How to Fix CVE-2022-4493

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

io.scif:scifio fixed: 0.43.3 
<dependency>
    <groupId>io.scif</groupId>
    <artifactId>scifio</artifactId>
    <version>0.43.3</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=io.scif

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-4493, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.scif

Analyze the terminal output to locate any version of Scifio in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.43.3), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.scif 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Scifio, 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

A vulnerability classified as critical was found in scifio. Affected by this vulnerability is the function downloadAndUnpackResource of the file src/test/java/io/scif/util/DefaultSampleFilesService.java of the component ZIP File Handler. The manipulation leads to path traversal. The attack can be launched remotely. The patch is at commit fcb0dbca0ec72b22fe0c9ddc8abc9cb188a0ff31. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-215803.
