How to Fix CVE-2019-17352

To remediate this vulnerability, upgrade all affected Jfinal dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.jfinal:jfinal fixed: 4.5 
<dependency>
    <groupId>com.jfinal</groupId>
    <artifactId>jfinal</artifactId>
    <version>4.5</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=com.jfinal

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2019-17352, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.jfinal

Analyze the terminal output to locate any version of Jfinal in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.5), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.jfinal command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-434: Unrestricted Upload of File with Dangerous Type, where the product allows the upload or transfer of dangerous file types that are automatically processed within its environment. In Jfinal, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In JFinal cos before 2019-08-13, as used in JFinal 4.4, there is a vulnerability that can bypass the isSafeFile() function: one can upload any type of file. For example, a .jsp file may be stored and almost immediately deleted, but this deletion step does not occur for certain exceptions.
