Description

A security flaw has been discovered in amirsanni Mini-Inventory-and-Sales-Management-System up to 81bf0b55f5933f3b0dbb1583204a612e06605b95. The impacted element is the function order_by of the file DB_query_builder.php of the component Database Query Builder. Performing a manipulation of the argument orderBy results in sql injection. Remote exploitation of the attack is possible. The exploit has been released to the public and may be used for attacks. This product follows a rolling release approach for continuous delivery, so version details for affected or updated releases are not provided. The project maintainer confirms: "I stopped maintaining that project for a while now, so I'm not sure it's worth fixing." This vulnerability only affects products that are no longer supported by the maintainer.

  "executiveSummary": "A critical SQL injection vulnerability exists in the 'order_by' function within the 'DB_query_builder.php' component of the amirsanni Mini-Inventory-and-Sales-Management-System (up to commit 81bf0b55f5933f3b0dbb1583204a612e06605b95).\nThe vulnerability arises from improper neutralization of input provided to the 'orderBy' argument, allowing unauthorized actors to manipulate database queries.\nSuccessful exploitation permits remote attackers to execute arbitrary SQL commands against the backend database, potentially leading to unauthorized data exfiltration, modification, or total compromise of the database layer.\nThe project maintainer has confirmed that the software is no longer supported or maintained, meaning no official patches will be released.\nGiven that public exploit code is available, the risk to instances of this software is high. Systems utilizing this component should be considered insecure and require immediate isolation or replacement.",
  "technicalDetails": "The vulnerability is situated within the 'order_by' method of the 'DB_query_builder.php' file, which serves as a core database abstraction layer for the Mini-Inventory-and-Sales-Management-System.\nThe root cause is an insufficient sanitization mechanism for user-supplied input passed through the 'orderBy' argument before it is concatenated into a raw SQL query string. Because the application logic fails to employ parameterized queries or strict input validation (such as whitelisting allowed column names), the input is treated as trusted executable code by the database engine.\nThe exploitation flow initiates when a remote attacker sends a specially crafted HTTP request targeting an endpoint that utilizes the 'order_by' function. By injecting malicious SQL syntax into the 'orderBy' parameter, the attacker can break out of the intended query structure.\nThis allows for various malicious activities, such as utilizing 'UNION SELECT' statements to retrieve data from unrelated tables, performing blind SQL injection for systematic data exfiltration, or modifying existing records. In some configurations, if the database user permissions are overly permissive, an attacker might escalate to administrative functions or manipulate the underlying file system if the database server allows it.\nSince the project follows a continuous delivery approach without formal version tagging, all implementations up to commit 81bf0b55f5933f3b0dbb1583204a612e06605b95 are affected. No authentication is strictly required to reach the injection point, depending on the application's implementation of the query builder, increasing the potential attack surface. The availability of public exploits significantly lowers the barrier to entry for attackers, requiring minimal technical sophistication to weaponize the flaw against exposed instances."
