Date: 2022-08
Affected: maven/org.dspace:dspace-jspui, maven/org.dspace:dspace-jspui
Attack vector: path-traversal
Category: vulnerability-disclosure
Severity: High
CVE: CVE-2022-31194
CWE: CWE-22
CVSS: 8.2 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:H)

### Impact The JSPUI resumable upload implementations in SubmissionController and FileUploadRequest are vulnerable to multiple path traversal attacks, allowing an attacker to create files/directories anywhere on the server writable by the Tomcat/DSpace user, by modifying some request parameters during submission. This path traversal can only be executed by a user with special privileges (submitter rights). This vulnerability only impacts the JSPUI. _This vulnerability does NOT impact the XMLUI or 7.x._ ### Patches _DSpace 6.x:_ * Fixed in 6.4 via commit: https://github.com/DSpace/DSpace/commit/7569c6374aefeafb996e202cf8d631020eda5f24 * 6.x patch file: https://github.com/DSpace/DSpace/commit/7569c6374aefeafb996e202cf8d631020eda5f24.patch (may be applied manually if an immediate upgrade to 6.4 or above is not possible) _DSpace 5.x:_ * Fixed in 5.11 via commit: https://github.com/DSpace/DSpace/commit/d1dd7d23329ef055069759df15cfa200c8e3 * 5.x patch file: https://github.com/DSpace/DSpace/commit/d1dd7d23329ef055069759df15cfa200c8e3.patch (may be applied manually if an immediate upgrade to 5.11 or 6.4 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 appl
