HIGH 7.5

DescriptionCVE.org

A Business Logic vulnerability exists in SourceCodester Pharmacy Product Management System 1.0 in the add-sales.php file. The application fails to verify if the requested sales quantity (txtqty) exceeds the available stock level. An attacker can manipulate the request to purchase a quantity that is significantly higher than the actual available stock.

AnalysisAI

SourceCodester Pharmacy Product Management System 1.0 fails to enforce inventory constraints in the add-sales.php module, allowing attackers to create sales transactions for quantities that exceed available stock levels. This business logic flaw enables overselling scenarios where the system processes orders without validating stock availability, potentially leading to negative inventory records and operational disruption. Publicly available exploit code exists demonstrating the vulnerability, though no CVSS scoring or active exploitation via CISA KEV has been confirmed.

Technical ContextAI

The vulnerability exists in a PHP-based e-commerce application (SourceCodester Pharmacy Product Management System) where the add-sales.php file processes sales requests containing a quantity parameter (txtqty). The root cause is insufficient input validation and business logic enforcement-specifically, the application fails to implement server-side verification that compares the requested sales quantity against the current stock level before processing the transaction. This falls under CWE categories related to business logic flaws and insufficient input validation. The affected product is identified as a PHP application managing pharmacy inventory and sales operations, though precise CPE designation data is incomplete in available sources.

RemediationAI

The primary remediation is to implement server-side validation in the add-sales.php file that verifies the requested sales quantity (txtqty) does not exceed the current stock level before processing any transaction. This should include database-level constraints and transactional logic to atomically verify inventory and decrement stock. Contact SourceCodester for an updated version of Pharmacy Product Management System that includes this inventory validation control, or engage qualified PHP developers to patch the application code. As an interim control, implement application-level access restrictions limiting sales entry to trusted administrative users and enable detailed transaction logging to detect and audit overselling attempts. Additionally, conduct a database audit to identify any existing transactions where sales quantities exceed recorded stock levels and reconcile inventory records accordingly.
