Lifecycle Timeline
3Description
OpenSourcePOS 3.4.1 has a second order SQL Injection vulnerability in the handling of the currency_symbol configuration field. Although the input is initially stored without immediate execution, it is later concatenated into a dynamically constructed SQL query without proper sanitization or parameter binding. This allows an attacker with access to modify the currency_symbol value to inject arbitrary SQL expressions, which are executed when the affected query is subsequently processed.
Analysis
OpenSourcePOS 3.4.1 allows authenticated attackers to execute arbitrary SQL commands through unsanitized concatenation of the currency_symbol configuration parameter into dynamic database queries. An attacker with administrative privileges can exploit this second-order SQL injection to access or manipulate sensitive data. …
