Date: 2022-08
Affected: maven/org.dspace:dspace-jspui
Attack vector: info-disclosure
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2022-31189
CWE: CWE-209
CVSS: 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

### Impact When an "Internal System Error" occurs in the JSPUI, then entire exception (including stack trace) is available. Information in this stacktrace may be useful to an attacker in launching a more sophisticated attack. 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/afcc6c3389729b85d5c7b0230cbf9aaf7452f31a * 6.x patch file: https://github.com/DSpace/DSpace/commit/afcc6c3389729b85d5c7b0230cbf9aaf7452f31a.patch (may be applied manually if an immediate upgrade to 6.4 or above is not possible) _DSpace 5.x:_ * The 6.x patch file can also be applied to an older 5.x installation. * Alternatively, you can simply apply the workaround documented below. The detailed error information embedded in `internal.jsp` is not necessary for the JSPUI to function. #### 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 cod
