Horizon Alert

Summary of the vulnerability and why it matters

A vulnerability in Faydam Datalogger could allow an attacker to execute unauthorized commands, potentially impacting data integrity and system availability.

Allows unauthorized database commands.
Potentially affects critical data systems.
Confirm relevance and exposure.

Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by sending specially crafted SQL commands over the network to the FAYDAM Datalogger. This could allow them to manipulate the database, potentially leading to unauthorized access to sensitive information or even complete control over the system.

Entry condition: Unauthenticated network access to the datalogger.
Trigger point: Sending malicious SQL commands.
Resulting risk: Complete system compromise and data exfiltration.

Live Threat

Current exploitation, exposure, and threat context

A SQL injection vulnerability in FAYDAM Datalogger could allow an unauthenticated attacker to execute arbitrary SQL commands. This could potentially lead to unauthorized access, modification, or deletion of data stored within the logger's database.

Database integrity and confidentiality at risk.
Network-accessible interface vulnerable to injection.
Unauthorized data access or manipulation.

Operational Fix

Recommended remediation, mitigation, and detection steps

The Faydam Innovation Inc. FAYDAM Datalogger is susceptible to SQL injection due to improper neutralization of special elements. This critical vulnerability, affecting versions prior to 2.8.0, allows unauthenticated attackers to execute arbitrary SQL commands by exploiting network-accessible interfaces. Identifying all instances of the FAYDAM Datalogger, confirming their network exposure and business criticality, and then engaging the appropriate application or infrastructure owners are the crucial first steps. Subsequent remediation planning should be risk-based, considering factors like vendor coordination and scheduled maintenance windows.

Identify asset owners and their deployments.
Verify network exposure and criticality.
Plan phased remediation based on risk.

Frequently asked questions

What is FAYDAM Datalogger and how is it used?

FAYDAM Datalogger is software developed by Faydam Innovation Inc. designed to facilitate remote data collection and reporting. It acts as a gateway or interface that aggregates information from various sources, helping organizations monitor and manage their data streams efficiently.

What does SQL injection mean for CVE-2026-16019?

This CVE involves a weakness classified as CWE-89, or Improper Neutralization of Special Elements used in an SQL Command. In plain English, the software fails to properly filter user-supplied input before processing it as a database command. An attacker can manipulate this input to trick the system into running unauthorized queries, effectively letting them interact with the underlying database without permission.

How can an attacker trigger this vulnerability?

An attacker triggers this bug by sending specially crafted SQL commands to the datalogger over a network. The vulnerability requires unauthenticated network access, meaning the attacker does not need a user account to send these malicious requests. Simply interacting with the application interface normally or using non-malicious input will not trigger the vulnerability; it specifically requires input designed to exploit the SQL processing logic.

Do I need to worry if my FAYDAM Datalogger is internal?

Halo Surface Signal indicates that these devices are often used as gateways, making public-internet exposure of their management interfaces a common deployment scenario. If your instance is truly isolated from the internet on an internal network, the risk is lower; however, you should still confirm whether any internal users or compromised devices could reach the interface, as the threat originates from network-based access.

How should I respond to this FAYDAM Datalogger advisory?

Your first step is to perform an inventory to locate all running instances of the FAYDAM Datalogger within your environment. Once identified, verify their specific versions, as this vulnerability affects versions 2.7.1 through 2.7.x before 2.8.0. Coordinate with your infrastructure and application owners to assess the criticality of these assets, verify their network accessibility, and plan for an update to a patched version.
