This vulnerability exists within Intelbras RX1500 version 2.2.9 and RX3000 version 1.0.11 wireless access points where insufficient input validation occurs during ESSID name processing. The flaw represents a classic injection vulnerability that allows remote attackers to manipulate the wireless network configuration by crafting malicious payloads within the Extended Service Set Identifier field. This type of vulnerability falls under CWE-94, which describes the execution of code through improper handling of externally supplied input. The vulnerability stems from inadequate sanitization of user-supplied data during the network creation process, specifically when the device processes the ESSID parameter without proper validation or encoding mechanisms.
The operational impact of this vulnerability is severe as it enables unauthenticated remote code execution on affected devices, potentially allowing attackers to gain complete control over the wireless infrastructure. An attacker can exploit this weakness by creating a malicious wireless network with a specially crafted ESSID name that contains malicious payloads designed to exploit the device's processing logic. This attack vector aligns with ATT&CK technique T1059.007 for command and scripting interpreter, as the exploitation involves injecting executable code through network configuration parameters. The vulnerability affects the device's wireless management capabilities and can lead to unauthorized network access, data interception, and potential lateral movement within the network infrastructure.
Mitigation strategies should focus on immediate firmware updates from Intelbras to address the input validation flaws in the ESSID processing logic. Network administrators should implement network segmentation and monitoring to detect anomalous wireless network creation activities. The vulnerability demonstrates the importance of input validation principles and proper sanitization of all user-supplied data, particularly in network configuration parameters. Security measures should include implementing network access controls that restrict wireless network creation privileges and monitoring for unusual ESSID patterns that may indicate exploitation attempts. Organizations should also consider deploying wireless intrusion detection systems to identify and respond to potential exploitation attempts targeting this specific vulnerability. The flaw highlights the critical need for secure coding practices and input validation testing, particularly for network infrastructure devices that handle user-supplied configuration parameters.
