The vulnerability identified as CVE-2018-18377 affects Orange AirBox Y858_FL_01.16_04 devices, representing a critical security flaw in the firmware implementation of these networking appliances. This issue resides within the goform/setReset function which provides an unauthenticated interface for resetting the router to its factory default configuration. The vulnerability stems from inadequate access controls and authentication mechanisms within the device's web management interface, allowing any remote attacker to exploit this functionality without requiring valid credentials or administrative privileges.
The technical implementation of this flaw demonstrates a classic lack of input validation and authorization checks within the device's web server component. When an attacker accesses the goform/setReset endpoint, the system processes the reset request without verifying the requester's credentials or authorization level. This function operates with elevated privileges by design but fails to enforce proper authentication boundaries, creating an attack vector that directly compromises the device's security posture. The vulnerability is classified under CWE-287 which addresses improper authentication issues, specifically the lack of proper access control mechanisms in network devices.
The operational impact of this vulnerability is severe and multifaceted, as it effectively neutralizes the device's security configuration and restores default credentials that are widely known and documented. Once exploited, attackers gain complete administrative control over the router, enabling them to modify network settings, implement man-in-the-middle attacks, monitor network traffic, and potentially establish persistent access points within the network infrastructure. The default admin:admin credential combination provides attackers with immediate administrative access, eliminating the need for additional reconnaissance or credential cracking efforts. This vulnerability particularly affects enterprise and home network environments where these devices are commonly deployed, potentially exposing sensitive network information and creating entry points for further lateral movement.
Network security frameworks such as MITRE ATT&CK recognize this type of vulnerability under techniques involving privilege escalation and credential access. The exploitation of this vulnerability aligns with ATT&CK technique T1078 which covers valid accounts and T1068 which addresses exploit for privilege escalation. Organizations utilizing these devices face significant risk of unauthorized network access and potential data breaches, as the default configuration provides minimal security protection. The vulnerability also violates security best practices outlined in NIST SP 800-44 and ISO/IEC 27001 standards, which require proper access control mechanisms and authentication for all administrative functions. The lack of secure default configurations and insufficient input validation creates a persistent security risk that requires immediate remediation through firmware updates or network segmentation measures to prevent unauthorized access and maintain network integrity.
