workaround or fix is the most appropriate in the intended network before it is deployed.
