Description

A weakness has been identified in itsourcecode Sales and Inventory System 1.0. This affects an unknown function of the file /pages/cust_pos_trans.php. Executing a manipulation of the argument firstname can lead to sql injection. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks.

  "executiveSummary": "A critical SQL injection vulnerability exists in the Sales and Inventory System version 1.0, specifically within the /pages/cust_pos_trans.php script.\nThis vulnerability allows unauthenticated or remote attackers to manipulate the 'firstname' argument, enabling the injection of malicious SQL commands directly into the backend database query.\nThe flaw permits unauthorized access to sensitive data, potential modification or deletion of records, and significant compromise of the system's data integrity.\nGiven that exploit code is publicly available, the risk of exploitation by malicious actors is high.\nThe attack vector is remotely exploitable, requiring no prior authentication or administrative privileges, making it a high-priority security concern for deployments of this system.",
  "technicalDetails": "The vulnerability originates from improper neutralization of user-supplied input within the /pages/cust_pos_trans.php file. The 'firstname' parameter is passed directly into a database query without adequate sanitization, validation, or the use of prepared statements.\nThe root cause is a failure to implement parameterized queries or input filtering, which allows an attacker to break out of the intended SQL syntax. By injecting crafted SQL payloads into the 'firstname' input field, an attacker can manipulate the query logic, perform unauthorized data exfiltration via UNION-based attacks, or execute stacked queries depending on the database configuration.\nThe attack flow proceeds as follows: An attacker sends a crafted HTTP request to the /pages/cust_pos_trans.php endpoint. The malicious payload, embedded within the 'firstname' argument, is processed by the application's backend logic. Because the application concatenates this input directly into the SQL statement, the database management system (DBMS) interprets the malicious characters (such as single quotes, semicolons, or comment indicators) as operational code rather than literal data. This results in the execution of unauthorized commands.\nThis vulnerability is classified as an SQL injection (SQLi) flaw. The lack of input validation and reliance on insecure dynamic query construction exposes the underlying database to full control. Successful exploitation leads to a direct impact on the confidentiality, integrity, and availability of the information stored within the system's database. An attacker could retrieve administrator credentials, dump entire customer tables, or modify transaction records to facilitate fraudulent activities.\nThe vulnerability is remotely exploitable over a network. Since the exploit is publicly available, it does not require sophisticated reverse engineering, allowing low-skill actors to execute the attack. Post-exploitation impact may extend beyond the database, as attackers could potentially use database functions to interact with the underlying host file system or network, depending on the database user's permissions and the configuration of the web application environment."
