| CWE ID | Description |
|---|---|
| CWE-89 | The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |
| CWE-74 | The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2026-3755 is a SQL injection vulnerability found in SourceCodester Sales and Inventory System version 1.0. It exists in the POST handler of the file /check_customer_details.php, specifically involving the parameter stock_name1.
The vulnerability arises because the application does not properly sanitize or neutralize special characters in the stock_name1 parameter, allowing an attacker to inject malicious SQL commands.
This flaw can be exploited remotely and may be triggered by an authenticated user sending crafted POST requests, including AJAX calls, to the vulnerable endpoint.
The injection supports multiple SQL injection techniques such as UNION-based, Boolean-based blind, and time-based blind SQL injection, enabling attackers to manipulate the backend database.
