Cisco Wireless LAN Controller 4.0/5.0/6.0/7.0 Firmware/Configuration race condition

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Cisco Wireless LAN Controller 4.0/5.0/6.0/7.0 (Wireless LAN Software) and classified as critical. This issue affects some unknown functionality of the component Firmware/Configuration Handler. The manipulation with an unknown input leads to a race condition vulnerability. Using CWE to declare the problem leads to CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Cisco Wireless LAN Controller (WLC) devices 7.4 before 7.4.110.0 distribute Aironet IOS software with a race condition in the status of the administrative HTTP server, which allows remote attackers to bypass intended access restrictions by connecting to an Aironet access point on which this server had been disabled ineffectively, aka Bug ID CSCuf66202.

The weakness was disclosed 03/05/2014 with Cisco as cisco-sa-20140305-wlc as confirmed advisory (Website). The advisory is shared at tools.cisco.com. The public release has been coordinated in cooperation with Cisco. The identification of this vulnerability is CVE-2014-0703 since 01/02/2014. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are unknown but an exploit is available. The advisory points out:

The vulnerability is due to a race condition that could result in the administrative HTTP server of an affected access point being enabled even though it is explicitly disabled by an administrator. An attacker could exploit this vulnerability by attempting to authenticate to an affected device using locally-stored credentials of the AP. A successful attack could allow an attacker to take complete control of the affected AP and make arbitrary changes to the configuration. In many deployment scenarios, the locally-stored default AP username and password has not been changed from the factory default. In these zero-touch scenarios, the devices are designed to connect automatically to a WLC and download firmware and configurations.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 73018 (Multiple Vulnerabilities in Cisco Wireless LAN Controllers (cisco-sa-20140305-wlc)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CISCO. The commercial vulnerability scanner Qualys is able to test this issue with plugin 38638 (Cisco Wireless LAN Controller Multiple Vulnerabilities.).

Upgrading eliminates this vulnerability. The upgrade is hosted for download at tools.cisco.com. Applying the patch cisco-sa-20140305-wlc is able to eliminate this problem. The bugfix is ready for download at tools.cisco.com. The best possible mitigation is suggested to be upgrading to the latest version. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (91605), Tenable (73018), SecurityFocus (BID 65983†), Secunia (SA57128†) and Vulnerability Center (SBV-43487†). The entries VDB-12494, VDB-12495, VDB-12496 and VDB-12498 are pretty similar. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
