TBEA TLogger SQL Injection Allows Database Tampering

CVE advisorySeverity: CRITICAL (CVSS 9.3)

CVE-2025-13294

The vulnerability exists in the web server component of a network-connected device. As a web-based interface that handles HTTP requests and directly interacts with the device's database, it is commonly exposed as an administrative or monitoring portal accessible over the network, making it a likely target for remote access.

Horizon Alert

Summary of the vulnerability and why it matters

An unauthenticated SQL injection vulnerability exists in the web server of TBEA TLogger. This flaw allows remote attackers to access, alter, or delete data within the device's database by manipulating web requests.

Unauthenticated web server data manipulation is possible.
Impacts device data integrity and availability.
Confirm relevance and assess potential exposure.

Attack Path

How an attacker could exploit the issue

An unauthenticated attacker can leverage the TBEA TLogger web server to directly inject malicious SQL commands. By sending specially crafted HTTP requests to vulnerable endpoints, an attacker can manipulate the device's CCU.db database, potentially leading to unauthorized data access, modification, or deletion.

Unauthenticated network access required.
Triggered via HTTP requests with attacker-controlled parameters.
Allows unauthorized database access or modification.

Operational Fix

Recommended remediation, mitigation, and detection steps

This critical SQL injection vulnerability in the TBEA TLogger web server likely requires coordination between the application owners responsible for the TLogger instances and the infrastructure or network security teams who manage device access and exposure. The first practical step is to identify all TLogger devices, confirm their network reachability and business criticality, and then assign an owner for remediation planning.

Frequently asked questions

What is TBEA TLogger?

TBEA TLogger is a specialized device, often used in energy or industrial environments for monitoring and data collection. It functions as a data logger that stores operational information in a local SQLite database named CCU.db. The device includes a built-in web server to provide an interface for administrators or monitoring systems to interact with this data over the network.

What is the vulnerability in CVE-2025-13294?

This CVE describes an SQL injection vulnerability, identified by the weakness class CWE-89. It happens when software fails to properly sanitize user input before including it in a database query. In this case, the TLogger web server takes commands from web requests and inserts them directly into its internal database queries, allowing an unauthorized user to essentially 'speak' to the database and bypass standard application logic.

How is this SQL injection triggered?

An attacker triggers this flaw by sending specially crafted HTTP requests to the web server's vulnerable endpoints. The vulnerability is specifically caused by the processing of these attacker-controlled parameters. It is important to note that this does not require any specialized interaction or authenticated sessions; the flaw is reachable by anyone who can send the correct network request to the web server.

Why should I be concerned about CVE-2025-13294?

You should care if you manage TBEA TLogger devices that are accessible via a network. According to Halo Surface Signal, this vulnerability is considered a likely target because the web server is often exposed as an administrative or monitoring portal. If your device is reachable from the internet or even just a broad internal network, an unauthorized actor could potentially view, change, or erase the critical data stored in your system.

How do I respond to this threat?

Begin by creating an inventory of all TBEA TLogger devices in your environment to understand where they are deployed. Confirm which of these units are reachable over the network and determine their importance to your operations. Once you have a clear picture of your landscape, coordinate with your infrastructure and security teams to restrict network access to these interfaces while you plan further steps to address the vulnerability.
