**Name of the Vulnerable Software and Affected Versions** Joomla! Core (affected versions not specified) **Description** Lack of escaping in the update list view of the `com installer` component leads to a Cross-Site Scripting (XSS) issue. XSS is a flaw that allows an attacker to inject malicious scripts into web pages viewed by other users. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions SourceCodester Loan Management System version 1.0 Description A business logic flaw exists because the application does not properly validate input. Specifically, the system allows administrators to define 'Loan Plans' with a duration in months, but it does not verify that the duration is a positive integer. An attacker can submit a negative value for the months parameter, and the system will accept this invalid data, creating a loan plan with a negative duration. Recommendations Ensure that the duration value for loan plans is validated to be a positive integer.

Name of the Vulnerable Software and Affected Versions SourceCodester Loan Management System version 1.0 Description A business logic issue exists due to insufficient server-side validation. Administrators can create 'Loan Plans' with penalty rates for overdue payments. The frontend restricts negative values in the 'Monthly Overdue Penalty' field, but this check is absent on the backend. An attacker can bypass the client-side restriction by manipulating the HTTP POST request to submit a negative value for the `penalty rate` parameter. Recommendations Ensure server-side validation is implemented for the `penalty rate` parameter to prevent negative values from being accepted.

**Name of the Vulnerable Software and Affected Versions** SourceCodester Loan Management System version 1.0 **Description** An authenticated attacker can perform a Blind SQL Injection, a technique used to extract information from a database by asking true or false questions. The issue occurs in the 'ajax.php' file within the `save loan` action because the application does not properly sanitize the `borrower id` parameter in POST requests. **Recommendations** Update SourceCodester Loan Management System version 1.0 to a version where the `borrower id` parameter in the `save loan` action of 'ajax.php' is properly sanitized.

**Name of the Vulnerable Software and Affected Versions** SourceCodester Loan Management System version 1.0 **Description** A business logic issue exists due to improper server-side validation. The application allows administrators to create loan plans with specific interest rates. Although the frontend prevents the entry of negative numbers, this constraint is not enforced on the backend. An authenticated attacker can bypass client-side restrictions by manipulating the HTTP POST request to submit a negative value for the `interest percentage` variable, leading to the creation of loan plans with negative interest rates. **Recommendations** Update SourceCodester Loan Management System version 1.0 to a version that implements proper server-side validation for the `interest percentage` variable.

**Name of the Vulnerable Software and Affected Versions** SourceCodester Sales and Inventory System version 1.0 **Description** A Reflected Cross-Site Scripting (XSS) issue exists in the application. The application does not properly sanitize input, which allows for the injection of arbitrary web scripts or HTML. This occurs through a crafted URL targeting the `add customer.php` file via the `msg` parameter. **Recommendations** Apply input sanitization to the `msg` parameter in the `add customer.php` file.
