This vulnerability resides in wireless network infrastructure components that process beacon frames, specifically within the handling of information element headers. The issue manifests when the system encounters beacon frames containing information elements with malformed or invalid header length fields, leading to a temporary denial of service condition. The vulnerability stems from insufficient validation mechanisms within the wireless access point or controller software that processes these frames without proper bounds checking or error handling for malformed IE structures. According to CWE-129, this represents an insufficient validation of length fields, which allows attackers to craft malicious beacon frames that trigger buffer overflows or memory corruption conditions during frame parsing.
The technical exploitation occurs when wireless devices receive beacon frames where the information element header length field contains values that exceed expected ranges or are set to zero, causing the receiving system to attempt processing malformed data structures. This condition typically results in system instability, requiring manual intervention or automatic restart to restore normal operation. The operational impact affects wireless network availability and performance, potentially disrupting connectivity for all devices within range of the affected access point. Attackers can leverage this vulnerability by broadcasting specially crafted beacon frames that cause the target device to crash or enter a non-responsive state, effectively creating a transient denial of service condition.
Network administrators should implement immediate mitigations including firmware updates from vendors, deployment of wireless intrusion detection systems that can identify and block malformed beacon frames, and configuration of access points to limit beacon frame processing or implement additional validation layers. The ATT&CK framework categorizes this under T1498.001 for Denial of Service by Resource Exhaustion, where the vulnerability exploits a resource processing flaw to consume system resources and cause temporary service disruption. Organizations should also consider network segmentation to limit the impact scope, implement monitoring for unusual beacon frame patterns, and establish incident response procedures for wireless network availability issues. The vulnerability highlights the importance of robust input validation in wireless protocol implementations and demonstrates how seemingly minor parsing flaws can result in significant operational disruptions.
