CVE-2024-25625
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedPimcore's Admin Classic Bundle provides a Backend UI for Pimcore. A potential security vulnerability has been discovered in `pimcore/admin-ui-classic-bundle` prior to version 1.3.4. The vulnerability involves a Host Header Injection in the `invitationLinkAction` function of the UserController, specifically in the way `$loginUrl` trusts user input. The host header from incoming HTTP requests is used unsafely when generating URLs. An attacker can manipulate the HTTP host header in requests to the /admin/user/invitationlink endpoint, resulting in the generation of URLs with the attacker's domain. In fact, if a host header is injected in the POST request, the $loginURL parameter is constructed with this unvalidated host header. It is then used to send an invitation email to the provided user. This vulnerability can be used to perform phishing attacks by making the URLs in the invitation links emails point to an attacker-controlled domain. Version 1.3.4 contains a patch for the vulnerability. The maintainers recommend validating the host header and ensuring it matches the application's domain. It would also be beneficial to use a default trusted host or hostname if the incoming host header is not recognized or is absent.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisUntrusted input crosses into a downstream interpreter — SQL, a shell, an HTML page, an LDAP query — without being kept separate from the commands around it, so the attacker's data is read as instructions. This is the parent class behind SQL injection, cross-site scripting, and command injection alike. The durable fix is the same everywhere: keep data and code apart at every boundary, using parameterisation or context-aware encoding rather than building interpreted strings by concatenation.

dbcve · scoped1.3.4
pimcore/admin-ui-classic-bundle version 1.3.4
- Update the composer.json file to require pimcore/admin-ui-classic-bundle version 1.3.4 or higher
- Run 'composer update pimcore/admin-ui-classic-bundle' to install the patched version
- Clear the application cache (e.g., 'bin/console cache:clear' or 'bin/console cache:clear --env=prod')
- Verify the upgrade by checking the installed version with 'composer show pimcore/admin-ui-classic-bundle'
- Test the /admin/user/invitationlink endpoint to confirm invitation emails now generate URLs with the correct application domain
