CVE-2010-3033 in Wireless LAN Controller Software
Summary
by MITRE
Cisco Wireless LAN Controller (WLC) software, possibly 4.2 through 6.0, allows remote authenticated users to bypass intended access restrictions and modify the configuration, and possibly obtain administrative privileges, via unspecified vectors, a different vulnerability than CVE-2010-2842 and CVE-2010-2843.

The vulnerability identified as CVE-2010-3033 affects Cisco Wireless LAN Controller software versions 4.2 through 6.0, representing a critical security flaw that undermines the integrity of wireless network management systems. This vulnerability specifically targets the authentication and authorization mechanisms within the WLC software, creating a pathway for remote attackers who are already authenticated to escalate their privileges and modify system configurations without proper authorization. The issue stems from insufficient access controls that fail to properly validate user permissions during administrative operations, allowing malicious actors to bypass intended security restrictions that should prevent unauthorized configuration changes.
The technical nature of this vulnerability involves improper validation of user privileges within the WLC's administrative interface, enabling authenticated users to perform operations that should be restricted to administrators only. This flaw operates at the application layer and affects the software's ability to enforce role-based access controls, creating a privilege escalation vector that can lead to complete system compromise. The vulnerability is particularly concerning because it leverages existing authenticated sessions rather than requiring initial unauthorized access, making it more difficult to detect and prevent through traditional network monitoring approaches. The unspecified vectors suggest that multiple pathways may exist within the software's permission model that can be exploited to achieve unauthorized administrative access.
The operational impact of CVE-2010-3033 extends far beyond simple configuration modifications, as successful exploitation can result in complete network compromise and unauthorized access to sensitive wireless infrastructure. Attackers who exploit this vulnerability can modify wireless network settings, potentially redirecting traffic, disabling security features, or creating backdoor access points that persist long after the initial attack. The ability to obtain administrative privileges through this vulnerability means that attackers can manipulate wireless access policies, modify user authentication settings, and potentially gain access to all wireless network resources. This represents a significant threat to enterprise wireless security, as wireless LAN controllers typically serve as central management points for large-scale wireless deployments, making them prime targets for attackers seeking persistent access to corporate networks.
Organizations affected by this vulnerability should implement immediate mitigations including applying the latest security patches from Cisco, which address the specific access control flaws in the WLC software. Network segmentation and monitoring should be enhanced to detect unusual administrative activities that may indicate exploitation attempts, while implementing additional authentication controls such as multi-factor authentication for administrative access. The vulnerability aligns with CWE-284, which describes improper access control in software systems, and represents a specific implementation of weak privilege management that allows unauthorized privilege escalation. From an ATT&CK framework perspective, this vulnerability maps to privilege escalation techniques and can be used to establish persistence within wireless network environments, potentially enabling later stages of the attack chain including lateral movement and data exfiltration through compromised wireless infrastructure.
