T1053.002 – At

1. Technical Attack Analysis:
CVE-2024-11981 describes an Authentication Bypass vulnerability affecting certain models of routers from Billion Electric. This vulnerability allows unauthenticated attackers to access and retrieve contents of arbitrary web pages hosted on the router.

Attack Techniques:
– T1053.002 – Scheduled Task/Job: Cron: This technique indicates that the attacker may exploit the router’s scheduled tasks or jobs to execute arbitrary commands or retrieve sensitive information without proper authentication.

Potential Impacts:
– Data Exposure: Attackers can gain access to sensitive information stored on the router, such as configuration files, user credentials, or network traffic logs.
– Unauthorized Access: The vulnerability could allow attackers to manipulate the router settings, leading to further exploitation of the network, such as redirecting traffic or launching subsequent attacks.
– Network Compromise: If attackers can access sensitive internal pages, they may gather intelligence to perform lateral movement within the network or even compromise additional devices.
– Denial of Service: Attackers could potentially configure the router to disrupt services, impairing network connectivity for legitimate users.

2. Mitigation Measures:
– Strengthen Security Configurations:
– Enable multi-factor authentication (MFA) for administrative access to the router.
– Restrict access permissions to the router’s web interface, allowing only specific IP addresses.
– Regularly update router firmware to the latest version provided by the vendor to patch known vulnerabilities.

– Utilize Specific Tools or Security Software:
– Deploy a reputable firewall to monitor and filter incoming and outgoing traffic to the router.
– Implement intrusion detection and prevention systems (IDPS) to identify and block suspicious activities targeting the router.
– Use endpoint protection solutions (e.g., antivirus) on devices connected to the network to help mitigate further exploitation.

– Implement Monitoring and Reporting Practices:
– Enable detailed logging on the router to capture access attempts and configuration changes.
– Set up alerts for unusual access patterns or unauthorized attempts to retrieve web pages or access the router interface.
– Regularly review logs and alerts to identify potential exploitation attempts or signs of compromise.

By taking these steps, organizations can significantly reduce the risks associated with the Authentication Bypass vulnerability in their routers and enhance their overall cybersecurity posture.
