Anevia Flamingo Weak Default Credentials Enable Remote System Control

CVE advisorySeverity: CRITICAL (CVSS 9.3)

CVE-2023-53983

The affected product is an appliance platform used for video distribution and streaming. Such appliances are commonly deployed as network edge or gateway devices to manage video services, making their administrative interfaces and management services frequently exposed or reachable within the environments where they are deployed.

Horizon Alert

Summary of the vulnerability and why it matters

A critical vulnerability has been identified in Anevia Flamingo devices, stemming from weak default administrative credentials. This allows unauthorized access, potentially leading to full remote system control without requiring sophisticated exploitation methods. The main concern is confirming if our deployed systems are affected and assessing any potential exposure.

Weak default passwords grant easy system access.
This could allow unauthorized remote control.
Confirm relevance and exposure for our systems.

Attack Path

How an attacker could exploit the issue

An attacker can reach the vulnerable component over the network by guessing weak, default administrative credentials. This allows them to gain full remote system control.

Entry condition: Network access.
Trigger point: Guessing default credentials.
Resulting risk: Full remote system control.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could allow an attacker to gain full remote control of the affected system. This is possible due to weak, easily guessable default administrative credentials that do not require complex authentication.

System control is at risk.
Unauthenticated remote access could occur.
Full system compromise is possible.

Operational Fix

Recommended remediation, mitigation, and detection steps

This vulnerability, stemming from weak default administrative credentials, likely impacts infrastructure and platform teams responsible for the Anevia Flamingo devices. The critical first step is to locate all instances of the affected technology within your environment, determine their network exposure and business criticality, and identify the accountable owner for each. Subsequently, remediation efforts should be planned based on the assessed risk.

Infrastructure or Platform teams should own the issue.
Verify device reachability and business criticality first.
Plan remediation or risk reduction based on exposure.

Frequently asked questions

What is the Anevia Flamingo XL/XS?

The Anevia Flamingo series, now part of Ateme, comprises appliance platforms designed for video distribution and streaming services. These devices act as specialized hardware gateways that manage media workflows and service delivery. They are often deployed as critical infrastructure in professional environments to handle video traffic and system management.

What does CVE-2023-53983 mean for my security?

This vulnerability is classified under CWE-798, which refers to the use of hard-coded credentials. In this specific case, it means the administrative account comes pre-configured with a default password that is easily guessable. Because these credentials are built into the system, an attacker who knows them can bypass authentication to gain full remote control of the device.

How does an attacker trigger this vulnerability?

An attacker triggers this bug simply by providing the hard-coded default administrative credentials over a network connection to the device. No complex exploitation, software bugs, or memory corruption techniques are required to gain access. If the system is configured to use secure, custom passwords, the default credential path is effectively negated.

Is my device at risk based on Halo Surface Signal?

Halo Surface Signal indicates a 'Likely' risk because Anevia Flamingo appliances often serve as network edge or gateway devices. These roles frequently require the management interface to be reachable over the network, increasing the chance that an attacker could attempt to access the system remotely if it is connected to a reachable network segment.

How should I respond if I use this technology?

Your first step is to perform an inventory of all Flamingo devices in your environment to identify where they are deployed. Determine which devices are reachable over your network and assess their business criticality. Once mapped, assign an owner to each device to oversee the necessary updates or security hardening steps to replace default credentials.
