Daily Tracker System SQL Injection Authentication Bypass CVE-2020-24193

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2020-24193

The vulnerability exists in the login interface of a web-based application. Since login pages are typically exposed to the internet to allow user access to the system, this component is commonly deployed as an internet-facing web service.

Attack Path

How an attacker could exploit the issue

An attacker can exploit this vulnerability by sending a specially crafted request to the login page of the Daily Tracker System. Since no authentication is required, the attacker can bypass the login mechanism by injecting malicious SQL code into the email parameter. This could allow them to gain unauthorized access to the system.

No authentication needed.
Email parameter on login page.
Authentication bypass and data access.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could allow an unauthenticated user to bypass login controls by manipulating the email parameter, potentially granting access to system functionalities.

System login bypassed.
SQL injection via email parameter.
Unauthorized access to system.

Operational Fix

Recommended remediation, mitigation, and detection steps

The critical SQL injection vulnerability in Sourcecodetester Daily Tracker System 1.0's login functionality requires immediate attention from application owners and infrastructure teams. The first practical step is to identify all instances of this system, assess their exposure and business criticality, locate the accountable owner, and then plan remediation based on the risk.

Application owners must address this issue.
Verify system reachability and business criticality first.

Frequently asked questions

What is the Daily Tracker System?

Daily Tracker System is a web-based application designed to help users log and manage daily activities or data entries. It serves as a centralized platform for tracking records, and like many similar tools, it includes a login interface to secure user accounts and manage access to the stored information.

What does CWE-89 mean for CVE-2020-24193?

CWE-89 refers to Improper Neutralization of Special Elements used in an SQL Command, commonly known as SQL injection. In this vulnerability, the system fails to properly filter input, allowing an attacker to insert their own SQL commands into the application's database queries. Because this happens at the login screen, the application mistakenly executes these injected commands as legitimate instructions, which can trick the system into granting access without valid credentials.

How is this SQL injection triggered?

An attacker triggers this vulnerability by inputting malicious SQL code directly into the email field on the application's login page. No special user privileges or prior login are required to perform this action. Notably, interacting with other parts of the application or providing standard, non-malicious email addresses will not trigger this specific authentication bypass.

Is my system at risk?

If you are running Daily Tracker System 1.0, your system is vulnerable. Halo Surface Signal identifies this as an internet-facing risk because the flaw exists within the login page itself. Since login portals are generally intended to be accessible for user authentication, they are frequently exposed to the internet, making it highly likely that any instance of this software is reachable by external actors.

What should I do first to address this?

Your first step is to perform an inventory of your environment to locate all instances of Daily Tracker System 1.0. Once you identify where this software is running, determine who is responsible for each instance and evaluate the business impact of that specific deployment. After you have mapped your assets and confirmed their reachability, you can begin planning the necessary updates or mitigation steps with the application owners.
