Example 46 with UpdateRequest

use of org.apache.jena.update.UpdateRequest in project jena by apache.

the class sdbupdate method execOneFile.

private void execOneFile(String filename, Dataset store) {
    UpdateRequest req = UpdateFactory.read(filename, Syntax.syntaxARQ);
    UpdateExecutionFactory.create(req, store).execute();
}

Example 47 with UpdateRequest

use of org.apache.jena.update.UpdateRequest in project jena by apache.

the class TestParameterizedSparqlString method test_param_string_injection_02.

@Test(expected = ARQException.class)
public void test_param_string_injection_02() {
    // This injection is prevented by forbidding the > character in URIs
    String str = "PREFIX : <http://example/>\nINSERT DATA { <s> <p> ?var2 . }";
    ParameterizedSparqlString pss = new ParameterizedSparqlString(str);
    pss.setIri("var2", "hello> } ; DROP ALL ; INSERT DATA { <s> <p> <goodbye");
    UpdateRequest updates = pss.asUpdate();
    Assert.fail("Attempt to do SPARQL injection should result in an exception");
}

Example 48 with UpdateRequest

use of org.apache.jena.update.UpdateRequest in project jena by apache.

the class TestParameterizedSparqlString method test_param_string_positional_injection_09.

@Test
public void test_param_string_positional_injection_09() {
    // This injection attempt using comments results in a valid SPARQL
    // update but a failed injection because the attempt to use comments
    // ends up being a valid string literal within quotes
    String str = "PREFIX : <http://example/>\nINSERT DATA { <s> <p> ? }";
    ParameterizedSparqlString pss = new ParameterizedSparqlString(str);
    pss.setLiteral(0, "\" . } ; DROP ALL ; INSERT DATA { <s> <p> <o> }#");
    UpdateRequest updates = pss.asUpdate();
