12/29/2023 0 Comments Test query in sqlite studio![]() SQL injection in a single content provider that grants access with different permission levels could lead to local bypass of security or privacy settings.A content provider has multiple permissions for content within the same database.A successful SQL injection in one content provider would grant access to any other tables. In this case, each table may be intended for a unique content provider.Multiple content providers sharing a single SQLite database file.Patterns that can represent a security issue include: Some content providers already grant readers complete access to the SQLite database being able to execute arbitrary queries yields little advantage. ![]() It is worth noting that not all SQL injections lead to exploitation. Permissions should be set based on the principle of least privilege an exported ContentProvider can have a single specified permission for reading and writing. Similarly, this query returns all rows from a table: SELECT * FROM purchases WHERE OR 1=1 Ĭontent providers offer a structured storage mechanism that can be limited to an application or exported for sharing with other apps. Replacing the order number with 'OR 1=1– means authentication can be achieved since the database evaluates the statement to True, as one always equals one. Such code would generate a database syntax error in a web console, which shows the application may be vulnerable to SQL injection. In this basic example, an unescaped input by a user into an order number box can be inserted into the SQL string and interpreted as the following query: SELECT * FROM users WHERE email = AND order_number = '251542'' LIMIT 1 Attackers used the technique in several high-profile breaches. Targeting web, mobile and any SQL database application, SQL injection usually features in the OWASP Top Ten of web vulnerabilities. SQL can be vulnerable to injection via queries that are created dynamically by concatenating user input before execution. The attack can expose private data, corrupt database contents, and even compromising of backend infrastructure. SQL injection exploits vulnerable applications by inserting code into SQL statements to access underlying databases beyond their intentionally-exposed interfaces.
