TeknoPass Authorization Bypass SQL Injection Vulnerability.

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-4104

TeknoPass is an automation and management platform typically deployed as a web-based service. Such systems are commonly configured as internet-facing portals to allow remote access for administration or user interactions, making them reachable from the public internet in typical deployment scenarios.

Horizon Alert

Summary of the vulnerability and why it matters

This advisory details a critical vulnerability in Akmer Informatics' TeknoPass system that could allow unauthorized access to sensitive data and system control. The issue is an authorization bypass, enabling SQL injection, which presents a significant risk if the affected system is exposed. The main concern is confirming relevance and exposure for the business.

Unauthorized system access is possible.
Critical system vulnerability for automation.
Confirm relevance and exposure to TeknoPass.

Attack Path

How an attacker could exploit the issue

An attacker could bypass authorization controls in the TeknoPass system by exploiting a vulnerability that allows SQL injection. This could occur if the attacker can manipulate a user-controlled primary key input. Successful exploitation could lead to attackers gaining administrative control or accessing sensitive information within the system.

Network access is required.
User-controlled primary key input is manipulated.
Unauthorized access and data compromise.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could allow an unauthenticated attacker to bypass authorization controls and inject malicious SQL code into the TeknoPass system. When supported by the advisory, this could lead to unauthorized access to and manipulation of sensitive system and user data.

System and user data may be exposed.
Malicious SQL code can be injected remotely.
Unauthorized access and data alteration are possible.

Operational Fix

Recommended remediation, mitigation, and detection steps

System owners and platform teams are likely responsible for addressing this SQL injection vulnerability in TeknoPass. The first practical step is to identify all instances of TeknoPass within the environment, assess their exposure and business criticality, and then confirm the accountable owner for each instance to plan appropriate remediation actions.

Identify TeknoPass asset ownership.
Verify external reachability and criticality.
Plan remediation based on exposure.

Frequently asked questions

What is the TeknoPass system?

TeknoPass is an automation and management platform developed by Akmer Informatics Automation Industry and Trade Ltd. Co. It functions as a web-based service designed to handle organizational tasks and user interactions, often serving as a central portal for administrative or operational activities.

What does CVE-2026-4104 mean for TeknoPass?

This vulnerability is classified as Improper Neutralization of Special Elements used in an SQL Command, known as CWE-89 or SQL Injection. It occurs when the software improperly handles user-supplied data. In this case, an authorization bypass allows an attacker to manipulate SQL primary key inputs, potentially gaining unauthorized control over the database.

How does an attacker trigger this SQL injection?

An attacker triggers the vulnerability by providing malicious input into a field that the application uses to process primary key queries. The flaw specifically relies on the system accepting user-controlled input without sufficient validation. This does not occur if the input is static, system-generated, or if the interaction path does not involve user-supplied primary key parameters.

Is my TeknoPass instance at risk?

If you host a TeknoPass instance, you should evaluate its accessibility. Halo Surface Signal identifies TeknoPass as a platform typically deployed as a web-based service. Systems configured as internet-facing portals are reachable from the public internet, which increases the likelihood that this vulnerability could be reached by an external actor.

What are the first steps to handle this vulnerability?

Begin by creating a comprehensive inventory of all TeknoPass instances running in your environment. Once you have identified these assets, assess their business criticality and verify whether they are exposed to the public internet. After mapping these details, confirm the internal owner for each instance to coordinate the necessary security updates.
