Annotate Java Code

You can add Veracode custom cleanser annotations to your Java code.

To complete this task:

Download the Veracode annotations JAR file from this URL: https://tools.veracode.com/customcleanser/VeracodeAnnotations.jar

Note: Custom cleanser annotations for Java are also available from Maven Central: https://repo1.maven.org/maven2/com/veracode/annotation/VeracodeAnnotations

Reference the custom cleanser annotations package in the project pom.xml file. For example:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    ...
    <dependencies>
        <dependency>        
            <groupId>com.veracode.annotation</groupId>
            <artifactId>VeracodeAnnotations</artifactId>
            <version>[1.0.4,)</version>
        </dependency>
    </dependencies>
    ...
</project>

Build the code using Maven. For example:
```
mvn package
```
When compiling, ensure VeracodeAnnotations.jar is in your classpath.

Import one or more of these cleansers into your Java source file:

Cleanser	Description
`com.veracode.annotation.CRLFCleanser`	Annotates a method that mitigates CWE-93, 113, or 117.
`com.veracode.annotation.FilePathCleanser`	Annotates a method that mitigates CWE-73.
`com.veracode.annotation.RedirectURLCleanser`	Annotates a method that mitigates CWE-601.
`com.veracode.annotation.SQLQueryCleanser`	Annotates a method that mitigates CWE-89.
`com.veracode.annotation.XSSCleanser`	Annotates a method that mitigates CWE-80.

If you want to add custom mitigation text to provide additional information, enter a user comment with this syntax:
```
@FilePathCleanser(userComment = "{your custom text}")
```

Annotate your method with one or more custom cleanser annotations, depending on how the method validates or sanitizes the user-controlled data provided to it, and apply the cleanser method to user-controlled data to ensure it is validated or sanitized before use. For example:

import com.veracode.annotation.FilePathCleanser

public class SecurityUtil
{
   @FilePathCleanser
   public static String myProprietaryFilePathCleanser(String path) {

     // Example file path validatation/sanitization implementation 

     return myCleansedFilePath;
  }
}

// ...

String validatedPath = SecurityUtil.myProprietaryFilePathCleanser(userProvidedFilename);
File myFile = new File(validatedPath);

Results:

Mitigations from Veracode custom cleanser mitigations, including custom mitigation text when provided, appear in the Triage Flaws page, the Application page, and the PDF reports.
