CVE-2010-2966 in VxWorks
Summary
by MITRE
The INCLUDE_SECURITY functionality in Wind River VxWorks 6.x, 5.x, and earlier uses the LOGIN_USER_NAME and LOGIN_USER_PASSWORD (aka LOGIN_PASSWORD) parameters to create hardcoded credentials, which makes it easier for remote attackers to obtain access via a (1) telnet, (2) rlogin, or (3) FTP session.

The vulnerability described in CVE-2010-2966 represents a critical security flaw in Wind River VxWorks operating systems versions 6.x, 5.x, and earlier releases. This issue specifically affects the INCLUDE_SECURITY functionality which is designed to manage user authentication and access control within the embedded operating system. The vulnerability stems from the improper handling of authentication credentials through hardcoded parameters that are accessible during the system initialization process. The flaw allows malicious actors to exploit the system by leveraging pre-defined login credentials that are embedded within the software configuration rather than being dynamically generated or securely stored.
The technical implementation of this vulnerability occurs through the use of LOGIN_USER_NAME and LOGIN_USER_PASSWORD parameters that are processed during the security initialization phase of VxWorks. These parameters are configured as hardcoded values that are then used to establish authentication credentials for remote access protocols including telnet, rlogin, and FTP services. The vulnerability exists because these credentials are not properly secured or randomized during system deployment, creating persistent access points that remain unchanged regardless of system updates or security policies. This design flaw fundamentally undermines the security model of the operating system by providing predictable authentication mechanisms that can be easily discovered and exploited.
The operational impact of this vulnerability is severe and multifaceted, affecting organizations that deploy VxWorks in embedded systems across various industries including automotive, aerospace, industrial control, and telecommunications. Remote attackers can exploit this vulnerability to gain unauthorized access to systems through multiple network protocols, with telnet being particularly concerning due to its plaintext transmission of credentials and commands. The rlogin and FTP protocols present additional attack vectors that could lead to complete system compromise, allowing adversaries to execute arbitrary code, modify system configurations, or extract sensitive data. This vulnerability directly violates security best practices as outlined in the CWE-798 category for hardcoded credentials and aligns with ATT&CK techniques related to credential access and remote service exploitation.
Organizations affected by this vulnerability should immediately implement comprehensive mitigation strategies including disabling unnecessary network services, implementing network segmentation to isolate affected systems, and applying available patches from Wind River if they exist. The recommended approach involves reconfiguring the system to use dynamic authentication mechanisms rather than hardcoded credentials, implementing strong access controls, and deploying network monitoring solutions to detect unauthorized access attempts. Additionally, system administrators should consider implementing network-level protections such as firewall rules that restrict access to telnet, rlogin, and FTP services, while also ensuring that any remaining services use secure protocols with proper authentication mechanisms. This vulnerability highlights the importance of proper credential management in embedded systems and demonstrates the critical need for secure configuration practices in industrial control environments where system availability and security are paramount.
