How to Fix CVE-2022-31195

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

org.dspace:dspace-api fixed: 5.11
<dependency>
    <groupId>org.dspace</groupId>
    <artifactId>dspace-api</artifactId>
    <version>5.11</version>
</dependency>
org.dspace:dspace-api fixed: 6.4
<dependency>
    <groupId>org.dspace</groupId>
    <artifactId>dspace-api</artifactId>
    <version>6.4</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=org.dspace

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-31195, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.dspace

Analyze the terminal output to locate any version of Dspace api in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.11), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.dspace 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 Dspace api, 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

### Impact ItemImportServiceImpl is vulnerable to a path traversal vulnerability. This means a malicious SAF (simple archive format) package could cause a file/directory to be created anywhere the Tomcat/DSpace user can write to on the server. However, this path traversal vulnerability is only possible by a user with special privileges (either Administrators or someone with command-line access to the server). This vulnerability impacts the XMLUI, JSPUI and command-line. _This vulnerability does NOT impact 7.x._ ### Patches _DSpace 6.x:_ * Fixed in 6.4 via commit: https://github.com/DSpace/DSpace/commit/7af52a0883a9dbc475cf3001f04ed11b24c8a4c0 * 6.x patch file: https://github.com/DSpace/DSpace/commit/7af52a0883a9dbc475cf3001f04ed11b24c8a4c0.patch (may be applied manually if an immediate upgrade to 6.4 or 7.x is not possible) _DSpace 5.x:_ * Fixed in 5.11 via commit: https://github.com/DSpace/DSpace/commit/56e76049185bbd87c994128a9d77735ad7af0199 * 5.x patch file: https://github.com/DSpace/DSpace/commit/56e76049185bbd87c994128a9d77735ad7af0199.patch (may be applied manually if an immediate upgrade to 5.11 or 6.4 or 7.x is not possible) #### Apply the patch to your DSpace If at all possible, we recommend upgrading your DSpace site based on the upgrade instructions. However, if you are unable to do so, you can manually apply the above patches as follows: 1. Download the appropriate patch file to the machine where DSpace is running 2. From the `[dspace-src]` folder, apply the patch, e.g. `git apply [name-of-file].patch` 3. Now, update your DSpace site (based loosely on the Upgrade instructions). This generally involves three steps: 1. Rebuild DSpace, e.g. `mvn -U clean package` (This will recompile all DSpace code) 2. Redeploy DSpace, e.g. `ant update` (This will copy all updated WARs / configs to your installation directory). Depending on your setup you also may need to copy the updated WARs over to your Tomcat webapps folder. 3. Restart Tomcat ### Workarounds As a basic workaround, you may block all access to the following URL paths: * If you are using the XMLUI, block all access to `/admin/batchimport` path (this is the URL of the Admin Batch Import tool). Keep in mind, if your site uses the path "/xmlui", then you'd need to block access to `/xmlui/admin/batchimport`. * If you are using the JSPUI, block all access to `/dspace-admin/batchimport` path (this is the URL of the Admin Batch Import tool). Keep in mind, if your site uses the path "/jspui", then you'd need to block access to `/jspui/dspace-admin/batchimport`. Keep in mind, only an Administrative user or a user with command-line access to the server is able to import/upload SAF packages. Therefore, assuming those users do not blindly upload untrusted SAF packages, then it is unlikely your site could be impacted by this vulnerability. ### For more information If you have any questions or comments about this advisory: * Email us at security@dspace.org
