User InteractionNone needed
Summary

Airspan Networks Mimosa devices and management platform contain multiple critical vulnerabilities (CWE-285 authorization bypass, CWE-863 improper access control, CWE-918 unsanitized HTTP request, CWE-89 SQL injection, CWE-502 deserialization of untrusted data, CWE-78 OS command injection, CWE-327 weak cryptography) that allow unauthenticated remote attackers to execute arbitrary code on devices and compromise connected AWS infrastructure. Successful exploitation could result in unauthorized access to customer data, organization details, and compromise of EC2 instances and S3 buckets containing sensitive information.

What this means
What could happen
An attacker could remotely execute code on Mimosa wireless access point devices and the associated AWS cloud infrastructure, gaining access to customer data, organization details, and potentially disrupting network connectivity across your wireless backhaul or access network.
Who's at risk
This affects organizations using Airspan Networks Mimosa wireless point-to-multipoint (PTMP) and point-to-point (PTP) access points, and Mimosa Management Platform (MMP) for network backhaul or last-mile access delivery. This includes wireless ISPs, municipal networks, and utility broadband deployments that rely on these devices for data transport.
How it could be exploited
An attacker could send specially crafted requests over the network to the Mimosa device's management interface, exploiting authentication bypass and injection vulnerabilities to execute arbitrary code on the device and connect to the AWS cloud backend, compromising EC2 instances and S3 storage buckets.
Prerequisites
  • Network access to the Mimosa device management interface (typically port 80/443)
  • Device must be cloud-connected to AWS
  • No authentication required for initial exploit
