Critical SQL Injection Flaw Exposes CodeAstro Simple Inventory System 1.0

Overview

CVE-2025-13280 describes a high-severity SQL injection vulnerability found in CodeAstro Simple Inventory System version 1.0. This vulnerability allows a remote attacker to execute arbitrary SQL commands by manipulating the Username parameter during the login process. Publicly available exploits exist, making this a critical issue to address.

Technical Details

The vulnerability resides within the /index.php file, specifically in the Login component. By injecting malicious SQL code into the Username field, an attacker can bypass authentication and potentially gain unauthorized access to sensitive data stored in the database. The vulnerable function does not properly sanitize or validate user input, allowing the injected SQL code to be executed directly against the database.

CVSS Analysis

The vulnerability has a CVSS score of 7.3, classifying it as HIGH severity. This score reflects the following:

• Attack Vector (AV): Network (N) – The attack can be performed remotely.
• Attack Complexity (AC): Low (L) – The attack is relatively easy to execute.
• Privileges Required (PR): None (N) – No privileges are required to exploit the vulnerability.
• User Interaction (UI): None (N) – No user interaction is required to exploit the vulnerability.
• Scope (S): Unchanged (U) – An exploited vulnerability can only affect resources managed by the same security authority.
• Confidentiality Impact (C): High (H) – There is total information disclosure, resulting in all resources within the scope being divulged.
• Integrity Impact (I): High (H) – There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the entire system being impacted.
• Availability Impact (A): High (H) – There is a total loss of availability, resulting in the attacker being able to fully disrupt access to all resources within the scope; not only can the attacker disrupt access to the resources, but in addition the attacker has sabotaged or corrupted these resources to the point that they are no longer recoverable.

Possible Impact

Successful exploitation of this vulnerability can lead to severe consequences:

• Data Breach: An attacker can gain access to sensitive inventory data, user credentials, and other confidential information stored in the database.
• Account Takeover: An attacker can compromise administrator accounts, gaining full control over the system.
• Data Manipulation: An attacker can modify or delete data within the inventory system, leading to inaccurate records and operational disruptions.
• System Downtime: An attacker could potentially disrupt the service availability by injecting malicious code or deleting critical data.

Mitigation and Patch Steps

To mitigate the risk posed by CVE-2025-13280, the following steps are recommended:

1. Apply the Patch: Check the CodeAstro website for official patches or updates. If a patch is available, apply it immediately.
2. Input Validation: Implement robust input validation and sanitization techniques for all user-supplied data, especially the Username parameter in the login form.
3. Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection attacks. This ensures that user input is treated as data rather than executable code.
4. Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to detect and block malicious requests, including SQL injection attempts.
5. Least Privilege Principle: Ensure that the database user used by the application has the minimum necessary privileges to perform its tasks. Avoid using a database user with full administrative rights.
6. Regular Security Audits: Conduct regular security audits and penetration testing to identify and address potential vulnerabilities in the application.
