AntiSamy is a Java library (also available for .Net) that sanitize the users’ input( e.g. entering the data into website forms) and output to prevent cross-site scripting (XSS) attacks.
The XSS allows attackers to inject malicious code into web pages viewed by other users.
AntiSamy enables web developers to define policy rules that restrict the types of HTML or JavaScript code allowed or send as output, and provides an API to filter and validate input/output against XSS and the application's rules.
Sample AntiSamy file - https://code.google.com/archive/p/owa... the policy file can be customized based on the application's needs.
API - https://mvnrepository.com/artifact/or...
String testHtml="htmlbodyh1 Antisamy Test /h1 a href=\"javascript:callRandom()\"Click Here/a/html";
Policy policy;
try {
policy = Policy.getInstance(TestAntisamy.class.getResourceAsStream("antisamy-slashdot-1.4.3.xml"));
AntiSamy antiSamy = new AntiSamy();
CleanResults cleanResults = antiSamy.scan(testHtml, policy);
System.out.println(cleanResults.getCleanHTML().trim());
} catch (PolicyException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ScanException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
