CVE-2026-71207 in Stock-Inventory-Management-System
Summary
by MITRE • 08/05/2026
The Stock-Inventory-Management-System application's login.php assigns raw $_POST username/password values to $_SESSION and builds its authentication query by directly concatenating those session values into a SQL statement with no parameterization or escaping. An unauthenticated remote attacker can submit a payload such as ' OR '1'='1 in the login form to bypass authentication entirely. The same script additionally contains hardcoded administrative credentials (admin/neola) in a post-login conditional check, providing a second, independent full-authentication-bypass path.

The vulnerability identified in the Stock-Inventory-Management-System application represents a critical authentication bypass flaw that stems from improper input handling and weak security practices within the login.php script. This weakness creates multiple attack vectors that can be exploited by unauthenticated remote attackers to gain unauthorized access to the system. The core technical issue manifests through the direct use of raw $_POST values in session variables without any sanitization or validation, followed by their inclusion in SQL queries through string concatenation rather than parameterized statements.
The primary vulnerability aligns with CWE-89, which specifically addresses SQL injection flaws occurring when user-supplied data is directly incorporated into SQL commands without proper escaping or parameterization. The application's login mechanism fails to implement any form of input validation or sanitization for the username and password fields, allowing attackers to inject malicious payloads that manipulate the authentication logic. When an attacker submits a payload such as ' OR '1'='1 into the login form, the system processes this input without proper escaping, causing the SQL query to return true for all users and effectively bypassing authentication entirely.
The vulnerability extends beyond basic SQL injection through the presence of hardcoded administrative credentials within the application code. This design flaw creates a second independent path for authentication bypass, as demonstrated by the hardcoded values admin/neola present in the post-login conditional checks. This dual vulnerability architecture significantly increases the attack surface and provides multiple opportunities for exploitation regardless of whether the primary SQL injection vector is successfully executed.
The operational impact of this vulnerability is severe and far-reaching, as it allows attackers to gain full administrative access to the inventory management system without requiring legitimate credentials or prior authorization. Once authenticated, an attacker can manipulate all aspects of the inventory system including adding, modifying, or deleting stock records, viewing sensitive data, and potentially using the compromised system as a pivot point for further attacks within the network. The remote nature of this vulnerability means that attackers can exploit it from anywhere on the internet without requiring physical access to the system.
Security professionals should note that this vulnerability demonstrates poor application security practices that violate fundamental principles of secure coding and defense in depth strategies. The combination of SQL injection and hardcoded credentials represents a classic example of insufficient input validation combined with weak credential management, creating an attack surface that requires immediate remediation. The presence of multiple bypass paths makes this vulnerability particularly dangerous and difficult to detect through simple security scanning tools.
Mitigation strategies should include implementing proper parameterized queries for all database interactions, removing hardcoded credentials from the application source code, and enforcing strong input validation on all user-supplied data. The system must also implement proper session management practices including secure session handling, input sanitization, and regular credential rotation. Additionally, organizations should conduct comprehensive security testing including penetration testing and code reviews to identify similar vulnerabilities throughout their applications. This vulnerability also aligns with ATT&CK technique T1078 which covers legitimate credentials usage, as the authentication bypass allows attackers to operate under valid user accounts within the system.
The remediation process must address both the immediate SQL injection vulnerability through proper parameterization of database queries and the long-term security issue of hardcoded credentials by implementing secure credential management practices. This includes migrating from static credential storage to secure configuration management systems and implementing proper access controls that follow the principle of least privilege. Organizations should also implement monitoring and logging mechanisms to detect unauthorized authentication attempts and potential exploitation of similar vulnerabilities in other system components.
The vulnerability serves as a stark reminder of how simple coding mistakes can lead to catastrophic security consequences, particularly when dealing with authentication mechanisms that form the cornerstone of application security. The lack of proper input validation and secure coding practices in this example demonstrates why organizations must invest in comprehensive security training for developers and implement automated security testing into their development lifecycle processes. This type of vulnerability is often detectable through static code analysis tools and should be prevented through proper security architecture reviews and adherence to established secure coding standards and best practices.
